Generally, all carriers work equally well in large cities or major highways. But, when traveling to more rural areas of the country, some frequencies work better than others. Here's a brief description of the five types of cell phone frequencies, their pros and cons, and which service provider uses them:
Typically, these are "older" carriers who began their service when cellular technology was conceived. These carriers tend to be better established with more towers and roaming agreements than "younger" wireless competitors. Both Cingular and Verizon provide dual bands in their phones and service.
These carriers focus a good part of their coverage to populated areas, such as cities and highways. Sprint PCS is an example of this type of provider.
This provider offers only one digital band for its network. This means that the carrier can only receive and transmit PCS frequencies. The network does not support Analog. T-Mobile is an example of a PCS Band only provider.
Major carriers often have roaming agreements with these types of providers for cellular service in rural areas. These carriers rely on their original Cellular Band and provide dual band phones for Digital roaming.
Coverage for these carriers are usually limited to well populated areas. This provider is not recommended for use in rural areas. Nextel Southern Linc and Mike are the cellular phone service providers currently using this system in North America.
