T-Mobile just updated its prepaid data plans a month ago, and now it's the corporate crowd's turn for a shakeup. The new (and quite frankly daunting) array of primarily business-minded plans is based around whether or not you'd rather face throttling or overage fees if you push past a set cap. Overage Free plans for subsidized (Classic) and unsubsidized (Value) devices are largely self-explanatory and slow down that bandwidth cap-busting hotspot, modem or tablet until the next month. The High-speed plan range costs lower as a matter of course, but you'll be dinged to the order of two to 10 cents for every megabyte over the limit. That said, there's some bargains to be had versus other carriers, especially with the 5GB and 10GB plans. Provided you're happy with T-Mobile's coverage, it may be worth signing up to eke out a few extra dollars in savings every month.
