The most popular thing in india after demonatisation is jio* . We all know one can get a jio sim for free from jio store and company offers free voice calls, free 4g internet & free text messages for months. Co.’s stratergy is highly appriciable. If we talk about its networks thwy are not bad at all they give good speed all the time but not 4g at all as statef by compang. At night its speed increases and goes upto 5-6 mbps. And calling is not that good but its not at all bad deal if one get this for free. At last I sugest it to all using 4g phones. They can use it till 31st march.
