Recently I buy the jio Sim card from nikol
speed is good enough to use online browsing, Mobile and Laptop both the devices can be connected, but download speed is slow .JIo network is bit slow as compare to all others 4G network service provider .But there is no download limit, everything is free of cost.but best thing is "Its free right now "! So best way, You use a separate phone for using Internet and your work phone must be different .I give 4/5.
