So I have been researching and trying to sort out the info and whenever I feel like I have found what I am looking for it always seems that their is something to contradict it. I signed up for the Apple Upgrade Program for the iPhone 7S+. I am currently a Sprint customer but I chose the 24 month agreement with the Apple Store; I was under the impression that I would be able to move my service to another provider due to not being locked into a carrier agreement. Is this correct? Will the Sprint model allow me to do that? It says under the plan that the phone is unlocked but what I've searched through on here says choosing Sprint when filling out the details will/might lock you to them; is this true? I need to know because I want to ditch them for AT&T or T-Mobile asap. Thanks; I also apologize as I know most will say "use the search." I did but all this info is conflicting and I need help ASAP.
