Reliance Jio 4g
Jio provide 4g Internet for free till 31st December with zero cost so I suggest that everyone take a sim. After 31dec. If its pack is not expected then u can stop using, after all u have nothing to pay. The sim is free calling, data, sms, video calling.every things r free. After too many users the speed of 4g is not 4g but its free.U SHOULD HAVE A JIO SIM.
