You can put a basic phone on the Verizon Plan. Line access is $20, same as a smartphone. If you have no other devices that use data, you may want to cut back on your data to the lowest 2 GB since you won't need it like you did with a smartphone. That will save you $15. Make sure you turn on Safety Mode so if you ever do manage to use your data, you will not get an unintended overage charge.
