Is there a short message on the telecom card and no signal?

Mobile phone failure is a common problem, but many people don't know how to solve it. This article will introduce several solutions to help you easily eliminate cell phone signal problems.

Check cell phone signals and phone bills.

First, check the cell phone signal and phone bill. Look at the name of mobile, Unicom or telecom service provider displayed in the upper right corner of the mobile phone. What is the signal strength? Is it because of the arrears or the SIM card is not inserted properly, which leads to the shutdown?

Check the phone bill

Next, check the phone bill. Is it because of the arrears or the SIM card is not inserted properly, which leads to the shutdown? If this is the problem, then you only need to recharge or re-insert the card to solve it.

Restore factory settings

If there is nothing wrong with the above, there may be something wrong with the system. Open the settings quickly and look for the "Restore Factory Settings" option! However, restoring the factory settings will erase all data in the mobile phone, so be sure to back up important data before operation.

Contact mobile phone after-sales maintenance

Finally, if all the above methods fail, please contact the mobile phone for after-sales maintenance! They will help you check the hardware and software of your mobile phone, find out the problems and solve them.
