The signal of the telecom card is intermittent, so I can't make a phone call, send a short message or surf the Internet. Why?

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

According to your description: 1. The cell phone has a signal and can't answer it. The reasons may be:

(a) mobile phone failure;

(2) The UIM card of dual-mode mobile phone is inserted incorrectly;

(3) Blacklist and whitelist are set inside the mobile phone, so it is impossible to dial or connect personal numbers;

(4) The other party's mobile phone problem makes it impossible to dial.

Second, the treatment process:

(1) If you have other telecom mobile phone users around you, you can borrow their mobile phones to test whether they are normal. If it is convenient for you, you can also go to the nearest telecom business hall to change the machine and card for testing;

(2) If it is a newly installed user or a newly changed card user, you can go to the business hall to check whether the mobile phone card number is consistent with the card number in the system;

(3) If you use a dual-mode mobile phone, you can take out the card and confirm whether the telecom UIM card is inserted correctly.

(4) If only a few numbers can't be dialed when making a call, you can dial this number with other mobile phones first to see if you can dial it, so as to determine whether it is a problem with your own mobile phone settings or the other party's number. If it is a problem with your mobile phone settings, you can restore the factory settings to solve it; If it is the other party's number, you can prompt the other party to check the phone settings.

(5) If individual users can't dial your mobile phone, you can check whether your mobile phone has white list, black list and other settings, or you can directly restore the factory settings to solve it. Anhui Telecom will serve you wholeheartedly, and I hope my answer can be adopted by you.
