I use UMA 95% of the time. Home, work both have WiFi. Most other places I go and sit have WiFi. While UMA isn't always as stable during extended calls, it is more than acceptable IMHO. It supplements my carrier's network deficiencies and allows connectivity in buildings where tower signal cannot penetrate.

Iif you are moving simcards between phones, I am pretty sure you will need to request service books since RIM "knows" your phone, not your simcard.
Note that UMA requires a certificate on your phone. T-Mob sends it to you somehow. I believe when you wipe the phone and then load a fresh OS, the certificate is sent. UMA is a black hole of sorts. The carriers probably don't like it because it could be hacked. That is, you are getting into their network using the internet as a gateway. This is very different from Skype, which is strictly a data service.

UMA - which is NOT on the OS7 phones - is embedded (at least to some extent) in the hardware. Wifi calling was put in OS7 phones several months after they were released by an OS update. The 9810, being an OS7 phone, does not have UMA. (for some reason T-Mobile stopped selling it after a month on the market. I think att still sells it - but they never had UMA.).
On service books - It seems to me I have to do that with each upgrade (re-register)
On email over UMA - I never had a problem. Just turned off my cell tower connection - just leaving UMA, and sent two test emails (and received a couple) with no problem. I now am on OS6 w. a 9700. Always worked w. the first UMA capable phone onward (8320?)

UMA Rogers BB10 hopefull
Blackberry 9800 Torch with Rogers UMA works seamlessly for over 2 years now. It was a pain to get it working with many hours of frustration dealing with Rogers Tech support. I live in an area without cell coverage so the UMA is essential for me to stay connected. All features work the same as on the cellular network with Rogers. Hand off between cellular and WiFi is seemless. With a good router and high speed WiFi connection UMA offers the same conversation quality as cellular. Very few Rogers Customer Service people or their Technicians understand UMA .
I am very interested in the new BB 10 phones but will only switch if they support UMA... I'll be watching closely for reports on the new phones.
