Good news for Pakistani mobile users Now they can topup their mobiles, both prepaid and postpaid, using pakcoin and get discount of up-to 25%. Top up can be had from topup.pakcoin.org. The process to get mobile topup through pakcoin is to buy Pakcoins from any of online exchanges (you will get more discount, if you buy through bids rather through tellers) or any Pakcoin teller (listed on Pakcoin.info/tellers).
