anyone explain to me in detail what is UMA and how it can be used please.

do you need a data plan to use it?

Thanks

UMA is voice dialing over IP. It uses your WiFi connection to deliver the call to T-Mobile where they add it to the terrestrial system.

Do you need a data plan - NO. Both of my kids have T-Mobile BlackBerrys without data plans, and they can use UMA. They have no other data plans.

Unless you get a special plan from T-Mobile, please note that these calls still count against your minutes. The key advantage is voice / text (for them) in areas with weak coverage, but with WiFi (like our basement).

I hope that this answer is detailed enough.

Yes, I used to have a 8820 and seen the "uma" on the screen a couple of times but didnt know how to use it. Ordered a Bold now, so how does it work through that?

The Bold doesn't support UMA.

The T-Mobile Bold, as in the Bold 9700, does.

I stand corrected. And that is good to hear.

I believe all T-Mobile devices with WiFi are UMA capable.
At least all the ones I've tried are.

ifonline · 11-28-2009, 10:41 AM

That seems to be the case based on browsing through the T-Mobile website.

Xion901 · 11-28-2009, 11:15 AM

What if it was on AT&T but unlocked and now through t-mobile haha?

ifonline · 11-28-2009, 11:22 AM

I assume it would work, right? No idea, though. I am on AT&T (and have been for many years), and so I don't have any experience with either UMA or T-Mobile.

NJBlackBerry · 11-28-2009, 11:27 AM

NO! It will not work.
It MUST BE a T-Mobile device.

People have tried unlocking Bold 9000 BlackBerry (they have WiFi) but UMA does not work.

An AT&T 9700 will not pick up UMA on T-Mobile.

ifonline · 11-28-2009, 11:31 AM

Ah. I didn't know that. Thanks for the clarification.

Xion901 · 11-28-2009, 09:57 PM

thanks, ifonline hows the 9700?

ifonline · 11-29-2009, 07:58 AM

It's the best BlackBerry I have owned to date. I was happy with the Bold 9000, but I always liked the form-factor of the 8900 better. The 9700 puts the best of both together, if you ask me.

Xion901 · 11-29-2009, 10:54 PM

Nice nice lol maybe for the future, by the time i decide they'll prob be a new one out haha, theres news phones out every time.
