Samsung Galaxy S6 International Version

Assalam alaikum. I am looking to buy an s6 or an s6 edge, all I want to know is if anyone of you out there have used the international warranty version (which is probably the international variant and not specifically for Pakistan), please tell me if there is any network related problem (like call drops, which are common in Samsung phones' international variant). Please answer only if you really have used that one. JAZAKALLAH

you want international remind me of something.
