The newly activated network card can receive short messages but can't surf the Internet.

The mobile phone can't surf the Internet. Please check the following:

1. Confirm whether there is a network. It is recommended to use it where the signal is strong;

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

3. Check whether there is something wrong with the mobile phone. I suggest you change your mobile phone to check it.

4. Check whether there is phone bill in the account. If the balance is insufficient, you need to recharge it before you can use it.

5. Confirm whether the phone parameters have been set.

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

The above situation has not been solved, you can contact Unicom's manual customer service to handle it.
