How to check the local telephone number?

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

1. This machine dials the local Unicom customer service hotline (100 10) to manually 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 and goes to his own business hall of Unicom to inquire.
