I am a user in Jilin and Yanji. My 3G subscription expires at the end of the month. I want to upgrade my 4G package. Why can't I go to the business hall to upgrade online?

The reasons why China Unicom's 2G/3G users can't switch to 4G packages 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, you still can't handle it. You can contact Unicom customer service for details.
