How to cancel the main card and the auxiliary card?

If it is necessary to cancel the secondary card, the secondary card user can bring a valid certificate to the local business hall to cancel the account. Due to the different policies of different cities, some cities need to access the internet for a certain period of time before they can cancel their accounts. Specifically, you can contact the Unicom customer service to which the number belongs, subject to local policies.

If you want to cancel the Internet access function of the secondary card, you can turn off the Internet access function in the phone settings. For example, for Android phones, you can turn off the internet access function in phone settings > wireless and network > mobile network.

> if the data is enabled, you can cancel it by ticking, or you can refer to the mobile phone manual. If the mobile phone does not support this function, you can also call the local customer service hotline 100 10 to cancel.
