Lots n lots of straws sucking from the fountain where I live. LTE is slower than dial up during peaks.
So I keep my phone set on 3G mostly as it's not only faster but I get better battery life by turning off the radio that's frequently hunting for better, then ends up switching back to 3G anyway.
Why run a radio that my phone prompts to first and results in really, really slow downloads?
Now when I'm at some places in the big city the LTE is marvelous. Faster than the data my work computer that's plugged in to the 'blue cord'...
