AT&T (previously Cingular)

AT&T uses both 800 and 1900 MHz frequency bands for their GSM network data and voice services. Therefore, it is important to ascertain which frequency AT&T is putting into use in your area.

Our Advice

AT&T's complex network infrastructure utilizes both 800 and 1900 MHz frequencies. Therefore, the most simple solution is to opt for a dual band cellular repeater, which will always work with the AT&T Network. Try the following dual band repeaters:

However, in most cases we have found that AT&T uses the 800 MHz band for voice services, so you can be reasonably assured that 800 MHz repeater will in fact work despite the AT&T Network complexities. If you wish to try this, bear in mind that we offer a money-back guarantee on our repeater kits, 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.

Other Options

Another option to consider is using the Wireless Advisor website and entering your zip code. This is usually a good source of information, but when it comes to the AT&T network it usually informs you that AT&T holds a license to both 800 and 1900 MHz frequency bands - not which band is actually in use.

Alternatively, you can contact AT&T and ask for information concerning the frequency band in use in your area. This can be a reliable source of information if you can get in contact with a knowledgeable AT&T representative.
