I used a 58 package for my card in Xiaogan, Hubei Province. How do you charge if the GSM user's traffic is exceeded?

generally, at the beginning of the month, the package fee is deducted in one lump sum, or the corresponding fee is deducted according to each call time, and then the settlement time and traffic time at the end of the month are deducted only for the excess part of the package fee. Generally, it is calculated at 3 angles and 1MB.

If you are afraid of traffic overload, you can use Tencent Mobile Manager to set the traffic monitoring function, which is very useful.

its online management: real-time statistics of traffic, timely reminder of excess, so that you know the online traffic like the palm of your hand;

the networking firewall function says no to sneaking networking programs to avoid traffic loss.
