Huawei mobile phones always display networking errors. Please check whether the network is still working properly. What happened?

If the mobile phone can't surf the Internet normally, 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 it in another place and pay attention to whether the cell phone signals of other users around you are normal.

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 abnormal number use, such as the number being 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 package traffic capping value, the system will automatically turn off the Internet access function, or the speed-limiting network will automatically resume opening next month, depending on the traffic capping rules of your package.
