A couple other carriers have already announced similar changes to their ETFs, but now T-Mobile has joined in. Today, the company announced that it is working on a more flexible Early Termination Fee system that will allow for reduced ETFs the longer a customer stays in contract. Instead of remaining static at $200 per line of service, ETFs will now decline as a customer runs down their T-Mobile service contract. Hot, right? Yeah, but we’re going to reserve final judgement until we see the concrete numbers. T-Mobile has only revealed that they are currently working on a new fee scheme, and should announce the finalized terms sometime during the first half of 2008. Of note: this will only apply to new customers and existing customers that choose to re-up their contracts. No retroactive clauses here, folks.
