So almost nobody in the US or Canada then... I get 800/20 for ~140/month, including the $30/month fee for "unlimited" data. My other choices are starlink or DSL which are a fraction of the bandwith or speed.
I self-host everything that's "home-only" at home but use syncthing, rsync and a few other thing to replicate important data to a mix of S3, backblaze, google drive and some PVs attached to a hosted k8s cluster.
It works well enough.
