My iPhone 5s worked great. I changed the SIM card and reset the iPhone, after which the error “SIM card is invalid” appeared. The problem repeats with different cards, the phone does not want to go through activation.

Hello, Pavel.

The problem is quite common, Apple is aware of the possibility of its occurrence and recommends doing it a certain sequence actions.

1. Make sure that the SIM card is not blocked, is activated and has an active tariff plan.

2. Update iPhone to latest available version iOS.

3. Enable Airplane mode on your device and turn it off after 10 seconds.

4. Restart iPhone.

5. Check that the SIM card is installed correctly.

6. Restore firmware on iPhone via iTunes.

If it doesn't help

An error like this often occurs during iPhone activation or after updating the firmware on the device. It can appear in one of three cases:

1. The SIM card itself has failed

Yes, this happens.

It’s very easy to check: insert the problematic card into another device and/or another card into this iPhone and the version with the SIM card not working is no longer available.

2. The SIM card receiver has failed

Sometimes this happens in the process using iPhone, especially for those who often change cards on the device.

If, before activating the iPhone, the indicator displays cellular network and the problem itself arose precisely during activation or flashing; most likely, the problem is not in the SIM card receiver.

3. iPhone is locked to another operator

Oddly enough, this is most often the cause of the error. The smartphone was brought from another country and was locked to a local operator.

For use with domestic SIM cards they could be used special devices, called Turbo-SIM. This is a miniature board installed in the SIM card tray. It helps activate a locked iPhone on any SIM card.

It could have been inadvertently removed along with the SIM card with which the iPhone worked.

If there was no Turbo-SIM, it is not a fact that the smartphone is officially unlocked. It could have been unlocked in a non-official way.

There are ways to enter smartphone data into the operator’s database, allowing the device to work with the SIM card installed at the time of unlocking; when you change the card, such unlocking is lost.

SIM card - main element, without which, in principle, a mobile phone itself is not needed: without it, calls, sending and receiving SMS messages, and “gatherings” on the Internet are inaccessible. However, buying such a mini-card is not enough for pleasant smartphone use. Although rare, there are cases when the SIM card fails. Moreover, it is unknown whether this is happening because of the phone itself, or whether the culprit is the SIM card. What is obvious is that there is a problem, because it is not for nothing that the phone displayed the inscription: “Error when registering a SIM card.” What to do if such a situation arises? This article will be the answer.

What to do?

Simka fails at the most unnecessary moment. How to fix the situation faster? What to do in such cases? Perhaps the following instructions will help:

  • First, you should open the phone cover and inspect the SIM card for the correct location in the slot. Most likely, the card is simply installed incorrectly or is slightly shifted: as a result, the error occurs. If the design of the phone means installing a SIM card under the battery, and not in a special slot nearby, then perhaps the contacts of the SIM receiver and the SIM card itself simply do not touch. To solve the problem, you should fold a sheet of plain paper in several layers and place such a blank between the SIM card and the battery, and then assemble the phone. It is quite possible that pressing the SIM card with paper will allow contact to be established between the parts, and the SIM card will start working again.

  • The problem is not solved? We should move on! Next step- This is an inspection of the SIM card and receiver for any contamination. Perhaps contact between them cannot be established only because of some stains or blots. If this is really the reason, then a regular eraser will correct the situation. They need to be wiped gently visible contacts. After that, all that remains is to install the “stuffing” of the phone in place and check the SIM card for functionality.
  • And it didn't help? We need to act further! So, you can try to pull out the SIM card and bend it a little so that the side with the contact is convex. Perhaps this method will become a “circle of salvation.”
  • If all these steps do not produce results, you can try installing another card in your phone. Better than a different operator altogether. If it works, then the whole problem is with the previously installed SIM card. Otherwise, you need to look for the reason in the phone itself.

The culprit of the problem is the phone

To help quickly solve the problem with registering a SIM card, you should consider the main reasons that contribute to the error occurring due to the phone:

  1. Some phone models are made to accommodate cards certain operators communications. This means that attempts to install the SIM card of their competitors will be in vain.
  2. Errors often occur in phones with two SIM cards. So, in some models one SIM card may refuse to register while another is working. To check whether this is really the reason, you should insert the questionable card into both slots one by one.
  3. Various mechanical and physical damage the smartphone itself. For example, the entry of water or steam into the device can cause contact failure due to its oxidation. You can try to solve the problem yourself by disassembling the phone’s internals and wiping them thoroughly. The problem is not solved? You should contact a service center for help.

Please note that the phone may not immediately begin to “glitch” due to a fall or moisture getting inside. Initially, it can function quite normally and only later begin to act up. Therefore, if an error occurs when registering a SIM card, you should remember whether it recently had to fall or float? Perhaps the reason is precisely such troubles.

The culprit of the problem is the SIM card

  • The expiration date has expired. Some operators simply block it if the SIM card is not used for a long time. As a result, it turns into a useless piece of plastic. A refusal to provide services may result from the operator due to the balance remaining at a negative level for quite a long time.
  • Have you just purchased a SIM card? Perhaps the reason is simply that it was not activated correctly. In this case, you should contact the seller for help.
  • Many modern smartphones Only allow installation of mini-cards. Some of their owners, deciding to save money and time, cut the SIM card themselves. If this is done incorrectly, then you should expect a registration error. Solution to the problem: buy a new card!
