[Resolved]  Idea Cellular — not getting any incoming calls

Please provide as much information as possible... Sir, I am using idea kerala sim, but when i came to karnataka, recharged a roaming offer also, it not getging any incoming calls. When calls to this no, it saying no. Not valid, contacted cost. Care, i change roaming setting also not getting calls. Sometimes call from karnataka comes. Much problem for kerala calls. I was using the same sim for about 5 years. Never faced this kind of problem. So going decide to remove the sim and connection permanently.
