UMA is calling on wifi connection but when u leave the uma wifi area the call does a soft HANDOFF to the network so u can keep talking.
Wifi calling same as uma calling but NO HANDOFF to network when u leave the wifi connection ur on the call will drop
UMA - unlicensed mobile access
uma and wifi calling same thing your making a call over a wifi connection.
Tmobiles uma work very good on 3G devices and that was mainly on blackberries ! then android came into the picture and they did not have uma built into the os of the android like blackberry did,so blackberry was not going to help andriod with uma, SO tmo got somebody else the get ( WIFI CALLING ) on driod devices thats when the name change from UMA to WIFI CALLING, tmobile didnt want to maintain 2 different ( calling over wifi ) so the 1st blackberry with the change was 9900 (4G) cause Rim still can put UMA in the os with a soft handoff but then. ALL tmobiles other phone would need it cause people would want the better of the two wifi calling feature UMA. hope this helps u understand the difference

Just got off the phone with Rogers. I tried to upgrade my UMA package on line but they have discontinued UMA for Blackberry phones and WiFi for all other phones. They wouldn't tell me why. But they did say that for those of you who currently have UMA/WiFi with Rogers, you can keep it and they will support it as long as you don't change your plan or phone. I did manage to upgrade mine to Canada wide for a small fee.

Great news. My contract ran out last December, but I decided to wait for this Z10 as it sounded brilliant, but then found out it didn't support UMA ( In which Orange now call UMA a different name, called 'Signal Boost') So I am sticky to my trusty 9700 until they sort this out, as I too live in an area with no network coverage, but have all the places I visit in the area wireless network key stored in my phone!
Hurry Orange and Blackberry..Sorry...RIM, as I'm guessing there are thousands of us wanting a new phone with UMA (Signal Boost) technology!

I have seen several people hint at the correct response but none do so clearly here.
Let me explain the difference:
1. UMA calling as the old Blackberries up until the 9780, 9800 and the 9360 was a hardware solution.
UMA hardware was built into the phone. It also allowed seamless handoffs from the wifi network to the cellular network. UMA is a feature that must be built into the phone itself.
2. Wifi calling which T-Mobile is now advertising is the same feature implemented in software rather than hardware.
This has been a trend in computing for years. Special features that initially require dedicated hardware later are implemented in software. I use a 9810 now and it has software based wifi calling, which works great minus the handoff that you would get with UMA.
So to recap, older UMA = Hardware solution. "Wifi calling" as they call it now is a software only implementation of the same feature.
Only phones with UMA hardware can ever have UMA calling, but ANY PHONE that is powerful enough can have wifi calling added through a simple software update as we saw with the last generation of BB7 phones.

It's not in the current T-Mobile firmware. I HATE it and shut it off on my Android phones, but I have a good signal here at the house. If I didn't, I'd want it.

I bought the Z10 last night, and I felt somethign fishy was going on when I could not find viber in the app store. Now I have just been told by TMObile CS persont that WIFI calling is a phone feature and the Z10 does not have it. Period. It NEVER WILL HAVE IT !!!!
I'm returning this phone and getting a Samsung S III - **bleep** it BB - I really REALLY wanted to help you
