T-Mobile has just announced revamped mobile broadband data plans that allow business users to choose whether or not they want to be subjected to data throttling when reaching their data cap. The carrier now offers both "overage-free" and "high-speed" data plans for use with its lineup of tablets, mobile hotspots, and USB sticks. If you pick overage-free, T-Mobile will throttle speeds when users exceed their data limit, just as it does today — but for those on the high-speed plans, T-Mobile will keep data flowing at its normal speed, though customers will be subject to the same types of overage fees they might get on AT&T or Verizon.

Regardless of which type of plan you choose, T-Mobile is offering data allotments of 500MB, 2GB, 5GB, or 10GB. Overage-free plans with throttled data have slightly higher base prices; 500MB of data will set you back $24.99 (without a contract and accompanying device subsidy) or $29.99 per month, all the way up to $72.99 (no-contract) to $77.99 (on a contract) per month for 10GB. If you're a business customer, plans start at $19.99 or $24.99 (on- and off-contract, respectively) for 500MB, with overage charges of 10 cents per MB — which works out to another $50 if you used twice as much data. Fortunately, overage charges drop significantly for the rest of the plans: the $29.99 / $34.99 2GB plan charges three cents per MB if you go over, while the 5GB and 10GB plans have overage charges of two cents per MB.

Unfortunately, T-Mobile is only offering these high-speed plans to business users — standard consumers will have to continue to put up with throttled data. For those who are eligible, T-Mobile says these plans will be available by the end of July — check out its press release to get all of the pricing details.
