Shrug. 4G just happens to work for me I guess. There's nothing wrong with the technology, but a lot is wrong with some carriers.
I honestly don't understand how people put up with carriers like AT&T and Verizon, Sprint and T-Mobile. Their plans are (almost) 10 years behind in performance and 10 years ahead in price.
I have 50 down/10 up 4G from work and "unlimited Mbps"/50 Mbps private, practically it's about 100-150/50 Mbps. My phone is capable of 450 Mbps, that shouldn't be the limiting factor. Neither have caps nor throttling. Some months I use almost 100 GB. Ping to my home server is about 15-20 ms (fiber).
And I've been getting 40-50 Mbit on HSUPA, now in Europe getting 10 out of a "4G" connection is hard.
I don't know what bubble you live in tbh.
