A telecom mobile phone card forgot its mobile phone number, and now it is overdue. You can't even call or text. How can I know my mobile phone number?

1. Now most mobile phones have the number where you can find the mobile phone card. Look for it in the SIM card management.

2. If you can't find the mobile phone card number in the SIM card management of the mobile phone itself, call the customer service number of Telecom 10000 to ask the manual customer service, but it seems that you need to register your name or ID number.

3. If you don't register your name or ID number and the customer service doesn't give you the number, then go to the business hall and ask;

4. If you need to know the number because you don't have a real name to register your name or the ID card customer service doesn't give you the number, you should make up the phone bill and call out to have a look.

However, you can usually call customer service at 10000, at least in the business hall. In addition, under normal circumstances, the mobile phone number of telecom is registered with the real name of ID card, so don't worry that customer service won't tell you the number.

Good luck.
