Uber/Lyft, whatsapp, cashless payment apps all work reasonably on 2G and fine on 3G. Real time video calling works great for me over 4G/LTE, in the US, China, Argentina, everywhere I’ve tried it. I’m all for faster/better mobile Internet, but I keep seeing these claims that there’s going to be entirely new business models because of 5G and I just don’t get it. Better coverage for 4G/LTE seems like it would do a lot more good for businesses.
