In addition, there are other reasons why you can't change the package:
Taking 3G users as an example, the reasons for unsuccessful 3G package changes are as follows:
1. The mobile phone has expired and cannot be replaced;
2. The package has been changed in the current month;
3. The mobile phone is in an abnormal service state such as number protection and loss reporting, or is a blacklisted user;
4. From the last day of the month to the beginning of the month, it may affect the use of the package change business;
5. The package cannot be changed from 00: 00 to 24: 00 on the last day of the month;
6.2G prepaid users cannot handle 3G services in the online business hall;
7. The original mobile phone package does not support changing to 3G package. For example, if you participate in Unicom's contract plan, you can only switch from flat package to high package during the contract period, but you can't successfully switch to low package.
If 2G/3G users can't upgrade the 4G package, the reasons are as follows:
1 network card user;
2 group member users;
3 users with contract plan restrictions;
4 From 0: 00 on the last day of each month to 8: 00 on the following month 1 day, old users of 2G/3G cannot apply for 4G packages temporarily.
5. Other special circumstances (such as number arrears, abnormal use of blacklist, missing user information, etc.). );
There are other restrictions that make it impossible to handle.
Excluding the above reasons, it still can't be handled. Please contact local customer service for details.
