I bought JIoFi device as I had only 3g phones which was not compatible with JIO SIM and I was desperate to use 4G technology. I paid 2000 Rupees for the JIoFi device.I bought it from the Reliance Digital, store they were not able to provide me a Jio SIm stating server issue for almost 20 days.Somehow, I got a JIo SIM for myself& now I’m enjoying 4G speed internet, getting speed of almost 7MBPS. Connection Reliability& technical support is not that great to boast about. I would recommend everyone to buy this product for sure.
