Friends, as we know we spend lot of time on internet studying, watching lectures like chokkhalingam videos, QIP, vision discussion and analysis videos etc which consumes huge data and speed is also not good. It is costly too when you are not in Delhi. Reliance Jio with cheapest data rate in the world can be ans to this. How can we get that sim in shortest time possible? Also which modem or 4g phone will be best to do teethring with PC?
Do the best you can until you know better. Then when you know better, do better.
