If 2G speeds were what they were when it was heavily used? Sure. Nowadays? Not in my experience. I got downgraded to Google Fi’s 2G in a well-traveled part of Virginia using a flagship Samsung and I couldn’t even load directions on Google Maps where I’d already downloaded most of the map for offline use. 2G ain’t like it used to be when it was still given a second thought by providers.
It’s not only the providers. 2G is 120kbit max on a lot of networks and 50kbit on average. Even a 1MB site, that is lean by today’s standards will take 160 seconds to load.
2G is really from a different age. Does anyone remember WAP and i-mode? I was certainly not able to afford data back then, but that is what all the business’y types were raving about.
