Question

what is the benefit of having maximum LTE band

Answer 1

Because the more band you use, the more people and data you can send and receive. And where 2600MHz for instance allow really fast performance, but low distance, for crowdy cities and stadiums and malls, 700MHz is the other way around perfect for islands, countrysides, etc.

Answer 2

Answer:

In terms of bringing your phone to a different carrier , the more band and frequencies your device has in common with that carrier , the better . It means your phone will be able to pick up either the carrier 3G or 4 G lte more readily , in more places .
