Your T616 will work in the US with T-Mobile on their GSM1900 network. Or you can switch to Cingular, and the phone will work on their GSM850.

850mhz is really exclusive to Cingular, at least in the US at this time. Cingular is adding 850 gsm modules to all their towers nationwide, and will eventually terminate usage of its TDMA towers. MAny areas, including Kentucky, Indiana, and NJ have been converted. For Cingular, this allows us to offer the same equipment nationwide, as well as support the phones from market to market. Also, will allow Cingular to offer MMS, GPRS, and the other apps that are soley for gsm. Consider that most of the more advanced apps are being developed only for gsm, not tdma or cdma. |

AT&T has GSM800 (850MHz) as well. |

Really? I know they are converting all their towers to gsm 1900, but don't understand why they would do 850. I can see them (and T-Mobile) having phones that do 850, since Cingular is doing the conversions on our TDMA towers. |

wireless providers get licenses to use wireless bandwidth, and each license usually covers a few counties (or parishes in Louisiana)
US wireless provider broadcast at either 850 mHz or 1900 mHz.
for any given licensing area, there are 2 850 licenses (the old analog licenses) and 6 PCS licenses (for digital). there may be more PCS providers in a given area if the bandwidth is subdivided; however, there are no more than 2 analog, 850 providers in a given area
Until recetnly, GSM has been exclusively on 1900. Over the past six months, Cingular and ATT have been developing use of GSM 850 with Cingular leading the way.
The T616 supports GSm 850, which will allow it to be used in more places in the US than the T610. T-Mobile users will not notice any difference with the two phones becuase they are not affected by the use of GSM 850 at this point..although who knows what the distant future holds in store

Does anyone know if it is possible to change/upgrade the  T610 to an T616 so that it uses GSM 850 instead of GSM 900.
In other words, I bought the wrong phone for the US  The phone works fine, but reception is poor in places where it used to be okay with my T28 World).
Any help appreciated...

Does Tmobile use 850MHz any where in the US.Because if they do not use thatband why bother. |
