The existing contact names in the address book are not displayed in the SMS and call records of iphone4s Hong Kong Bank. Only the content imported from the SIM card can be displayed.

I come from 4S, just like you. Text messages and phone records do not show names. I visited folk experts all over the world, tried more than a dozen ways, and finally got my wish. The root cause is that the third-party address book conversion software (such as qq address book synchronization software) has changed the system parameters. So the solution is simple. First of all, you should import the address book of the original mobile phone (non-4s) into outlook on computer A (different mobile phone systems have different import methods, and there are many on the Internet. I used to be Dopod S700, WM system, which is easier to synchronize to outlook address book). Then synchronize 4s and Itunes backup applications on computer a (don't synchronize outlook). Then connect 4s and Itunes on computer B and select Devices-Summary-Restore. Restore the mobile phone to the factory system state. Then sync 4S and computer A in Itunes, device-information-sync address book (with outlook), and other applications can also be synchronized together. Try again after synchronization, and everything is done! When synchronizing the address book in the future, try to use the address book address provided by Itunes, and do not use the third-party address book conversion software, otherwise the system will be restored again.
