Reliance jio, oh yes they extended till 31st march. I got my sim in bihar and it cost me rs100. Yes guys there are some dalas who are taking money be aware of them. Okay coming to the sim they provide a good service of internet which speeds up to 5.1mb/ps down speed but in only some particular area. I live in delhi so my sim is in roaming but it never lagged but going to some area like south ex, rajiv chowk, saket this sim speed slows down. Okay coming to the calling service I will give 1star for that and that is also becaise sometimes call are serviceable other vise whenever I call the network of every single people are busy. So guys if you want jio for calling sont take it and if you want it for internet take it as soon as possible. Now it is avaliable in all s shops
