Apple's mobile phone can't make calls, but it can receive text messages. What happened?

The following conditions will prevent the phone from dialing:

1. The other party's phone number is wrong, or the other party's number is down or cancelled.

2. Mobile phone hardware problem, the communication module is about to be damaged.

3. Software problems, program errors caused by jailbreak.

According to different situations, the corresponding solutions are given:

1. Check the other party's number carefully, especially the slight differences, enter the correct number and try again.

You should go to the after-sales warranty immediately. During the warranty period, the Bank of China and the banks in Hong Kong can replace the new machines free of charge, and the rest can be replaced with payment machines (shanzhai, demon machines and black machines will be handled by themselves).

3. Firmware should be updated. Generally speaking, dialing under genuine firmware can't go wrong unless there is something wrong with the genuine firmware itself.
