NO, because a 32GB iPhone 6 does not exist in any country - it is only 16GB, 64GB and 128GB.

If you want 32GB, then you will have to buy an iPhone 5s.

No.

There is no 32gb iPhone 6 or iPhone 6+

FYI: Please remember FaceTime is banned in UAE, so if you desire that feature. You will need to look into other options. Cheers!

You are welcome.
