Can China Mobile change the package first and then deduct the fee?

In view of the different business rules and tariffs in different provinces, you can call local 10086 for consultation. Take Henan Mobile as an example: the package fee is deducted by the day, and the high one is charged according to the usage.

If the usage is small or not used, in order to ensure that the package fee can be charged within one month, you will not be suddenly stopped because of one-time charging or supplementary charging of a large amount of package fee, and the package fee is still charged by the day.

The change of 4G package will take effect immediately, and the old package will no longer be charged, while the new package will be charged by the day. This month's bill will show the old and new packages and their usage fees.
