I have TMobile and it was pretty good
I had service with Verizon
My T- Mobile worked pretty well. A little spotty for data in places, but I had 4G pretty much everywhere. My friend had Verizon and it worked fine. I also had a work phone on Tracfone CDMA, and it did great too! (CDMA=Verizon 3G)
i have t-mob and there was an area at the entrance but that was it.
Yes there are spots where you can get service through providers such as at&t and Verizon. I have Google fi and was able to get service in some areas.
