"Un-carrier is a movement, not a marketing strategy. We are freeing consumers from the predatory practices of traditional US wireless companies and that includes these plans that start with a low price and a low data limit, but then hit you with insane fees if you send one too many emails," said John Legere, president and CEO of T-Mobile. "It's wrong! And I personally want to drive those ridiculous schemes out of this industry. We will continue to be relentless and bring this forced march of change to the market every day so consumers can be creative with and enjoy the true benefits of wireless. I know we have it right and when we all are done reporting results from the first quarter - I think you'll share my conviction."
If you hit the 500MB, T-Mobile will prompt you to purchase a day or week pass or switch to a Simple Choice plan.
The company also noted that the Simple Starter plan does not have international texting and roaming. You'll need a Simple Choice plan for those features.
