Don't buy these expensive phones if you are living in Pakistan because of following two reasons ;
1. It will put your life in danger because of street crimes associated with Mobile Phones.
2. Pakistan doesn't make these phones/devices which means Pakistan has to import it resulting in demand of foreign exchange which put pressure on prices of other consumables and in turn depreciates our rupee.
At the end of the day choice is yours, I don't live in Pakistan that's why I do use these devices but if I was living in Pakistan I would never buy such a thing.
