Do cell phone signal boosters work on GSM mobile networks?

Yes, our LTE cell phone signal boosters work with all cellular telephone technologies and networks used in North American USA & Canada, including 4G LTE. The only exception is that of Push-to-Talk (PTT) networks which is one wireless telecom service platform that is being phased out already. Basically all our 4G signal boosters are GSM signal boosters because they cover 698 MHz to 1755 MHz frequencies and bands that encompass the GSM network being used by several mobile service carriers in Canada and United States. Furthermore, those frequencies also cover other wireless networks including CDMA, WCDMA, EDGE, HSPA+ and EVDO.
