How does the master number cancel the signed family payment slave card?

The steps to release the slave number from the master number are as follows:

1. Log in to Unicom's mobile phone business hall with the main number, and click Services > Payment > Home Payment;

2. Select the slave number that successfully signed the contract, slide to the left, click the "Delete" button to cancel the contract, select the effective time of the cancellation (effective immediately or at the end of the month), click "OK" to indicate that the cancellation is successful, and the master and slave numbers receive the SMS that the business has been successfully processed (sending SMS is not supported temporarily when the slave number is fixed line or broadband).
