It's been cheaper, but right now it's a good spot between Mint's $15 3GB and $20 8 GB plan and cheaper than either at $13/month for 5GB (at the 12 month bulk price of $149.99).
Personally I'll be going with Visible's $25 unlimited everything party pay plan (since I'm dropping my ISP and need the unlimited hotspot). Venn also has a good deal right now at $20 unlimited everything+50GB hotspot.
I would have taken this FreedomPop deal though if I was still paying my ISP because I use about 5GB/month on my phone and it seems to be the cheapest for that amount.
Not the best deal around, but I'm sure someone else's free year of Sprint is ending and is in the same boat.
