After jio had launched his plans and tarrifs all the other operators are in problem as these days nobody use airtel, idea, aircel and vodafone. In these conditions all the operators are trying to launch new tarrifs and new plans. But although they are not getting success. As we know that jio have calling problems and BSNL have internet problems , so they have done a partnership with each other. And you will happy to know if you are a BSNL user that BSNL callings will be free from JANUARY 2016. And as they have a done a partnership with jio they will get good internet speed for all 2G and 3G users. So I would recommend you to go to stores and buy BSNL sim now as the conditions will be denser as jio had .
