T-Mobile Will Offer Unlimited Nationwide 4G Data Plans Starting September 5

Few smartphone users out there are happy with the way most carriers place limits on data plans. Many data plans out there offer you a specific allotment of data each month and if you go over that allotment, you either get charged more or your speed is throttled back. T-Mobile has made an announcement that mobile data users will really love; unlimited 4G data is coming.

T-Mobile has announced what it calls a truly unlimited nationwide 4G data plan. The plan will launch on September 5 and offers no data caps, no speed limits, and no unexpectedly high bills. The official name of the plan is the Unlimited Nationwide 4G Data plan. T-Mobile says it's the only carrier in the US to offer completely unlimited 4G data access.

T-Mobile customers on the company's Classic or Value plans will be able to upgrade their existing service to the Unlimited Nationwide 4G Data plan. You might be expecting the unlimited 4G plan to cost a lot of money, but it's surprisingly inexpensive. When added to a Value voice and text plan the unlimited 4G data will cost $20 monthly.

When added to a Classic voice and text plan, unlimited 4G data will cost an extra $30 per month. At that rate, a T-Mobile Classic plan with unlimited talk, unlimited text, and unlimited 4G data would cost $89.99 per month. I suspect this plan is T-Mobile's way of gearing up for the next-generation iPhone expected to launch next month. The next iPhone has been rumored to support 4G data.
