What's the matter with Apple's phone automatically hanging up when calling?

First, the reason for automatically hanging up:

1, accidentally hit the hang-up key during the call.

2. The network signal is unstable and weak.

3, caused by the failure of the mobile phone SIM card.

4. The internal system file is damaged or lost.

5. Hardware problems.

Second, the solution for Apple's mobile phone to hang up by itself:

1. Sometimes when the signal is bad in some places, you will encounter such a problem. If the call fails, you need to redial somewhere else.

2. After eliminating the signal problem, you can try to restart the machine. You can press and hold the power button of iPhone, and when the power off option appears, you can turn it off by sliding.

3. If restarting can't solve the problem, you can try plugging the mobile phone card again. You can pick up the card by using the card pick-up pin or other similar items that came with the iPhone. Then, there is a small hole on the right side of the iPhone, which is specially used for taking cards. You can pop up the calling card with the card taking pin. After you take it out, clean the phone card, put it back, and finally try again to see if you can make a phone call.

4. Restore network settings.
