I want to change the set meal and say that the contract has not expired. What do you mean? How to check your contract period?

The contract plan refers to your participation in Unicom's preferential activities, such as handling Unicom's prepaid phone bills to send mobile phones, buying mobile phones to send phone bills, saving one to get three benefits.

If you need to query the expiration time of the contract, you can judge it by querying the remaining time of the contract. The query method is as follows:

1. Log in to the online business hall /sAbMM
