ATT has a few phones (the new Blackjack II and the Tytn II a/k/a "the Tilt") which handle the US 3g standards and 2100mhz. The Nokia E61, E61i, and E65 all have 2100mhz. The Nokia n95 can either have 1900mhz or 2100mhz so be careful.
You should also be aware that ATT and TMobile will be using incompatible 3g standards. ATT will be on 1900/850mhz. TMobile will be on 1700mhz. In sum, there will be four frequencies for WCDMA worldwide. 3 for the US. 1 for the rest of the world.
I like the E series Nokias because they have built-in VOIP.

Stu -
So, are you saying that phones like the e61 series, e65 and 2100 ver. of the e95 can be uses in both Japan and S. Korea? What is the diff. in systems between S. Korea and Japan? From what you say, can I stick a T-M SIM (or ATT or MaxRoam) SIM in one of these phones and roam there? They all claim to have roaming agreements there.

Make use of T-M's UMA/wifi free calling from any place in the world with access to wifi. I use an LG G6, wife an S7)
A/o Oct 20, 2013 no need for intl prepaid as T-Mobile U.S. includes voice roaming at 20¢/min (in and out)., unlimited text (in and out), and unlimited data in 140+ countries.
My Plan -[6 lines] U.S. T-Mobile unlimited minutes (incoming and outgoing), unlimited text, fast data on each line. that $145/mo. total! . (In U.S. no surcharge for calling a cell.) If a line exceeds 2G of data in a month, pay $10 more for that line. [That only happens a couple times/year.
