If you bought a brand new iPhone, cut the card according to the instructions, but the phone does not see it, most likely the problem is in the old chip revision. Usually very old SIM cards suffer from this.

Solution: The problem can be solved by going to the customer service center. Usually the SIM card is replaced with a new one for free or for a symbolic amount. The procedure takes from several minutes to an hour.

Reason 2: Incorrectly cut/damaged SIM card

You bought an iPhone, but before that you used a phone with a format card mini SIM. Armed with instructions and scissors, you cut it, inserted it into your smartphone, but it doesn’t see it. Most often this happens due to improper cutting or damage to the chip during this procedure.

Solution: Same as in previous paragraph: going to the service center of the company providing communication services and replacing the SIM card with a new one.

Reason 3. Locked iPhone

Many iPhones sold at discounted prices by small shops and private owners are “gray” (imported unofficially). Usually main drawback Such phones lack a full manufacturer’s warranty, but sometimes it happens that operator versions of smartphones tied to some Verizone or AT&T end up on the shelves. Sellers carry out unlocking and untethering, but sometimes it fails. In such iPhone case does not see the SIM card or cannot catch the network if it belongs to a “foreign” provider.

You can check if your iPhone is locked to an operator using special service. Among them there are both free (the accuracy of the determination is not always guaranteed) and paid (usually the service costs 1-2 dollars). If the site reports that the smartphone is locked to an operator, this is the reason why the SIM card is not visible.

Solution: Sometimes telecom companies perform unlinking for free, but the procedure is quite complicated and bureaucratic. Sometimes you need to provide documents confirming the purchase, have SIM of that operator, but sometimes everything is simpler (for example, with AT&T): you just need to submit an application on the official website. You can also unlink your iPhone from your operator using a special online service. But such services usually cost money (from 1 dollar to 100 or more, depending on the complexity of the case), and no one is immune from scammers.

Sometimes the reason for losing connection with a SIM card is a broken contact in the SIM tray. The card may come off if dropped, especially if it has previously been trimmed by hand. Even a slight loss of elasticity by the contacts on the board (due to the fact that the card was often taken out of the slot) can also lead to such consequences.

Solution: Remove the tray with the SIM card and see if it is positioned correctly. If there is any offset, correct the card and carefully insert the tray. If the SIM card “walks” around the slot (too much plastic was removed during trimming), it is advisable to replace it, since accidentally closing the contacts with a displaced SIM card can damage the communication module.

Reason 6. iPhone is physically damaged

At iPhone falling, water getting inside, using low-quality charger and other violations of the rules of its operation are not uncommon physical damage apparatus. Among them are short circuits, failure of chips and wiring elements on the board, burnout of diodes or resistors and other minor defects.

If the SIM card is known to be working (works in another smartphone), the iPhone is official, the firmware is OK, and the tray is like new, most likely the smartphone is physically damaged. Only a service center can accurately determine the cause and eliminate the defect.
