If you are Unicom's mobile phone number, you can check the local phone number in the following ways:

1. This machine uses caller ID to dial other mobile phones for inquiry.

2. This machine calls the local customer service hotline 100 10 for manual inquiry.

3. The owner himself holds the original valid certificate to handle it in Unicom's own business hall.

Tips: As the inquiry methods of major operators are different, it is suggested that you can directly contact the customer service of the corresponding operators for specific inquiry.
