Hello FriendsI am new to this forum so request valuable opinions from all of you; I will be travelling to Jamnagar for 3 months ; i have an existing MTNL 3g prepaid sim with Rs.2500/- unlimited plan in it; Just wanted to know if i can use it in Jamnagar with BSNL network. Are there any roaming charges that I will incur? Also I wanted to know if there would be any roaming charges if i make video call to MTNL mobile number in Mumbai. Will i also be charged if i receive video calls from mtnl local number while roaming in Gujarat?Thanks in advance for your replies.
