Very convenient

I frequently call Pakistan mobile to mobile. It is brilliant, no other service lets me call Pakistani mobiles for so cheap and from my own mobile!!

I really love the billing process, it updates your balance within seconds literally. It is really quick, efficient and easy to use. No cards, no hassle.

I only have one complaint. I don't know if this because of my phone's provider or my friend's provider but unfortunately sometimes the call quality can be quite low. However overall, I can say the service is great.
