Mobile phones can't surf the internet, but they can make phone calls and send text messages. The mobile phone is fine.

If your mobile phone can't access the Internet, you can usually troubleshoot it in the following ways:

1. If you don't restart your phone after upgrading to the 4G package, you can't use the Internet function normally;

2. Confirm whether there is a network. I suggest you use it in a place with strong signal.

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.

6. Check whether there is anything wrong with the mobile phone. It is recommended that you change the machine for testing.

7. If the traffic is capped, it will also lead to the inability to access the Internet.

If the above situation has not been solved, you can contact the local Unicom manual customer service for processing.
