I have had my 8320 for over 2 years and have been quite happy with it (only complaint is dust under the screen), although I really only use it for voice and no data. I am going to be transferring to Italy in the spring with the Navy and was wondering if UMA would still function if I switch carriers and sim cards? Or is UMA somehow tied in to the carrier and I won't have the option?

Cell phones are quite a bit more expensive over in Europe so I think I'd like to just keep this one if possible, and UMA calling is such a great option because cell phone plans out there are very expensive as well.

Thanks!

UMA is carrier dependent. Not all carriers support it.

Also the UMA certificates and settings or whatever on the phone are carrier dependent. So even if you found a local carrier with UMA, it very likely would not work with their equipment.

I would guess you'd be able to find a local provider with good enough coverage that UMA is less important. Of course you'll face more roaming issues if you're out of their local area.
