I can't remember my cell phone number. How to check?

If you use Unicom's mobile phone number and forget it, you can query it in the following ways:

1. This machine calls the local Unicom customer service hotline (100 10) and turns to manual service to check the number of this machine.

This machine calls other mobile phones with caller ID to check their numbers.

3. The owner himself holds the original valid certificate to inquire at the local Unicom's own business hall.
