The use of the Tablet PC can provide a backup mode of communications when a cell tower isn’t available. In order to use this mode of telecommunications, a WI-FI connection is required, however.
Another advantage of having this mode of telephone connectivity is the ability to make international calls far more affordable than using a cell phone. This is true even when you are on the road.
Messaging is done by email and provides a voice recording of the message when your phone is not connected to the Internet. You have telephone messaging support right there on the Tablet PC along with your Internet phone.
