I cut our high speed cable a few months ago and it had nothing to do with being cheap. The devices to get connected to the four networks were not free nor are the monthly fees. Combined it's more data than we can use even trying since one device is unlimited and another has binge on. They won't stream HD but if we just had to have that we have 33 gigs of LTE data that will.
So had I not cut off the high speed either it or the devices would have been sitting idle here at home. No reason to pay double.
