I am using reliance jio sim from the last 2 months, Then when it came on the market this sim comes with it was only LYF mobiles. So I was not the first to use the SIM, but now every 4G smartphone users get this Sim. Millions of people are using it to sim, the first 3 months of unlimited data and voice calling sim free is why everyone is using this SIM. At the end of 3 months free unlimited data more people will not use it Sim, because the company does not give good offers. The network is the biggest problem of this Sim, The network is everywhere, but you can not use the sim Staying indoors, the sim is give best network in the city, but when you are inside the house when the network does not catch. This is the biggest problem of the Sim, I have to go on the roof to use the SIM, If the network will not be inside the house no advantage of using this SIM. The second problem is the data pack, The SIM is give 149 rupees internet for 28 days 300 mb data and give unlimited at night with this pack, I do not understand that only 300 mb for 28 days or every day will get 300 mb for 28 days, which gives unlimited Night data with this pack this is totally useless. When the SIM do not catch network in indoors is not used it will then go to the terrace at night ! , The company also is fooling us Unlimited Night Data pack, 1: 00 am to 6: 00 am can use unlimited night data. Now tell the person sleep at night 1: 00 pm or will use the net, this company should give, like every companys giving from 12: 00 am to 6: 00 am Night Data pack. First, you should make your network a bit strong and dilate, everything else will be seen later. That is why I am giving you 2 stars only. You should be make batter your network and offers, and explain more all of this company's packages.
