Although the name for each network is different, these phones are largely the same (at least one marketing person at each cellular carrier is cringing as you read this). This allows me to write this book in a way that covers the common capabilities.
At a core level, these phones are built for high-speed wireless communications. The cellular carriers have spent kajillions upgrading their networks to offer more coverage and better data speeds than their competition. Again, this book doesn’t dwell on these differences in network technology because they don’t really make much difference (again, at least one engineering person at each cellular carrier is cringing as you read this).
I assume that you already have a phone, and I just hope that you have good coverage where you spend more of your time with your phone. If so, you will be fine. If not, you need to switch to another network because the experience with your phone will be frustrating. I would advise ...
