Shi Sheng Pass displays a grid error. We can follow the following process:

Step 1: If you can't access the Internet, please try to turn it off, turn it on, and restart it, and check whether it has reached the threshold of this month's traffic capping and whether the mobile data set by the mobile phone has been turned on; The mobile phone sets the mobile data option APN and whether the name is set to 3gnet.

Second, check whether the account still has phone bills, and the balance is insufficient and needs to be recharged before it can be used;

Fourth, check whether the USIM card is plugged in. If it's plugged in and still doesn't work, I suggest you go to the business hall to check whether the USIM card is faulty or not.
