Why can't I get the SMS from China Mobile Unicom customer service on my mobile phone?

Should I send a text message directly to the operator number or check the detailed list in the network hall?

There is a certain delay in sending messages directly to operators. It's normal not to receive it. Many people send it again, and operators can't handle it.

Check the detailed list in the net hall, and you will definitely receive it.

Do not resolve direct complaints. They will accept it.
