(3)  Traffic control capability and usable applications
For cases such as ordinary Web browsing, this is a trouble-free data service that makes maximal use of the high speed provided by EV-DO.

If a large amount of data is sent or received when the local network is congested, transmission speed will be controlled automatically, to prevent excessive load on the network. Also, if an unusually large amount of data is transmitted within a certain time, connection may be interrupted.

There is no restriction on transmission protocols or usable applications.
