I currently have airtel connection and it is really giving me a worst experience. I am unable to connect to the customer for any of my concerns. So i have decided to port my number to some other provider. I live in bangalore. So i want to know which provider has the good network, voice clarity, faster connectivity, cheap call rates and some moderately fast internet???? I have the following options - idea, vodafone, tata docomo, reliance.. Which is good for me?
