Telecom mobile phones can only use telecom cards to surf the Internet, and can't send messages, receive messages or make phone calls.

Hello, first of all, thank you for your support to China Telecom.

According to your description: answering the phone and sending text messages are essential functions of a normal UIM telecom card, so first of all, you can judge that there may be something wrong with your mobile phone card, or that the mobile phone cannot recognize the mobile phone card;

Telecom mobile phones can access the Internet, that is, the mobile phone itself can connect to the WIFI network. If restarting still doesn't solve the problem, you need to consider changing the card first.
