Airtel Calling Cards in US and UK

Hello All!!! You must have heard about the airtel call home, and I bet most of you are enjoying its special offer services. Well for all those who have not switched on to Airtel Call Home will really regret for not availing low cost calling benefits. And you know the cost of living is so high and with a huge sum spent on phone calls, I was just running out of money.
I am pursuing my post graduation here in USA and my brother is doing his BBA from UK. We are the only siblings and both of us often need to talk for hours with our parents and grandpa as they miss us a lot and we miss them too. I am already enjoying Airtel call home services here and I am greatly satisfied with the uninterrupted network, low cost advantage, easy recharging, pinless dialing, quick dialing and more. At only 6 cents per minute and availing discounts every now and then including free talktime by referring friends, I just feel at home here.
Now my brother in the UK is also enjoying the Airtel calling cards benefits. Airtel is doing a great job launching this cheap calling card India in the UK. You cant' believe the call rates are so low! It is only 3.5 pence per minute through toll access and 4.5 pence per minute through toll free access and the Airtel is offering 25 minutes of free talk time trial to all subscribers there in the UK. My brother is also enjoying 50 per cent extra talk time over and above what he has purchased making it to only 2.3 pence per minute. He even got 100 minutes of free talk-time by referring to a friend. Now he is over the phone as per his wish any time!
