3G Cellular data protocols have clearly revolutionized the wireless data sector and have become increasing pervasive not only in the business world but in many diverse industries. The speeds promised by these data protocols such as 1xEVDO RevA & HSUPA can easily be compromised by the quality of data card selected. Since RfWeL is an authorized dealer for the major U.S cellular carriers including AT&T, Sprint/Nextel, Alltel & T-Mobile we are in a unique position to objectively guide our customers on the most ideal data modem for their application. Below are some of the major datacard vendors who have branded datacards with these carriers.
