Twenty dollars plus a plan. The cheapest way to try a second, dumber number.
$20 plus DUMBEST $15.99/mo, DUMBER $20.99/mo or DUMB $25.99/mo plus tax, 4-month minimum (required)
$20 one-time for the phone plus shipping, then a required plan with a four-month minimum. Three tiers, all plus tax: DUMBEST at $15.99/mo as a standalone phone, DUMBER at $20.99/mo as a companion to a smartphone, and DUMB at $25.99/mo which adds the Spotify, Apple Music and podcast bundle. Damage that is not an out-of-box defect carries a $65 replacement fee.

Notes
Signal, WhatsApp and text sync are linked clients paired to accounts you hold elsewhere, not standalone apps. Porting your old number cancels the service on your smartphone, so do not port it if you want this as a second phone. A factory reset means a replacement phone.
