I am a person living in UAE. For my vacation i go to india. While in India I always use an airtel sim. The airtel works properly in India. So one day before departing to UAE i checked and there was Rs.100. But after coming to UAE some 10 days later when i wanted an number i saw that there was Rs 4.5 . I told my brother in India to ask the customer service to check about it. They told my brother that it is an rule to cut a certain amount everytime you are out of india. Now plz people never but airtel sims bcaz I dont want anyone of residing out of india to face this problem. read full review »
