Looking at the specs for the recently-announced T-Mobile REVVL, it looks like the phone lacks any 3G/4G support on non-North-American bands. Most notably lacking band-1 UMTS. This would mean that this phone simply will not work in Japan, S. Korea and Singapore; and would provide a poor experience in most other countries where 2G is being depreciated as rapidly as it is here. One would think that T-Mobile learned their lesson with the Leon and Galaxy Prime. Someone please tell me I'm wrong and the specs just failed to include those bands.
