how can u say calling cards are cheaper.they r really expensive for pakistan.o2 boltone would have been a great option but.........
I think he is actually trying to say that this bolt on is cheaper than prepaid calling cards (not the other way around). i.e. 3000min for £10 is cheaper than most(all?) telephone cards available. It does actually work out as amazingly good value for prepaid users, as if you are using a calling card from a prepaid mobile, you still have to think about the cost of calling the access number. With this, it's all thrown in!
