Hi! I just preorder the IPhone 6s Plus And choose the t mobile contract free option And pay the full price. Do you know if this phone will come unlocked?? I want to use it in Peru. I already know the bands are compatible. My only concern is if i can switch the Tmobile sim card for the sim card i use ok Peru. I haved call Apple 1000 time but they gave me diferent information each time. Thank you in advance for your help!
