Yes, you can use it if it's unlocked. Usually, when you buy it from T-mobile, they'll give you the unlock code after couple of weeks. Since they don't have the Treo, then you would have to ask the carrier, which would be AT&T since they are the only other GSM carrier. You would also have to set up the settings to use T-mobiles internet.
As for the plans, the Unlimited internet plan with hotspots is $20 if you combine it with a voice plan. You can call customer service or do it via online.
