How can I know my mobile phone number if I can't send a text message or make a phone call?

You can try the following ways to check your phone number:

1. This machine dials the phone with caller ID enabled, and your number will be displayed on the screen of the other party's mobile phone;

2. If your number is not in the service area, you can call the local customer service number 100 10, and the customer service will check for you.

3. Generally, the mobile phone will write its own phone number after receiving the sim, which depends on the function of the mobile phone. For example, for iphone, you can select settings > phone to query.
