I'm only getting 10-15 mbps in Sacramento, Ca on my 5s via AT&T. Coming from a 4s w/ no LTE this is a big improvement, but not really all that impresses. Thankfully I get 50+ mbps on WiFi @ home. Hopefully LTE-A will be much faster.
Fastest I've seen on Verizon. I live in Houston.
What can't you do with 10-15mbps down?
Dallas, TX again fastest I've ever seen!
