I bought a mobile connection from Airtel Kerala (India) in the month of April. I specifically asked for international roaming. After waiting for 2 days it was confirmed that i can get the same with some additional fees. I paid the fees and a sim card was provided to me which they confirmed had access to international roaming.

When I went abroad to Moscow(Russia), i was not able to access any of the mobile networks. I complained through e-mail and with much delayed response, nothing much was done. I reverted back to the agency from where the sim card was bought just to learn that there is a defect in the sim card. In my next visit to India in June, they gave me another sim card, assuring that i can access international roaming.
But unfortunately, I could not access the network in Dubai(uae) and also in Moscow(Russia). After further complaints through email and usual delayed response, only reply i could get was to switch off and switch on the mobile again.

Being a telecom engineer I know the tits and bits of how mobile works. However the problem is not with the handset or the way i access the network.

Anyway, its around 5 months now and Ii am paying monthly rent for no use and its a heavy loss to my business.

At the end, I am fedup and dont know what to do. Moreover there is no response from AirTel.
