Why didn't you receive the SMS notification when you changed the 4G package?

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.

You can also log in to the online business hall to check the upgrade status. Home-Business Processing-Upgrade 4G- Upgrade 4G Status Query.
