Why can't the existing bag be replaced with a new one? Can't you find out the deadline of the contract term?

1, the change of mobile phone package was unsuccessful. It is not excluded that the number is caused by the following circumstances:

1 Your mobile phone is in arrears and cannot be replaced;

You changed the set meal this month;

3 users with contract plan restrictions;

4. Your mobile phone is in an abnormal service state such as number protection and loss reporting, or it is a blacklisted user;

From the last day of the end of May to the beginning of the month, it may affect your use of the package for business exchange;

6 Other factors make it impossible to replace the package.

Excluding the above situation, it still cannot be changed. I suggest you consult the Unicom manual customer service to which the number belongs.

2. You can check the remaining contract period of your mobile phone number in the following ways:

1 Log in to the online business hall, click Self-help on the homepage, click the small avatar in the upper left corner after entering, enter the personal information interface, and then click "My Contract" to view it.

Log in to the online business hall/click phone bill inquiry > phone bill inquiry > account balance to view the frozen amount, that is, the remaining total amount awarded by your contract. Just divide the frozen amount by your monthly authorization, that is, your remaining contract period.

Tips: There are differences in business policies in different cities. The actual situation is subject to local policies. For details, please contact Unicom's manual customer service for consultation.
