You can cancel, but you must have the original ID card of the account holder, the authorization letter for account cancellation signed by the account holder and the original ID card of the person. To handle the account cancellation business, you need to bring a valid ID card to the business hall. The first pre-deposited phone fee must be consumed when you access the network, and the account cancellation business can only be handled when there are no other activities or special agreements. After formal account cancellation, pre-deposited phone charges can be refunded, but prepayments, grants and one-card recharge charges cannot be refunded. Special reminder: Individual users must provide the original ID card of the account holder, and corporate users must provide company certification, a copy of the business license with an official seal, and a valid ID card of the person in charge.
