T-mobile (unlocked) iPhone 5SE will not work internationally (japan & SE Asia)??
My current old t-mobile iPhone 5S* has worked fine (for me) in the USA and while traveling around the world (Hong Kong, Japan, etc) all without issue. I wish to buy to an iPhone 5SE but it appears model A1662 (the t-mobile model sold from apples retail USA website) will not work anywhere outside the USA!?!??!!
I’m in Japan currently and can buy the 5SE that’s sold here… the model number is different than the USA t-mobile iPhone SE sold from apples website, I believe the Japan SE model is A1723 (see here: http://www.apple.com/iphone/LTE/). I just don’t want to buy this Japanese iPhone 5SE, return home, and have a phone that won’t work on t-mobile, or worse; maybe not work at all anywhere (since i’m always using t-mobile sim card not domestic sim card from country’s I’m traveling, maybe somehow t-mobile sim won't recognize Japan 5SE phone?).
It’s imperative I’m able to travel with my “t-mobile-sim-card-using-phone“ and have it WORK most places (in SE asia specifically). My 5S does this fine, but apparently the SE is a downgrade in this regard. Do I not have a proper understanding of all this, am I missing something??
TL;DR …Which iPhone SE model will work both domestically on t-mobile in USA and also internationally (primarily SE asia).
