International data pass caution

T mobile is usually up front with their billing, which I love. Like having fees and taxes included in their monthly bill - no surprises. I have run into trouble with their International data pass. They advertise 15 gigabits of international data to use in 30 days for $50 USD. That is not what you get. In the small words of the contract it is 15 gigabits of data AFTER you use all other data. So if you use a large amount of your PAID data toward the beginning of a billing cycle you could use all of your free 5 gigabits of free data then run out of time (30 days) and end up with no high speed data. 

T mobile should be more honest in their advertising and let you use your paid data as you want and free data when you run out. I see no advantage to the customer in this case, just a win for T mobile.
