T-Mobile CEO John Legere has promised that a number of new Uncarrier initiatives will be revealed this week, and the first of those is a $40 Smart Starter plan. Set to launch on April 12th, Simple Starter bundles unlimited talk, unlimited text, and 500MB of wireless LTE data at a monthly rate thats $10 cheaper than T-Mobiles baseline Simple Choice plan. It also qualifies for T-Mobiles promotion where the carrier will cover your early termination fee from a rival provider so long as you trade in your current smartphone. And T-Mobile is quick to point out that customers wont be throttled or dealt unexpected overage charges in the event they exceed 500MB.
