I use AT&T. My monthly cap is 45GB. ‘Course, my monthly phone bill is $275.
AT&T Caps to help lessen strain on their nearly saturated grid. Upgrades in AT&T take years sometimes a decade or more. AT&T since the split has only done minimal upgrades. They are too busy rebuilding what Judge Greene destroyed. Remember years ago Fiber Optics was going to fix it all? Well it only happened in very limited venues. DSL unless on fiber optics is a within three miles from the central office service. Cable feeds through AT&T as does cell phone carriers. MS needs to back off and let technology catch up. So does a lot of IT departments. They make their websites inaccessible to a lot of consumers simply by the massive bandwidth it takes to access the sites. Yes a lot of people have high speed service but a lot are on usage Caps also and a lot lower ones at that.
