This depends on the package you are subscribed to and its service contract. If you are subscribed to an Internet package which has a download limit, after exceeding such limit you will either continue using the Internet at an additional charge, or else your Internet speed will be automatically slowed down. Such information should always be listed in your contract. Alternatively, if you are a heavy Internet user engaging in various online activities, you will most probably require an Internet package which has an unlimited download limit together with an adequate Internet speed which supports your usage pattern.
