Can i buy an iphone and i want to give it to someone outside my country and let him pick it up in there apple store is it possible?ipuine

I wouldn't recommend that way.

I suggest that you take into consideration the opportunity to give her an "Apple Gift Card".

So she can buy the appropriate iPhone 7 model on her country at her most convenient Apple Store (or Apple Store online), obtain the Apple warranty in her country, and use her new device wthout problems.

Read this support Guide:

Gift Cards - Business - Apple

This is my opinion.
