Apple 4s has been saved, caller ID has been turned on, and SMS can be displayed. Why can't I display the caller's name? Didn't you escape from prison?

The dialed call name may be caused by a problem with the dialing software or system; The solution is as follows:

1, you can try to restart the phone to solve the problem, and it will return to normal after restarting.

2. If you can't solve the problem by restarting it many times, you can try to restore the mobile phone system to the factory setting state to solve it.

3. If the user is using the US version of iphone, the name of the caller will not be displayed without +86 in front of the contact number; However, after adding +86 before the contact number, the caller's name will be displayed, but SMS is not realistic. The solution is: open the appstore, search for the number assistant app, download and install it on the mobile phone; After the installation is completed, open the app and click the country code (+86) of the software. All numbers in the address book will be preceded by "+86"; Click the country code (+86) again, and all the numbers in the address book will be removed from the front "+86"; Finally, click the "coexistence of the above two" option, so that each contact has two numbers, one with +86 and the other without+86; Through the above settings, the problem of name display of incoming calls and short messages can be solved perfectly.
