Idea Cellular — Network coverage issue

Address:

Bangalore, Karnataka

Name : Avinash Number : [protected] Many people are telling me that when they try calling me they are getting to hear "INVALID NUMBER" and the call is not connecting. I am in Bangalore (city) but still network is very bad in IIN. I have called customer care and complained still no solution. They are asking me to latch on AIRTEL if I want to use 3G network as they have tie-up. Getting stable Mobile network itself a big issue. I could not select AIRTEL network for this IDEA sim.
