Re: T-Mobile Throttle Speeds: What Are They? What Is Edge?
IIRC "Edge" is a 2G data protocol. When T-Mob throttles a 4G-LTE account, they don't just throttle it down to 4G (HSPDA+) or 3G speeds, you throttle you down to their oldest slowest data network, "EDGE". They're not the only carrier doing this, IIRC Simple Mobile and Straight Talk do that as well. The good news is that EDGE equipment is scheduled for upgrade to 4G-LTE, so it will go away in the next couple of years. (AT&T says their EDGE networks will be shut down in 2016.)
And by 4G-LTE I mean the US "LTE-ish" speed, which is a fraction of what 4G-LTE is in other countries, but that's a whole other subject.
EDGE supposedly has speeds somewhere between about 9 and 60 kbps, depending on the implementation. Slow? With today's hopelessly bloated web pages, everything is slow.
