As far as I am concerned it's just fine.
You won't get ~150 down, but it's consistent and coverage is good pretty much everywhere I go.
I average around 5-25 down, depending on where I'm at. I do have a 4G LTE Personal Cellspot though for home. Uses my home network for backhaul.
Compared to Sprint, from where we ported in late 2015, I can do anything I normally do and not have to worry about coverage or speed. It just happens.
We're on one of the older Simple Choice plans that were being offered in September 2015 though. We aren't on the One plan or any variation thereof. It doesn't matter as far as coverage and speed but it does where price is concerned.
West Valley, by the way. 83rd and Indian School for home, 59th and Palmaire (Glendale) for work.
