You could also call this "Free Nexus5 if you switch from AT&T or Verizon." Here's a comparison of the plans and how I arrived at the idea of "Free" Nexus 5.
|Phone purchase price||Subsidized $200 every 2 years||No subsidy|
|Monthly cost for 2 lines||$190||$90|
|Data||Unlimited originally, switched to 2GB for the same rate||Unlimited (2.5GB cap, after that 3G service)|
This chart shows how much money both of these plans cost. I used a MotoX as the subsidized phone since it is similar in specs to the Nexus 5.
For our 2-phone-household, we had been spending $4,658 in a 2 year cycle compared to our annual of $2858. Both of those numbers feel pretty high, but at least with StraightTalk we're saving $1,800 in a 2 year cycle. Source data for that chart is in this spreadsheet
Let me say that again: $1,800 savings in a 2 year cycle! We could actually buy a new Nexus phone (or similar) every year and still save money compared to Verizon.
