I am a international traveler. I have bought a prepaid mobile connection of Air tel , the leading mobile communication provider in India., from Mumbai. The vendor told me that this particular plan will have Rs 450 talktime. However what he did not tell that out of 450 , Rs 200 talktime can be used only between the phones from the same company. As a traveler I am not going to find the phones of the same company I believe that this is not fair and I will not recommend this product to anybody, in fact not only this product, the entire AirTel products!
