Welcome to the Internet Age
I think this brings phones to the Internet Age. While the wired Internet has felt like a global network for a very long time, the phone networks have lagged.+T-Mobile
just changed the game, cutting the price of high-speed roaming data by 99+%, and adding unlimited 128kbps roaming data. They also took care of making international voice and messaging cheaper (free in many cases, 20 cents a minute otherwise).
And obviously, this being T-Mobile, all of that is available without a 2-year contract and without making me pay for a subsidized phone.
Everyone else, your move.
