I went to the Unicom business hall to cancel my account. I was told that I can only close my account in advance now, and I can't officially close my account until next month 10.

If you are a post-paid user of Guangdong Unicom, after you go to the local Unicom business hall for pre-cancellation, you will automatically cancel the account if there is no arrears after the third billing month. Therefore, after making an appointment to close the account, as long as there are no other circumstances, the account will be automatically closed at that time, and there is no need to go to the business hall. Please consult local customer service for details.
