Where can I find Huawei's mobile phone number?

If you use Unicom's mobile phone number, if you don't know the local mobile phone number, you can query it in the following ways:

1. This machine uses caller ID to dial other mobile phones to check its number.

2. This machine dials the local Unicom customer service hotline, and then manually inquires the machine number.

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