I have been using this mobile service for the past 1 month in Bangalore. The service is very good. The voice reception is extremely good except for occasional feeble voice/disturbance.
The service was provided within short time, within 4 days, even though they promised me to provide connection within 2 days. The staff are courteous. However, the technical/commercial information available with them looks just sufficient. They cannot handle real technical questions about the network. However, I could get the reply through e-mail within 2 days, as my mail was forwarded to the concerned person.
The staff could immediately give me a demo of the functioning of the phone. As one of the reviewer pointed out the warranty on the instrument is not there, but I was given an option of purchasing the instrument from the market. I was also given the details that I should look for in the hand set, to ensure its compatibility. Finally, I decided to take the Kyocera hand set itself, rather than venturing into the market.
