If you can't change the package, there is no limit to the number. We recommend that you check the following reasons:

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, the old users of 2G/3G can't switch to the 4G package temporarily;

5. Other special circumstances (such as number arrears, blacklist and other abnormal use status, missing user information, stopped number or reported loss business);

6. There are other restrictions that make it impossible to deal with;

7. Reasons for system delay;

8. Has the package been removed (at present, some cities have removed the local combination package).

If the above reasons are eliminated, it is still impossible to deal with the above situation. It is recommended that you contact your local customer service department for details.
