Ive been using this modem from long time and I hate using this modem and I purchased this modem for 1000rs in snapdeal I lost modems sim tray and replaced again it is not suitable for nano sims you need perfect full sim to use this modem otherwise your sim gets struck in modem and jio is not compatable it takes long time to get connected and although the speed is average and some gets low and high its better to buy other competative modems available in Flipkart and amazon finally I don’t recommend this to anyone
