Telecom's mobile phone, suddenly, can only surf the internet, can't make calls and send text messages, and others can turn off their phones and call customer service. What happened?

Hello, first of all, thank you for your support to China Telecom. According to your description, it may be that your mobile phone is in arrears. You can log on to the online business hall-self-service-phone bill inquiry-balance inquiry to inquire about your account balance. If the balance is insufficient, you can enter the recharge payment-enter your own recharge times and amount-select the payment method-recharge according to the page prompts.

If you need to check the bill and pay the phone bill, please go to the online business hall of Anhui Telecom. Wish you a happy life!

I hope my answer will help you and be adopted by you!
