Earlier when I used to roam in Goa with my Vodafone Mumbai SIM card, I could roam on any network in Goa like Vodafone, Idea or Airtel.This weekend I was in Goa and I found out that I can only access Vodafone network there. All other networks like Airtel & Idea gave me "No access" message while manually trying to select those networks.My friend who was there last week also reported the same.Anyone aware about why this is so? Of course, its cheapest to roam in Vodafone network there if you are a Vodafone Mumbai user, but still trying to figure out whether there has been any change in policy.
