Paradigm Shift for International Travelers
I travel about 10 times a year outside of the United States. For me this is going to be a game changer. Sure it's just a slow 128k connection but it's an always on anywhere in the world from wheels up to wheels down connection. No more stopping by vendpoint kiosk in Heathrow T5 or trying to find a sim card in some hofbahnhof exhausted after a flight only to be told it might take 3-12 hours for local sim to "activate" this is so much simpler! You ever tried to get a sim card in Italy? My passport has gotten more wear and tear in cell shops from Italy to Curacao then passing through customs.
If T-Mobile makes buying "travel packs" easy from their website I would have no problem shelling out the extra $$$ for 3g or 4g coverage while abroad without changing sim cards.
I'm with AT&T right now with an iPhone 5s... This just might be enough for me to bite the bullet and pay the ETF to get out of my still wet inked contract to switch to T-Mobile.
