Unicom 3g card can make phone calls and send text messages, but it can't surf the Internet. What should I do?

Reasons why mobile phones can't surf the Internet normally:

1. Check whether the mobile phone is in arrears. It is recommended to pay for recharge in time.

2. Check the signal situation in the area, and it is recommended to use it where the signal is strong.

3. Check the mobile phone settings, and suggest resetting the 3G network access point to 3GWAP.

4. Try to try another mobile phone. If you can't get online, you can go to the local business hall for inspection.

5. If the above possibilities are ruled out, it is suggested that you call 100 10 for manual customer service to check whether the online status of your mobile phone is normally opened.
