Jean, you're right and I was wrong. It's $130 for 30 gigs plus a device. So add a smartphone = $170 a month or just add a MIFI Jetpack and it's $150 a month. I added both for $190 a month.
I'm doing a blog post on this and I figured out how much it all worked out to price per gig this is it:
My old Verizon Plan: 10 gigs for $80 a month = $8 a gig
Price per gig when I went over my 10 gigs = $15 a gig
Millenicom: 20 gigs for $90 = $4.50 a gig.
Verizon More Everything with JetPack: 30 gigs for $150 = $5 a gig.
Verizon More Everything with Smartphone for $170 = $5.66 per gig plus unlimited talk and text
Add a line with a friend: 15 gigs for $80 = $5.33 a gig.
To compare how much you are paying per gig right now, divide the price per month by gigs.
If you have Smartalk or other unlimited plan you only get 3 gigs at full speed, the rest are so slow as to be unusable. I wouldn't count them.
Smattalk: 3 gigs for $45 = $15 per gig plus unlimited talk and text.
Smarttalk is by far your most expensive choice per gig! But if that's all you need, it's the cheapest per month.
