Again, this book doesn’t dwell on these differences in network technology because they don’t really make much difference in ways that you can see in a book. (Again, at least one engineering person at each cellular carrier is cringing as you read this.)

Similarly, most of the capabilities among the different Galaxy S20 models are similar. The S20+ has a bigger screen, a bigger battery, and ...
