You can make a phone call, there is no arrears, and the traffic shows that the traffic is on, but you can't send messages or surf the Internet.

Hello, if your number is not in arrears, you can make a phone call, but the message can't be sent and you can't surf the Internet. It is recommended to check the following: 1. Confirm whether there is a 3G or 4G network. It is recommended that you use it where the signal is strong; 2. 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; 3. After turning off the phone for 3-5 minutes, restart the phone and try again; 4. 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. The above situation has not been solved, you can contact the local manual customer service to handle it. thank you
