Nice to finally have something go my way with the old Sprint phones! My wife's old phone is an iPhone 5 locked to Sprint. It was original, meaning it's never been in to Apple for service until today. Her battery has been swelling and so I finally made a move to have it swapped. $86 and change because they only charge you for the battery out of warranty. Here's the good part. I wanted to keep the Sprint SIM since those are tied to the phone. The genius asked if I had a backup, blah, blah blah. Answer was all no because this phone hasn't been used as a primary phone since February 2015 and my wife doesn't use it and I don't. So, pretty stock phone. I told the genius we weren't even with Sprint any more. So, during setup she asked me to choose a carrier - either Sprint or Verizon. I don't look a gift horse in the mouth. I chose Verizon - because all Verizon LTE phones are unlocked. And you know what? It took my SIM! When I got home I tried my tablet SIM and I had data on 4G. I tried my 6s+ SIM and my son called me and the phone rang. So…yeah. I now have a formerly Sprint iPhone 5 unlocked! It's 4G but it works on T-Mob's network! Pretty happy about that!
