So when BSNL sim is roaming in Delhi.. you are on Vi.... 2G, 3G or 4G?and the number is of Haryana so should I keep roaming on and select VI network or let it be automatic?
and is it automatic or you have to manually select Vi?
And though this does not seem possible but does VoWIFI work(since Vi VoWIFI works in Delhi)...
