What if the network connection is abnormal?

If the mobile phone network connection is abnormal, troubleshooting can be carried out according to the following conditions:

Situation 1, the contact between the SIM card and the metal contact of the mobile phone is insufficient. Try to insert the SIM card again.

In case 2, if the SIM card is damaged or the mobile phone has a problem, you can change the machine to check to see if there is a problem with the SIM card or the mobile phone.

In case 3, the current position is a signal blind area or there is no signal suddenly. You can test in another place and pay attention to the normal signals of other users around you.

Case 4: If the mobile phone card is in arrears, you can pay the arrears and start the mobile phone.

In case 5, the service is suspended due to the abnormal use of the number, for example, the code is used for illegal or illegal activities.

In the sixth case, roaming in Taiwan, Hong Kong and Macao or roaming abroad can only be used after roaming in Taiwan, Hong Kong and Macao and international roaming are enabled.

Situation 7: When the total traffic generated by surfing the Internet in the current month reaches the upper limit of the package traffic, the system will automatically turn off the internet access function, or the speed-limited network will automatically resume opening every month, depending on the upper limit rules of your package traffic.
