It often happens that after a longUsing your iPhone, it suddenly stops detecting the SIM card and starts displaying a message about its absence. Most often this occurs after the fall of the device or any of its sharp shakes. Oddly enough, this problem is not so rare on Apple devices. Do not be afraid: if your iPhone does not see the SIM card, this does not mean that it is broken, most likely it’s just a small program failure that is easy to fix.
The easiest ways to solve the problem
To start, it is recommended to try justRemove the SIM card and insert it into the device again. If this is a normal temporary failure, then this technique should help. If the iPhone does not see the SIM card and further, we try to reboot the device and check whether it’s possible to correct the error. If the problem is not fixed, then it is quite possible that the cause of the error is not the device itself, but the SIM card. Find another and try to turn on the phone by installing it. If your iPhone works with another card, feel free to contact your operator for a free replacement.
Software Changes
If the previous tricks did not bring results,and the iPhone does not see the SIM card as before, we try to solve the problem with the help of changes in the software. For example, you can make the firmware of the device. If the iPhone does not see the SIM card after the update - try to roll back the operating system to the previous version. Most likely, these methods will help you bring your favorite smartphone back to life.

Some manufacturers "sew" in your machinespecial binding to a specific carrier. The rest of the SIM card device simply does not detect. If your freshly bought iPhone is locked at the request of the company, then you have no choice but to return it to the store. Of course, you can purchase a special chip for the unlock, but it will still be easier to buy a device elsewhere that is not blocked for telecom operators. To avoid such problems, try to handle the smartphone more carefully, do not allow it to fall, get wet and download suspicious applications. Be careful.
