Hi Everyone, I haven't posted on here before but am looking to for some assistance. I'm going to be gifting an iPhone 6 + to a friend of mine who lives most of the year in Myanmar. He also travels a fair amount to other parts of Asia, but on occasion comes to the USA/France/Germany. I want to pay full price for an iPhone 6 + from an Apple Store (or purchase online). I've been told the Sprint version of the phone would likely be best for him since he primarily resides in Asia, and would that model phone would be most compatible w/ the variety of cellular bands out there. However, I've also heard the Sprint is notorious for keeping their phones "locked" domestically, and I'm also unclear on their international locking policy. I intend to take the phone directly to him, and do not want to to interface with any US cellular companies if possible w/ the aim of him being able to just pop in his Myanmar SIM and be good to go. Any guidance would be much appreciated!
