My mobile phone shows arrears, and then I want to check the balance after recharging, but the information can't be sent out.

This situation should be that the phone bill has not arrived, or you owe too much, and the money charged is not enough to make up the arrears. The mobile phone card is still down, and the information cannot be sent out! Since you can surf the Internet, which means you have Wi-Fi, you can check the software. China Mobile, China Unicom and China Telecom all have their own exclusive apps. Next, you can check the balance by registering and logging in, and you will know why!
