1. 如果您是聯通的手機號碼用戶，想要申請銷戶，可以通過以下途徑進行操作：首先，登錄中國聯通APP，然后 navigate to the 'Service Model' option, within the 'General Services' section, and select 'Appointment for Account Cancellation' to initiate the process for number cancellation. 2. Alternatively, you may personally visit the nearest designated China Unicom self-service counter with a valid original identity document to handle the cancellation in person. 3. For those who wish to cancel their account from a different location, be advised that the account holder must be present for the cancellation process; it cannot be done by proxy.
