tcad​ is correct.  Flip phones and other basic phones most often have no SIM card or an embedded SIM card.  A basic phone would have to be a branded phone to work on Verizon.  ATT and T-mobile phones have no CDMA bands.  20 minutes and $50-70 bucks will get you a compatible phone Off Amazon.  Up to $200 if you buy a current flip from Verizon.
