I don't know why anyone would use EasyPaisa, Upaisa etc over Visa / Mastercard. It's nothing but a headache.
As per SBP policy, Visa / MC transactions are absolutely 100% free nationwide with ZERO tax. Same goes to ATM cash withdrawal and P.O.S (Point Of Sale) purchases.
As an added bonus; you can also purchase Android/Apple apps & Windows 10 softwares, pay utility bills, top-up your prepaid SIM connections and import stuff from AliExpress, ebay etc.
I wonder why people instead elect to stay in the late 90s by relying on these globally obsolete cellular payment methods?
