Yeah, there's not much saving for me either. It'll cost $200 less over the course of two years if I go with 2 lines and T-Mobile's unlimited data plan (compared to the 2 lines and 6GB share everything plan I have from Verizon).

But, as you say, the Verizon plan lets tethering be as much as that xGB as you want. And for me, T-Mobile only offers very slow 2G service in my area while I get LTE from Verizon.

After those first two years, you do start to save real money ($40 every month, in my case), but that assumes you don't then upgrade to the latest iPhone or whatever and start all over again.
