iPhone 6s Plus with T-Mobile contact

[Android Central Question]

I have a iPhone 6s Plus Can I buy a straight talk chip and plan and use it on my T-Mobile contract carrier without getting it unlocked

 

[RumoredNow]

Probably not. Check with T-Mo about getting it unlocked.

For better information ask these iPhone loving folks. https://forums.imore.com/ask-question/

Straight Talk uses all 4 carriers, so make sure you get a TMobile SIM. Whether it's TMobile or Straight Talk TMobile, it should work. (But I'd get it unlocked from TMobile anyway, in case you want to sell it and someone can use it on a different carrier. Once you go to ST, TMobile won't unlock it.)
