It is. You typically either have only cellular connectivity or you have fiber, with very little in-between. And fiber provides 1/10G capability.
Is it _used_ universally? No. But the capability is there.

This is not going to be a cheap device _anyway_.
Working in this field - yeah don't underestimate what's available in "poor" countries. Most do better than poorly governed "rich" countries. And don't use it as an excuse to aim lower. CPE class devices do have a pretty long lifetime.
