Iphone4 SMS does not display the name, what should I do?

China Telecom's American mobile phone has no card slot, which is used for burning numbers. There are many problems with this model. 1. The dialing number is Yes, which means that you have not made an international call and cannot dial. Solution: Settings-Phone-Turn off Dialing Assistant-OK. 2. Keyboard dialing can make phone calls, but you can't dial directly from the address book. Solution: Add +86 before the phone number. Don't directly store the number dialed by others. You should create a new contact and automatically add +86 after saving. 3. Send a short message with the name of the recipient, but receive a letter without the name. Solution: For each number, save two numbers, one with +86 and one without, Ok. 4. How to turn off automatic screen rotation? Solution: In the lock screen or standby turntable, touch the taskbar or the bottom of the screen with your finger, and drag it up to bring up the control panel toolbar. Click the last in the first row to close. 5. The installed software will automatically shut down when it is turned on. Solution: Settings-General-Restore-Restore all settings.
