My 4g network was shut down because I didn't know how to connect.

If you mean that the mobile phone can't access the Internet normally, please check the following:

1 Check whether to upgrade to 4G package, and it is recommended to restart the mobile phone (if 4G was upgraded last month, it will take effect this month, and you need to restart the mobile phone to access the Internet normally);

2 confirm whether there is a network, and suggest you use it where the signal is strong;

3. Check whether there is any phone bill in the account. If the balance is insufficient, it needs to be recharged before it can be used;

4. Confirm whether the parameters of the mobile phone have been set;

5. Check whether the USIM card is inserted. If it's plugged in and still doesn't work, it's recommended to go to the business hall to check whether the USIM card is faulty or change the card for testing.

Check whether there is something wrong with your mobile phone. I suggest you change your mobile phone for the test.

If your mobile Internet access reaches its peak in the current month, the system will automatically turn off your data functions such as Internet access, MMS and mobile newspaper, and will automatically turn it on next month.

If the above situation is still unresolved, you can contact the local manual customer service for handling.
