Few month Ago. I was buying Jiofi m2s on My friend suggestion.he is telling me his advantages. Like it has micro USB port and Micro SD card Slot. It has powerfull lithium-ion Battery of 2300 mAh. Also provide maximum 32 devices connected. I was using this device last 3 month I was satisfied this speed is as well as improved and I was using jio sim through jiofi. In 3G smarthphone this will be a good option. Access jio sim in 3G device via Jiofi.
I will suggest u buy and try.??
