Some national service providers that have coverage in many areas may charge roaming charges when you travel outside an established home area. Long distance charges may also apply to calls you place. These are typically in places with low service demands. If you travel a lot, or want to use your phone in more rural areas, you might consider getting analog service or a DualMode or TriMode phone that will allow you to take advantage of the analog networks that blanket most of the country. E-mail, Messaging and Other Wireless Data Services Wireless digital technology has not only enhanced cellular phone service, but was opened up a whole new arena of wireless data services, too.
Wireless data is transmitted using the same transmission networks as phone calls.
The ability to transmit data through the air with as much ease as transmitting data through phone lines and cables is continually improving and increasing. Nearly anything that can be put in a digital format can be sent over these same transmission networks. Wireless digital networks do that. As work force and consumer mobility increases, so does the demand to have instant access to information via fax, e-mail or other means, regardless of time or location. Today cellular phones and wireless devices are available that allow users to send e-mail and faxes, send and receive short messages and access the Internet.
