In a time where carriers want nothing more than to charge you an arm and a leg to use their ultra fast data networks, struggling T-Mobile is willing to go the other route and offer you unlimited data for cheap. Announced tonight, T-Mobile is launching a truly unlimited data plan on September 5. This data plan features no data caps, no speed limits or bill shock, and offers the “ultimate worry-free experience.”

This new unlimited data plan will cost $20 per month when added to a Value plan, and $30 when added to a Classic voice and text plan. For example, a single line Value plan with unlimited talk and text and unlimited data would cost you $69.99. A Classic voice and text plan with unlimited talk and text, paired with an unlimited data plan would run you $89.99.

T-Mobile may not have a 4G LTE network, but they do have a solid HSPA+ network that is capable of some impressive speeds, while not destroying batteries in minutes.

Talk about an option. 

We aren’t sure if this is the case for every Verizon customer, but so far this week, we have heard from a handful who used an upgrade over the past few days and were still allowed to keep unlimited data. From what we were told when Share Everything plans went live, unlimited data was only going to be kept if you purchased phones at full retail. We aren’t sure if Verizon is being extra kind this month, if they are temporarily allowing upgrades as they did pre-Share Everything, or if this is some sort of an error in their system. AT&T announced their shared data plans this week and even announced that customers will be able to keep their existing unlimited plans with upgrades for the foreseeable future. Maybe Verizon wants to align themselves with that?
