Whether you save or don't depends on a lot of factors and really it's an individual things. So no one can say it saves or doesn't save for anyone else but them. And I suspect a lot of people saying it doesn't save haven't even done the math and have just regurgitated what they were told.
for example we have 4 smartphones 700 minutes( use less than 200 ) unlimited texting and four 2GB data plans
Old pricing $240
New pricing with 8 GB shared $250.
Now it seems we'd pay $10 a month more BUT we uses less than 4 GB a month anyways. Last month used under 2 GB total in fact. If we switch to the 4 GB package we'd save $10 a month.
Now I think a lot of people are the same way but they have this mindset "Well I have 2 GB now so I need 2 GB on the Share Everything plan". Even though they don't ever come close to using 2 GB. It's almost as if having a plan that offers under 2 GB per person is wrong to them. 2 GB was just an arbitrary number to begin with.
Not confused, I did the math and it would cost me almost 25% more a month to switch from my unlimited plan with verizon to the share plan. Thats not to say it is more for everyone cause it isn't. My son will actually pay less than he pays now on his phone when he upgrades. Like you said, it all depends on what each person or family has now and which plan they intend to switch too and how many phones they have or are going to add. -- HughesNet elite plan/.74 dish w/1watt trans. / 9000 modem / 3 computers on a linksy's wired network
