Why can't I log into the iTunes store? If you can't connect to the iTunes Store, iBooks Store, or App Store. For devices on Mac OS X

Articles and Lifehacks

Similar complaints are increasingly coming from owners of iOS devices. Owners of tablet computers, players and smartphones often note that they Can't connect to iTunes Store regardless of whether they can and what version of the operating system they are using.

There can be quite a few reasons for such a problem - just like there are ways to troubleshoot problems. Sometimes simply rebooting the mobile device or updating the platform version helps. In other cases, the DNS settings of the Wi-Fi network are changed. Let's look at the two most common ways to solve this problem.

What should we do if we can't connect to the iTunes Store?

Owners of all Apple mobile devices, regardless of operating system version, can try the first method. We go to the main settings and look for an item called “Reset”, and in it there is an option responsible for resetting all settings. Let us add that if the device password was initially set, the system will definitely require it.

The above actions will not affect the contents of the device in any way. Only the settings will be reset, but the content will remain in place.
Another way is to change the date and time zone. It is quite difficult to explain exactly how this works, but in practice it turns out to be very effective. So, let's go to the main settings and look for the menu responsible for the time and date. Uncheck the “Automatic” box. Set an arbitrary locality and change the year to 2038.

Next, we load the App Store, select the “Updates” section and see that we cannot connect to the iTunes store. We return again to the time and date settings, after which we change them to the original values. Now we wait for a while and reboot the device. Sometimes after this it can already connect to the iTunes Store.

Can't connect to the iTunes Store: Solution from Apple Support

What does support offer if my iOS device has no access to the store at all? First, let's make sure that the latest versions of the software are installed on the device, and where they should be; the same applies to the PC from which they are trying to log in. The operating system should not be outdated, and the computer must meet the minimum system requirements that are necessary for iTunes to work correctly.

If we use a Mac, we select "Software Update" from the Apple menu and see if any updates are currently available. As for Windows, visit the Microsoft Update Center web page.

Now regarding the mobile device. We check the date and time, the availability of the latest version of the operating system and software updates (through the main settings). You can also try connecting your iOS device to iTunes and selecting the “Update” command (you can find it on the “Browse” page).
We need to make sure that we are within range of a Wi-Fi network. If there is no Internet connection, we try to see if other equipment can connect to Wi-Fi. We check the activation of cellular communications through the basic settings of the mobile device.

What should I do if I still can't connect to the iTunes Store? Sometimes problems can occur on the computer itself. For example, Mac users are aware of cases of software or provider conflicts, as a result of which access is blocked. In this case, you need to update your Safafi browser, as well as iTunes, to the latest version. Sometimes resetting the keychain helps, or contacting your Internet provider.

Windows users are also encouraged to update iTunes. Setting your firewall to allow access may help. Problems are also possible due to proxy servers (it is better not to use them). If the problem still cannot be solved, contact the provider.

Check your settings and network connections to try to resolve the issue on your iPhone, iPad, iPod touch, Apple TV, or Mac or PC.

If the iTunes Store, App Store, or iBooks Store loads as expected, but you can't sign in, you can.

Availability and store features may vary by country or region.

Checking the connection

Make sure your device is connected to the Internet. Try opening a website in your browser. If the site does not open, try the same on another device connected to the same network. If other devices can't access the Internet, turn your Wi-Fi router off and on again to reset it. If you still can't connect to your Wi-Fi network, contact your Internet service provider for further assistance.

Checking the System Status

On a Mac or PC

Follow the instructions for your computer.

On a Mac

By default, the built-in software firewall in macOS automatically allows Apple-signed programs to accept incoming connections. If the firewall settings for programs have been changed, this may be required. If the problem persists, reset the accepted certificate cache:

Other messages when connected

The steps in this article may also help you troubleshoot the following error messages.

Any citizen who owns an expensive flagship from Apple, let it be an iPhone or any gadget, may encounter the following problem - “It will be impossible to enter the official application store (App Store). As they say as a joke: everyone has a 50 to 50 percent chance of stumbling upon such a disaster. This means that the problem can happen to any user, regardless of the device used, and regardless of any social or other characteristics.

If such an error occurs on an Apple mobile device, there is no need to panic, much less do a hard reset (deleting all settings and personal data on the mobile phone), because it is enough to solve this problem differently. The error may appear differently on each Apple device. However, in ninety percent of cases, users report messages related to this problem such as “App Store connection failed,” “unable to connect to app store,” and so on.

Why can't I connect to the iTunes store?

Usually this problem appears after a person wants to install some kind of program update on his smartphone or, in general, download a completely different application (game), and he gets a kind of error due to problems that could have been noticed many times before by himself users.

Here is a list of sample problems that may prevent you from connecting to the iTunes store:

The date and time were set incorrectly on the smartphone. It may be that the connection to the correct time zone is missing.
The serial number of the Apple device could be hidden, and because of this, the error actually pops up - “cannot connect to the iTunes store.” However, dealing with this problem is quite simple: first go to the “Settings” section, select “About device” and make sure that the values we need are there.
The third problem, due to which an information error can pop up, is usually called “Lack of a normal Internet connection.” Apple developers have repeatedly repeated: “For the normal functioning of the App Store, high-quality Internet is necessary.” Therefore, if there are problems with the Wi-Fi network at home, there is a chance that this error will pop up repeatedly.
Expired (invalid) root certificates stored on the device can also become a problem, due to which an informative message will appear - iTunes was unable to connect to the iTunes store. This case can be treated simply. It is necessary to delete two files from the certificates folder, namely “ocspcache.db”, “crlcache.db”. Next, you need to reboot your device and try logging into the App Store again.

Initial steps to take when the “App Store connection failed” error occurs.

Before following the suggested recommendations or seeking help from specialists, you must carefully examine the router (modem) you have at home. If your Internet connection is working properly, you can try logging into your Apple ID in a new way on your mobile device, then restart your phone later and check the functionality of the App Store servers. There are times when the simple procedure of “Log out of your account” and re-enter the necessary data helped solve this problem and you didn’t have to spend a lot of time fixing the existing problem.

Conclusion

Perhaps, this has covered all the ways to solve the problem of connection failure to the App Store. If a message appears, then don’t start worrying, just pull yourself together, try logging into your Apple ID account in a new way, reboot your mobile phone, try updating the software (version of the iOS operating system) and see if the existing problem is solved. At times, excessive actions taken by a person can cause more harm than good. There is no need to immediately do a Hard Reset, even if you have a saved copy of your personal data and applications, because restoring this copy may also cause some problems. It's better to start small and watch the results.

Wi-Fi connections never cease to surprise us with new types of malfunctions. In today's brief excursion we will consider the problem "". Most likely, you encountered it when you tried to connect a friend’s laptop to the network or after the connection to the device was interrupted. There is nothing wrong with this, you just need to adjust the network parameters and it will start.

Why can't I connect to a Wi-Fi network?

Windows was unable to connect to the network for various reasons, usually the problem is a failure of the Wi-Fi router itself, probably the automatic settings have gone wrong, or there is a problem in Windows. Most often, the point is to change the network password or change the encryption type, perhaps even without your participation. In any case, there is a fairly effective remedy for this problem; you just need to reconnect to the network, like a new device.

Before “sorting out” the system, you should try to restart the device, which helps in most cases. Sometimes you have to repeat the procedure two or three times. Then run:

Click on the icon in the Wi-Fi connection tray (inactive, of course);
Expand the full list of settings by clicking on “Network settings”;

Click the “Manage Wi-Fi network settings” link again;

Select the network with the problematic connection and click on “Forget”;

Reconnect to the network.

Most often, the problem goes away at this stage, but only if the cause is superficial and is not related to a failure in the router parameters, otherwise diagnostics should be continued.

In some cases, a scan is launched that identifies network requirements, the password window does not even appear, and the scan takes forever. You will have to perform a full reboot of the device.

If it still says “Could not connect to the network,” we continue to eliminate the parameters that were changed and block the connection using drivers. This is what follows:

Click on Start and right-click on “Computer”, then “Properties”;
Select “Device Manager”;
Expand the “Network adapters” list;
RMB on the required item and “Delete”;

This is how it would seem that a laptop (netbook, etc.) works with a Wi-Fi network and no questions asked. And one day you turn it on and an error appears: “Windows was unable to connect to Wi-Fi...”. What to do?

This is exactly what happened with my home laptop. In this article I want to tell you how you can eliminate this error (besides, as practice shows, this error is quite common).

The most common reasons:

1. Lack of drivers.

2. The router settings are lost (or changed).

3. Antivirus programs and firewalls.

4. Conflict between programs and drivers.

And now about how to eliminate them.

Resolving the error "Windows could not connect to the Wi-Fi network"

1) Setting up Windows OS (using Windows 7 as an example, similar in Windows 8).

If you still receive an error stating that it is not possible to connect to the network (as in the picture below), click on the " troubleshooting"(I know that many are very skeptical about her (I was the same way until she helped restore the network a couple of times)).

If the diagnostics did not help, go to " Network and Sharing Center" (to enter this section, just right-click on the network icon next to the clock).

Now we simply delete our wireless network, which Windows cannot connect to (by the way, you will have your own network name, in my case it is “Autoto”).

We try again to connect to the Wi-Fi network that we deleted in the previous step.

In my case, Windows was able to connect to the network, and without any questions. The reason turned out to be trivial: one “comrade” changed the password in the router settings, and in Windows, in the network connection settings, the old password was saved...

2) Setting up a Wi-Fi network in the router

After checking your wireless connection settings in Windows, the second thing you need to do is check your router settings. In 50% of cases, they are to blame: either they went wrong (which could happen, for example, during a power outage), or someone changed them...

Because If you were unable to access the Wi-Fi network from your laptop, then you need to set up the Wi-Fi connection from a computer that is connected to the router using a cable (twisted pair).

In order not to repeat myself, here is a good article about. If you can’t log in, I recommend checking out this:

In the router settings We are interested in the “Wireless” section (if in Russian, then setting up Wi-Fi parameters).

For example, in TP-link routers this section looks something like this:

Setting up a TP-link router.

By the way, in some cases you may need to reset your router(s). There is a special button on its body for this. Press it and hold it for 10-15 seconds.

Task: change the password and try to set up a wireless connection in Windows (see point 1 of this article).

3) Update drivers

The lack of drivers (as well as the installation of drivers that are not suitable for the equipment) can cause much more serious errors and failures. Therefore, after checking the router settings and network connection in Windows, you need to check the drivers for the network adapter.

How to do it?

4) Setting up startup and disabling antiviruses

Antiviruses and firewalls (with certain settings) can block all network connections, supposedly protecting you from dangerous threats. Therefore, the easiest option is to simply disable them or delete them during setup.

Regarding startup: during setup, it is also advisable to remove all programs that automatically load with Windows. To do this, press the key combination "Win + R" (valid in Windows 7/8).

Very often, when connecting to a wireless network, users encounter various errors. Probably the most common is that Windows was unable to connect to the WiFi network. What is this error and how can I fix it? This is what we will talk about.

But before moving on to connection problems and their solutions, first a few words about how a wireless network works. The fact is that WiFi routers are usually used to create private groups. It is to them that the computer is subsequently connected. This means that first of all, if you encounter any connection problems, you need to check your access point (router).

There are more than enough reasons for such an error to appear. It is simply impossible to consider each of them. Therefore, let's look at the most common problems with connecting to a WiFi network and their solutions. So, if the computer sees the network, but cannot connect to it, then you should check the following parameters:

Checking for correct insertion.
Router settings.
Checking drivers.
Wireless connection settings in Windows.
Firewall and antivirus program settings.

There may also be conflicts between programs and drivers, and even malfunctions of the wireless adapter. Let's go in order.

Checking the network key

Very often the reason for a connection error is a password mismatch. This means that you simply made a mistake when entering the key. Therefore, first of all, you should check that the code is written correctly. Try connecting to the network again, but carefully check your keyboard layout and whether Capslock is enabled.

Setting up the router

If you are still sure that the entered key is correct, then you should check the router settings. To do this, connect to it using a cable. Next, open your favorite browser and enter the router’s IP in the address bar. It is indicated on the bottom panel of the device, as well as in the instructions (if available).

How to easily find out the IP address of a WiFi router: Video

Now we will need to enter a password and login. Initially, this is admin, admin, respectively. If you have already changed this data, then enter your values. After that, go to the settings menu. Everything is simple here. We are interested in setting up a wireless network (Wi-Fi). Find the Security Settings. You need to find the network key in the security settings. If necessary, you can change it.

Next, you should check the MAC address filter. It is possible that you, or someone else who has access to the router (it is possible), entered your computer into the filter by MAC address. Because of this, even with the correct password, you will not be able to connect to the WiFi network.

To check this, you need to go to the “MAC-Filtering” item in the wireless network settings and check if there are any devices there. You don't need to find out the MAC address of your computer; you just need to remove all devices on it from the list.

How to set up a MAC filter in a router: Video

It is also recommended to reboot the router, as they may malfunction. This applies to absolutely all models, from budget to the most expensive. If you have done all the above steps, and Windows still cannot connect to the WiFi network, then go to the operating system settings.

Checking drivers

Articles on the topic
First of all, it is necessary. The fact is that any version of Windows needs hardware software, since a special program is needed for the operation of a particular module. The operation of the equipment (in our case, the wireless module) also depends on its correct operation.

So, you can check this in the task manager. You can open this service in any version of Windows through the properties of my computer. Find “My Computer” on the desktop or in the start menu, right-click on it and select “Properties”. In the window that appears, in the left menu we find “Device Manager”. Now we need to find the branch called “Network Adapters” and open it.

If there is no such branch, then this indicates that there are no drivers for network cards. In this case, they need to be installed. But if you can turn on the WiFi module, and the computer sees available networks, but cannot connect to them, then the drivers must be installed. The only question is whether they work correctly. So, open the network adapters branch. It must contain at least two devices:

Network adapter.
Wireless Network Adapter.

In addition, there may be Bluetooth devices and other network modules. If the wireless adapter is highlighted with an exclamation mark, this means that the drivers are not working correctly. There may also be other problems. You can find out the error by right-clicking on the module and selecting “Properties”.

In the window that appears, in the “General” tab (usually the first one that opens), you will find the “Device Status” item. The error and its number will be indicated here (if the device is not working correctly). Knowing the error, you can find a way to fix it. As a rule, reinstalling the driver solves all problems.

Reinstalling the driver is extremely simple. It is available on the disk that came with the laptop. But even if there is no such disk, you can download them from the official website of the laptop manufacturer. After downloading and installing, test their software as above and try connecting to your network.

How to reinstall the WiFi driver: Video

Setting up a wireless connection in the Windows Management Console

First of all, we need to open the Network and Sharing Center. It is this tool that allows you to manage all network connections, including wireless ones. There are several ways to do this, but we will look at the simplest one.

Find the network icon in the tray (lower right corner), right-click on it and select “Network and Sharing Center”. In the window that appears, we are primarily interested in the “Change adapter settings” item. Now we are in a service that allows you to manage connections. Find the “Wireless Network” shortcut. Right-click on it and select “Properties”.

In the window that appears, in the “Network” tab, you need to find Internet Protocol version 4 TCPIPv4. Select it and click “Properties”. In the menu that appears, you need to check the “Obtain an IP address automatically” checkbox. A little lower, it is also worth setting a marker on automatic data acquisition. Click “Ok”, close the window and try to connect to the network.

If Windows still cannot connect to the network, then return to the control center and select “Manage wireless networks”. Find the desired network in the list and click “Adapter Properties”. Next, we check the TCPIPv4 protocol, as described above. We try to connect again.

If the problem is not resolved, go to the “Manage Wireless Networks” menu, find and delete the desired network. Don't worry, Windows will still find it. This is necessary to reset all connection parameters.

System diagnostics

If you have completed all of the above steps, and the system still gives an error and Windows is unable to connect to the WiFi network, then you need to run diagnostics. There are several ways to enable it. It is worth noting that if any errors occur, as a rule, the system itself offers diagnostics. But if this still does not happen, then the fastest way to launch it is to right-click on the network icon in the tray and select “Diagnostics problems”.

After this, the system will automatically begin searching for and eliminating errors. All you have to do is follow the prompts on the screen. It should be noted that such diagnostics can be performed several times in a row, since Windows does not always find and fix the error the first time.

We looked at the most common errors that you can fix yourself. However, more serious mistakes also occur that require an individual approach. All records of problems and failures are contained in the Windows log. If necessary, you can look at it and find out the error code associated with the wireless connection. This will help you find a solution faster.

How to view the Windows event log

On all operating systems, this log is located in one place. In order to open it, you need to find the “My Computer” shortcut. It can be on the desktop, in the start menu, or in the file manager. Right-click on it and select “Manage”.

In the window that appears, in the left menu we find “Event Viewer”. Open it and find the “Windows Logs” folder. Let's open it. Now we find the “System” item. This is the required journal. Let's open it. When opening, you will need to wait a little, since the system has a huge number of records, scanning which takes some time.

In this log, warnings are marked with yellow triangles with exclamation marks inside, and errors are marked with red circles. Now all you have to do is find the error related to Internet connection or local networks in the list and open it

The error “iTunes could not connect to this iPhone” appears on Apple devices when connected to a computer. It can be caused by several factors. Problems can be with a mobile device, namely outdated software, failures, etc., with a computer - also failures, blocking by anti-virus software, or by the iTunes service. So we will figure out what exactly influenced the appearance of error 0xe8000015 with an unsuccessful connection to the phone.

Error 0xe8000015

Fixing an error in iTunes. Delete the Lockdown folder

To fix the problem “iTunes could not connect to this iPhone” (0xe8000015), first of all we will check the files that are on your computer for device interaction. To do this, we will delete one folder in the system related to the phone.

Close all windows and applications, including the iTunes application.
Disconnect the cable from the computer; this must be done immediately when error 0xe8000015 appears.
Open the task manager on your computer by pressing CTRL+SHIFT+ESCAPE.
Select the “Processes” section at the top of the program.
Find here the running processes that are currently redundant AppleMbileDveice.exe, iTunesHelp.exe, APSDaemon.exe. and others that apply to your mobile device and iTunes store. The names of the processes may differ slightly, depending on the versions of the programs.

Now let's move on to deleting the Lockdown folder. To do this in Windows XP, Vista, 7:

Open the Run window (to do this, press the WIN+R key combination).
On a blank line, type the following command %AllUsersProfile% and run it by pressing Enter.
Next, the Application Data folder will open (it can only be read).
Then find and go to the Apple folder.
Select Lockdown in the list and right-click and select the “Delete” line.

Steps to fix the error for Windows 8 and 10

Then connect the device (iPhone) to the computer again and launch the iTunes store application. If the services are corrected, you will receive a message from the system about allowing access to information; agree by clicking “Continue”. To do this, you may need to confirm your actions on your mobile device.

Personal Computer

If you are trying to open the store from your computer, that is, through the iTunes media player, then you first need to make sure of the following:

Is there internet access? To do this, try going to any website, for example, Google. If it opens, then proceed to the next step.

We make sure that the PC clearly meets the minimum system requirements of iTunes (it can only fail to meet if your computer is from the 90s of the last century).

The manufacturer also recommends updating the operating system to the latest version, but in reality this is unlikely to help, since iTunes supports a lot of OSes, including quite old ones.

Another solution is to wait a while. It is possible that there was a small glitch in the store and after some time the problems will be corrected.

We follow further - be sure to update the version of iTunes to the latest. You can do this on the official Apple website or through the program itself (with old software you may actually not be able to get into the online store).

Next, we try to disable the firewall and antivirus, which may be causing the problem. If desired, add the store to the exclusion list.

If it doesn’t work, go to “Internet Options”. Already here we are looking to see if there are proxy servers by default? If there are any, delete them, and then try to go to the iTunes Store.

It is theoretically possible that there is a problem with the ports on the side of your Internet provider - you can contact them with this question, but in 99% of cases the problem is on the user's side.

Finally, you can check the hosts file, which viruses and Trojans love to attack. By default, it is located in the C:\WINDOWS\SYSTEM32\DRIVERS\ETC folder. We open it with notepad and see inscriptions with IP addresses. Find line 127.0.0.1 localhost and delete all addresses that are below this entry. After deleting them, close the file, confirm saving, and try to go to the store. Happened? Great, now be sure to scan your computer with an antivirus - it most likely contains malware.

iPhone, iPad or iPod touch

If you are trying to access the iTunes Store using one of the devices mentioned above, the first thing you need to do is make sure that you are using the latest firmware at the moment. If this is not the case, then update the software (although if you have an iPhone, then this must be done carefully so as not to get ).

You also need to make sure that you are currently within range of a WI-FI station or routing station. If you access the network through the Internet of your mobile provider, make sure that 3G support is enabled. By the way, when working with 2G networks, downloading large elements, such as applications, may not occur. Meanwhile, we have already written about this in more detail on our website.

You can also try resetting your WI-FI router, this helps quite often. Alternatively, you can try rebooting your device.

Here is a possible solution to the problem that we discovered on the Internet. To do this, select the network you need, then use the arrow on it to go to settings. In the “DNS” line, delete all entries, and instead write the numbers (without quotes) “8.8.8.8”. Click “Update rental”, turn Wi-Fi off and on, try to go to the store. It should help, however, the settings, as far as we know, are not saved.

Dear readers! If you have another way to solve the problem, please write about it in the comments.

The iTunes Store is Apple's online shopping center. In this virtual object there are different folders: music, movies, game applications, books and much more. This “cloud” helps to establish more convenient access to the files you need. Thanks to this storage, it has become easier to find and download any content. But sometimes the phone says “Cannot connect to the iTunes Store.” Is there any way to fix this?

Why is this happening?

The reason for this problem may be the following:

the date and time are incorrectly determined, there is no reference to the correct time zone;
the error may occur on the smartphone if its serial code is hidden;
Sometimes you can’t connect to the iTunes Store due to a poor Internet connection; it’s best to use Wi-Fi, because mobile traffic may not load “heavy” programs (games, for example).

Expired certificates stored on a smartphone can also become a problem.

What do we have to do?

What can you do if you are unable to connect to the iTunes Store iPhone? First of all, you need to reset all phone options. To do this, follow the steps below.

Once you complete the previous step, change the date and time zone. To do this, you should also go to “Settings”, then select “General”, then go to the “Date and Time” sub-item. Uncheck “Automatic”, then put, for example, 2038, put a city of your choice.

Then log into the AppStore and open the Updates section. You should see a message saying that your device can't connect to the iTunes Store. This is to be expected. At this point, look again at the date and time options, set the original current date.

The problem may not go away immediately after the actions taken. For the new configurations to take effect, restart your smartphone. After this, the iTunes Store should work smoothly on any phone.

Why can't I connect to the iTunes Store on my personal computer?

What should I do if the iTunes Store does not work when I try to download from a personal computer? First of all, see if you have an Internet connection. If everything works, then try repeating the requests in iTunes several times in a row. Wait some time. The error may be a malfunction in the functioning of the online store itself. Just wait until the server fixes the problem. If you still can't connect to the iTunes Store after some time, you should look for other reasons for the error.

What else could cause this problem?

To resolve this issue, try a few more simple steps. Update iTunes to the latest version. Do this through the official website or through the program itself. Do not use third party resources. Disable your firewall. It may cause operational problems. If you cannot or do not want to disconnect, please add this store to your exclusion list. Try going to Internet Options. If you have proxy servers in your settings, remove them, and then try to access the iTunes Store through a direct connection.

The last thing you should check is the hosts file. It is saved in a folder located at C:\WINDOWS\SYSTEM32\DRIVERS\ETC. Once you run it, you will see the IP addresses. Find the line 127.0.0.1 localhost, and then delete all addresses below it. Next, close and save the data to a file.

Finally, scan your PC with an antivirus. It is worth noting that all the above actions will not affect the data on your phone in any way. All files, without exception, will be saved on your iPhone safe and sound.

What to do on a Mac computer?

The firewall on Mac OS is configured to automatically accept incoming connections from Apple programs. If you have changed the factory configurations, you will need permission for external connections. If you still can't connect to the iTunes Store even if you have it, clear the cache of accepted certificates.

To do this, open Finder. From the menu at the top of the screen, click Go, then Go to Folder. In the search, type /var/db/crls/. Click on the “Go” button. Delete the crlcarche.db and ocspcache.db files. If necessary, write the administrator password. Restart your computer, then try connecting to the iTunes Store.

Before doing the above steps or going to a technician for help, carefully examine your modem. If the Internet is functioning correctly, then try logging into your Apple ID, then restarting your computer and checking the AppStore servers. Sometimes it is enough to log out of your account and enter all your login information again. As a rule, this helps to improve the operation of the store and fix the problem, as well as save time.

The above tips will also help in dealing with other similar problems:

iTunes Store does not connect and displays an unknown reason;
you sent a request, and the system asks you to repeat it after some time;
you receive a notification that something is wrong with your Internet connection;
I couldn't log in because the network connection was not established.

Try to figure out the problem yourself, and only then take your smartphone to a service center.
