  2. Smartphone applications and software may automatically communicate via the Internet, and the resulting packet transmission will be charged accordingly.
  3. Incoming calls received abroad are charged to the customer as well as the caller.
  4. Calls are timed and charged from the moment when SEND is pressed in some countries/regions. In such countries/regions, therefore, calling charges are charged even when calls fail to be connected.
