Where I live even 4G isn't all that reliable. Making a phone call is mostly impossible and a text message is hit or miss unless I'm in a town or along a major road, This is due to terrain and the general lack of towers. 4G is spotty at best and with many areas having no service at all. And I ain't never going to live long enough to ever see 5G out here.
But, I would agree that while 32KB is pretty minor for an internet connection, things have a way of stacking. 32KB here, another extra 32KB there and pretty soon things can get 'heavy' to use.
