Is my iPhone locked to Sprint, even if I bought it at the Apple Store?
I had an Iphone 5SE (not under contract), that I traded in for the Iphone XR with Apple's trade in program. I bought the phone at an Apple Store (I got $80 for the SE). I chose the 24 month payment plan. My carrier is Sprint. My question- is the Iphone XR that I got, locked in to Sprint? Or can I pop in another SIM card in there, if I travel to Europe and get a pre paid SIM card ?
Thank you.
iPhone XR, iOS 12
