When the telecom card is shut down, it becomes an empty number, and it cannot be received, typed, received or sent short messages. Why is this and how to solve it?

Dear telecom users, hello! Thank you for your support to Telecom!

According to your description: Have you set up call forwarding or other services? Just cancel. Make sure the phone is not in arrears. You can use other phones to call customer service. After confirming your identity, ask the staff to help you check your recovery.

Wish you a happy life!
