this is good initiative
i know so many people who take 10 iphones in 1 flight to sell it locally
Try to rethink it. This is different than importing a cellphone.
No foreign exchange leaves Pakistan when overseas pay for those phone from their overseas account. Quality product comes to Pakistan market to fullfill the local demand.
If in this process overseas Pakistanis make few thousands rupees than it's not a big deal.
When they visit they spend much more in local economy so benefit we get from their visit is much more than few thousands those hardworking OPs make on phone or perhaps they give them as gift to their family members.
