$120 is the total (minus fees) that I see for two lines. I thought you were suggesting that you could have a whole family paying just $45 in total.

Setting aside unlimited plans for the moment: You can get 5 GB of data per month, which seems pretty generous to me, on an MVNO for only $15 per line.

Ah, sorry for the confusion there. I should've specified.

The family plans (whether on big carrier or MVNO) get cheaper per line while going up in total price. But yes, not everyone needs unlimited.
