Before signing into a contract with T-Mobile you may want to try and test out the public wireless your wife has available to her at work. UMA will not work on every single wireless network you find and if you are able to get UMA on your device the call quality may be horrible if the bandwidth available is low.
When I worked for T-Mobile there were always folks who neglected to do some research before signing on only to call later complaining they lived in an area with zero cell coverage (I never understood that one, they signed up with T-Mobile so how is it T-Mobile's fault they live in an area with no coverage... check the coverage map for where you plan on using the phone before signing the contract maybe?) or their 8320 wouldn't work on UMA with <insert name of some unknown 3rd party wireless router or public wireless network here>.
Take what the salesperson in the store with a grain of salt especially if you hear them say "Oh yeah, you'll get UMA anywhere you can get wireless."
