Just a faster way to gobble up data
The Verizon network is truly superior to other networks overall, but AT&T and Verizon are both behind with the times. While the 2 inferior networks are making upgrades and offering better plans the big two are not offering more of an incentive. Just because a phone can download at 150 mbps, it doesn't mean much to most people. I feel once you get to 10mbps and have a low latency, most people will be content. Sprint and Tmobile may be behind in network coverage, but they are investing and creeping up slowly to the big 2 while gaining subscribers.
Unfortunately the only reason the other 2 make those offers is because they can't come close to competing on coverage.
But this is also something other providers, at least T-Mobile, have been doing for at least a year. Just like "XLTE" is simply the same LTE that T-Mobile uses. When did Sprint Spark come out?
But it's like Apple. When they do it, it's thought of...
You say "inferior" as if it is fact rather than your personal opinion...
