Sims are free from Verizon stores but not from the Verizon no name retailers.. I took the person's word for it.. but u can always ask for the esn and look it up.. I forgot the website that I used to check the esn for free in the past but u can look around Google for it.. u always wAnna make sure it's a reputable seller on any site with things they've sold in the past.. not just what they bought.. there's definitely a lot of time and effort that goes into finding the right seller with the right price
