I just canceled a mobile phone card with China Unicom. After I canceled it, I called again. They said it was out of service. Wasn’t it an empty number? What a shutdown. .

When you cancel your mobile phone card at China Unicom, the mobile phone card will be stopped, which means that the card will not be able to make calls, send text messages or use data to access the Internet. If you try to use a stopped SIM card, you will hear an outage or unavailable tone, which is usually not an empty number.

After canceling the mobile phone card in China Unicom, it usually takes a while to actually cancel it, which depends on the type of your mobile phone card and your specific situation. While waiting, you can check the status of your mobile phone card through the China Unicom customer service hotline or online business hall to determine whether it has been cancelled.

If you need to use the mobile phone number again, you need to wait for the cancellation process to be completed, then apply for a new mobile phone card and activate it.
