1. 如果您是联通的手机号码用户，想要申请销户，可以通过以下途径进行操作：首先，登录中国联通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.
