How to cancel the unwanted Unicom mobile phone card? Must I go to the place where I bought it?

You can go to any Unicom business hall for cancellation, and you don't need to go to the business hall for card cancellation.

Moreover, you can't just dial 100 10 to cancel the number. If you don't want to use this mobile phone number, you need to go to the business hall to cancel. If you don't want to use it for the time being, and there is no special agreement on your mobile phone number, you can stop it through the business hall or customer service, but you need to pay.

You need to bring your ID card to Unicom's business hall. Generally speaking, you should stop the machine first and then cancel the number one month later.
