Once you do cancel your plan—they’re going to waive the early termination fee—you can get a reimbursement for any handsets, accessories and content you purchased through Disney Mobile. It looks like out of the MVNO operators, Helio is doing fantastically, with a $270 million cash injection, and everyone else is holding on to the railings.
