I am currently using TATA DOCOMO and the network here is very good. Only proble is that when i travel to Kerala, there is no network at all. Upon searching for networks, there is only Vodafone(but signal is too weak) and Cellone. I dont know what Cellone is. Is it Bsnl? So im planning on porting my number to MTNL because they have 3G in Mumbai which is cheap. But my question is, will i get network while I'm in kerala? Because I feel MTNL and Bsnl are the same. Correct me if i'm wrong
