Why does the mobile phone always hang up automatically when making a phone call?

If you use a vivo phone, the phone will automatically hang up when you make a call. You can refer to the following troubleshooting methods:

1, misoperation during the call.

If the phone is far away from the ear during the call, it will light up, and your finger or face may accidentally touch the hang-up button and hang up the phone.

2. Mobile phone card failure

If the mobile phone card is cut open by hand, the call may be interrupted due to irregular shape and poor contact. It is recommended to bring your personal ID card to the operator's business hall to apply for a standard mobile phone card. If the mobile phone card is dirty or oxidized, it will also lead to poor contact. It is recommended to keep the mobile phone card clean.

3. The operator's network is abnormal

Bad cell phone signal may cause call interruption, so it is recommended to make a call in an area with good signal. If the call is interrupted in the same place, it may be caused by an abnormal network in this area. I suggest you try again somewhere else.

4. Operator restrictions

If the call duration reaches 1 or 2 hours on the hour, it may be limited by the operator, so it is recommended to consult the operator.

The contact numbers of the four major domestic operators are: 10099 (China Radio and Television), 10086 (China Mobile),10 (China Unicom) and 10000 (China Telecom), so you can call them in time.

5. It is recommended to open VoLTE HD calling service (contact the operator to open it).

If the local 2/3G call network environment is not good, it is recommended to contact the operator to open VoLTE HD call service and try again. When the VoLTE function is turned on, the HD icon will be displayed in the signal bar.

6. Other network reasons

If the call with the fixed person is interrupted, it may be that the other party's network signal is abnormal, or there is something wrong with the other party's call equipment.

7. Upgrade the system

Please upgrade your system to the latest version, and then use to view.

8, service center testing

If the above methods fail to solve this problem, please back up the mobile phone data in advance, and take the mobile phone and purchase voucher to vivo customer service center for testing. Address of customer service center: Go to vivo official website /vivo Mall APP-My-Service outlets/after-sales outlets-select provinces and cities to inquire about the address of customer service center;

Tips: It is recommended to bring relevant purchase vouchers (such as purchase invoices/warranty cards/ID cards) when you go, and call the service center staff in advance to ensure that the staff will go again during normal working hours, avoid running empty, and pay attention to safety on the way back and forth.
