issues soon then I think people will loose interest from their services, no matter even if it's free. I heard people saying about jio sim "pehle to milta nahi, milta hai to chalta nahi" translation "First It's hard to get a sim, and even if you get then it doesn't work"
They're even capping internet from what I've seen. Video sites like DM, vimeo and even Youtube now. Slow image loads. While having good speeds on speedtest.net
