How to get UMA working on a 9800 On T-Mobile

Capture on 10-06-2010 19-20-54 I recently got my 9800 and decided to use some instructions found online to enable UMA on it. A fair WARNING if you decide to do this you can seriously mess up your device if you do not follow step by step instructions or decide to mess with other options. The process does take some time specially if you do not have the necessary tools installed on your computer so make sure you have some time set aside before you decide to do this. Make sure to read the full instructions before you start the process. This is only for those that have a 9800 on T-mobile UMA does not work with AT&T.

The full instructions are found in the forums section of Berryreview, as well as credit to where the original instructions came from.

  1. I could imagine using the Rogers certificate that was used for the 9700 before the latest beta builds fixed the UMA might work on this also. Its the same step, just diff certificate. However it’s still a royal pain when you know the device can support it 😐

  2. I thought TMO and ATT had different radio frequencies for 3G – is this incorrect?

  3. Yes the 3G is not compatible but you can still use it on EDGE and UMA is just as good as 3G but requires WI-FI

  4. Too bad – I’ll have to wait for a TMO Torch – any predictions on that date?

  5. Luis thank you!!! for this article! While I don’t have a 9800 (yet) T-Mo’s UMA feature is always worth talking about. One of the most under-appreciated wireless technologies on the market.

  6. I’ve heard conflicting rummors that T-mobile was in talks with RIM for a touch screen BlackBerry and just recently I heard that they may not carry the Torch so there’s no telling what they will do, am sure will see something in the next few months besides the 9780 upgrade.

  7. Yeah is one of the main reasons I love my BlackBerry on Tmobile. Great use you can use it anywhere

  8. PS3 bietet interaktives Entertainment der n?chsten Generation. Profitiere von Blu-ray Disc-Filmen, Spielen in hochmoderner High Definition-Aufl?sung, einfachem Speichern von Musik, Videos und Fotos sowie kostenlosem Zugriff auf PlayStation Network und vielem mehr.
