Reliance JioFi is a Compact and high performance 4G Router with use of Jio sim you can enable hostpot and can connect 10 devices easily. its upto 31 June 2017 reliance is giving 4g net with 4 gb high speed now it is 1 gb. but suppose if you have 4 jio sim which freely available then you again get that high speed net with this device. I m loving this device. This can connect minimum 25 devices without any issue in connectivity.It delivers upto 40 Mbps speed. The speed depends on area network. I am sure you will get best speed where ever you are. Thank you
