I have been a Vodafone user for the last 6 years . I am a frequent traveler and I travel to places where there is very limited Mobile connectivity. So where I go to I used to switch over to Airtel mostly or Idea from myVodafone since Vodafone doesn't have a good signal there.Since the last 1 year I have been unable to latch on to any other network apart from Vodafone in Kerala and Tamilnadu.

I have had long phone calls with the customer care and even the service manager .They finally came back to me saying Vodafone subscribers in Karnataka cannot latch on to any other network in Kerala except Vodafone of course!.
I want to check out if that is true.So,all my fellow vodafoners in Karnataka who have National Roaming activated ,could you please check if you are able to latch onto Airtel,Aircel,Idea etc while travelling to TN or Kerala.
Your inputs will be appreciated.
