Care to fill us in with details to go along with your snark? Which part of 3rd world America did you visit? Anecdotally I enjoy decently fast broadband and mobile data coverage.
T-Mobile barely exists out of the city itself, and yeah, speeds are abysmal. $50 for a sim card too...
Anecdotally I went to the Swedish countryside in january; where I got 16Mb/s over 3g. (and it was free because: EU roaming is free on my carrier)
also free 4G with no data caps.. they might be slower than the others but they own their own cell towers and offer the best deals.
