Verizon- For your basic voice coverage, an 800 Mhz repeater (or dual band repeater) is most likely the best option for you.  If you are based  in Texas or Florida, a 1900 Mhz repeater (or a dual band repeater) is probably the most suitable option . Verizon makes use of both the 800 and 1900 Mhz frequency band in their cellular network. You may like to try it , knowing that our repeater kits come with a 30 money back guarantee, in case you select a repeater that supports the wrong frequency. Verizon generally uses 800 Mhz band for voice services so that 800 Mhz repeater will work despite the Verizon Network difficulties, except for Texas and Florida as preivously mentionned. In those two states, Verizon usually utilizes the 1900 Mhz frequency band.

Sprint- uses CDMA technology with a 1900 MHz frequency. In general, 1900 MHz (or dual band) repeaters can be used with the Sprint PCS network to improve cellular reception and coverage. The Sprint PCS network has also made some national and regional CDMA roaming partnerships in order to increase their coverage area. If your phone is in a roaming area, then it is subject to the specifications of a different cellular network and because of that it may be using an 800 MHz signal. If this occurs, your phone should be displaying a roaming icon.

AT&T- uses both 800 and 1900 MHz frequency bands for their GSM network data and voice services. Therefore, it is important to determine which frequency AT&T is putting into use in your area. When using the AT&T network, the most simple solution is to opt for a dual band cellular repeater, which will always work with the AT&T Network. However, in most cases AT&T uses the 800 MHz band for voice services, so you can be reasonably assured that 800 MHz repeater will work even with AT&T Network complexities. If you wish to try this, keep in mind that our repeater kits come with a 30 money back guarantee, so if the 800 Mhz product fails to work you can try the 1900 MHz model or simply have your money returned to you. Exceptions to this are North Carolina and South Carolina which use 1900 MHz cellular signals. Furthermore, AT&T generally uses the 1900 MHz frequency band for its HSDPA/UMTS broadband data service (for both cell phones and broadband data cards) so a 1900 MHz will generally be sufficient for this service.

The Metro PCS- uses the 1900 Mhz frequency band everywhere, so all 1900 Mhz single band repeaters that we sell are suitable for use with this network. These 1900 Mhz cellular repeaters will improve both voice and data coverage for the Metro PCS network.

Alltel utilizes both 800 and 1900 Mhz signals within its cellular network. In many states, Alltel uses 800 Mhz frequency signals only, therefore selecting an 800 Mhz repeater will always work for these areas (this applies to voice coverage – broadband data might be different). These states are as follows : Nebraska, Wyoming Arkansas, New Mexico Minnesota, Texas Kansas, Oklahoma, North Dakota, Utah Colorado, Nevada. In other states, Alltel utilizes both 800 and 1900 Mhz frequency bands in different areas.

T-mobile utilizes the 1900 Mhz frequency band for their entire network for its standard network (voice calls, text messages, EDGE data). 1900 Mhz repeaters will therefore boost any T-mobile signal for use with mobile phones. For its 3G high speed data network, T-mobile utilizes the 1700 Mhz frequency band. There are currently no 1700MHz amplifiers available from any manufacturer. If you need to improve your T-moblie data connection, you can connect your phone/data card to an external antenna.

Cricket

Cricket make use of CDMA technology of 1900 MHz frequency in all the areas they operate. Any of the 1900 MHz frequency cellular repeaters we sell will amplify mobile phone signals from the Cricket network, and will improve both cell phone signal and the wireless cellular data cards service.

Nextel makes use of iDEN technology that works on different frequencies that are unique to their network. Nextel requires a specialised iDEN compatible repeater to improve the cellular reception.a

Other Network : Your network provider can be a valuable source of information on which frequency they operate in your area. We would advise to ask to speak to a technical support as the quality of advice can vary considerably from one carrier to another. In general, reliable advice can be acquired from a network provider.
