I am using BSNL 3G sim. It works perfectly wherever I am in Tamilnadu 3G sometimes and Edge mostly. Works perfectly on 3G in Chennai.
I have traveled to Mumbai twice and I am on Mumbai - Goa highway today. Connected to Dolphin and Cellone respectively. Though I can see the full strength signal bars, I am unable to access internet - error message says your connection not activated. Has someone found a workaround for this?
I tried the same sim on my 2g phone, I am able to make voice calls!!!
Hope someone can tell me what to do!
Anyone else with seamless roaming in India may post their experience so that it can be useful for others.
Thanks in advance
PS: Neither 3G nor Edge indications were visible while roaming in Mumbai / Maharashtra
