I have an iPhone 6 that is Sim locked by sprint, I need to switch the Sims carrier to T-Mobile.

Is there anyway I can go about this? Need information ASAP

I assume the only way to do that is either go to Sprint and get them to unlock it for a fee
or find one of these sites that claim to unlock your phone...for a fee.
