SIM Card Not Detected: A Common Problem

In fact, inability to detect SIM card is quite common after iOS upgrade. A few years ago, a major update when the iPhone 5s was released bugged thousands of iPhones, so Apple had to issue an emergency security update. even lasted 2 days. However, if solutions exist, for some users, resetting the network settings or removing and reinserting the SIM card does not help.

If after resetting the smartphone and it still shows "No SIM card", then check if the operator settings are up to date. It is possible that some of the operator files are not up to date, therefore the device cannot read the card. This problem is not always related to iOS 15 but also to other software versions. You can click "Settings" > “General” > “Information”. If an update is available, you can select from the menu "Ok" or "Update" to complete the update.

If the SIM card cannot be detected due to the system update, in general, it will not be a hardware problem. However, if a reset does not fix the problem, you can try swapping the SIM card to see if it is recognized normally. If in general, a simple restart is enough, this is not always the case.

In any case, the problem is not serious, there is no need to worry about it. It is simply an inconvenience for users but which, knowing Apple, will be quickly resolved.
