Since ESN swaps are not supposed to make any changes to the line of service itself, we were surprised to receive a letter in the mail from Sprint notifying us that our contract had been changed and that if we canceled the service before the contract ended, there would be an early termination fee (ETF) of $240. Interestingly, right under that, it said: “An early termination fee of up to $200 may apply to each line on the account if you cancel before your contract end date.”
Hmmm…that doesn’t sound right. Would the ETF be $200 or $240? Sprint's ETF policy has been to charge a maximum of $200 (and after four months, it begins being pro-rated based on how long you've had the service) - we have never heard of a $240 ETF.

If you see that letter like the one we received in your mail, don't be alarmed - but do pick up the phone and call Sprint at 1-888-211-4727 to confirm the terms of your agreement. The moral of the story is to always ask questions and make sure you are up to date on the terms of your agreement with your service provider - even SPRINT makes mistakes!
