This isn't a change, it is T-Mobile fixing their glitch...
The plan was never called "unlimited international data", it was called "BlackBerry Unlimited International E-mail".
For years email and Internet data were billed the same - I guess they finally found a way to extract the right information to bill people.
Thanks for the warning though, I'm sure a lot of us relied on that plan for free international access to any data...
And why move away from them because of this? Good luck finding a similar plan elsewhere
AT&T is $24.95 for 20MB...
