T-Mobile’s next move could be devastating for AT&T and Verizon

An unnamed source tells TmoNews that T-Mobile is planning an initiative that would pay off subscribers’ early termination fees if they switch from a rival carrier to T-Mobile. Specifically the source said that the company is planning “a project codenamed ‘Houdini’ which will give switchers up to $350 in credit when they switch to TMO” with a particular emphasis placed “on families switching up to 5 lines regardless of contract end dates.”

Ever since John Legere teased Uncarrier 4.0 on his twitter account earlier this week, I’ve been racking my brains trying to decide what it’s most likely to be. In terms of its own plans, value and available products, T-Mobile has done about as much as it can do to convince customers to join. It has unlimited (and unthrottled) data, international roaming, a non-contract plan, and the ability to upgrade whenever you want. So, what else could it possibly do?
