We specialize in 3G4G wireless routers that support AT&T, Sprint, Cricket, Verizon, Clear, Alltel, Virgin Mobile and many other carrier air cards or modems. For the most part, these wireless USB routers are plug and play, regardless of operating system, compatible with Windows, Mac, Linux, or whatever. As a rule, if the equipment you have has wi-fi capability, it will be compatible with most routers. A few of the Cradlepoint routers support over 200 different modems or cellphones, both 3G and 4G. br br Visit : br Address : P.O.
