Jiofi is my wifi anywhere. Review on Reliance JioFi

I have taken JIOFI mifi device and jio sim to use internet anywhere. but initially I have a doubt about its performance. I purchased this device on a offer that which comes along with a JIO sim. but because of lack of stock I got only device but not sim along with it. After two days reliance digital people called me and told just come and collect ur sim but when I recached there those people told sims over. wait for next call, I got very much irritation and lost hope on sim and performance of the device even before I tested it. Again after two days I got a call and told you may get a sim tomorrow morning, Just ready to reach within 30 mins after U got a call from our people in next morning and this time I got a call and I went and collected sim. Sim verification is very simple and most secure.They Just asked for my aadhar and have taken my thumb impression using biometric scanner. After 30 mins SIM activated and inserted it on my JIOFI MIFI device and started to use wifi using it . initially it came around 2mbps after some time it started to come at a speed of 5mbps to 23mbps. This is 10th day with JIOFI experince its realy superb. THANKS TO RELIANCE JIO.
