Unicom 3g calls and sends text messages.

If your mobile phone can't surf the Internet normally, please check the following:

1 After upgrading to the 4G package, if you don't restart your phone, you can't use the Internet function 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, I suggest you go to the business hall to check whether the USIM card is faulty or not.

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

The above situation has not been solved, you can contact the local manual customer service to handle it.
