Tracfone BYOP (Bring Your Own Phone) is limited to a subset of older Verizon phones. The iPhone 4 and 4S are allowed but BlackBerrys aren't and neither are LTE-capable phones, which eliminates all Verizon smartphones released in the last couple of years.
BYOP uses the same "triple-triple" billing system as TracFone's recently introduced Android phones. The way it works is that a $19.99 "60 minutes" refill gives you 180 minutes, plus 180 texts plus 180 MB of data good for 90 days. When you add more money unused minutes, texts and data "roll over" and get added to the total available for the new plan period.
Triple-triple is quite a deal, especially for data, when compared with TracFone's older feature phones which only tracked minutes and deducted 1.5 minutes for every KB of data used. With triple-triple, assuming you could use all three buckets at an equal rate, the per unit price of a minute, text or MB of data ranges from 3.7ċ with the $19.99 60 minute card to 2¢ with the $79.99 450 minute card.
The only downsides to triple-triple are that unlike with TracFone's own non-smartphones, there's no roaming and it's not a very good deal or users who mainly use text messaging rather than voice calling or data.
To activate a Verizon phone on TracFone go to tracfonewireless.com/byop/ where you will be asked enter the phone's MEID serial number. If the phone qualifies based on the MEID you get to purchase a $9.99 "Network Access Code" which allows you to active your phone online.
Updated 03/07/204: TracFone's BYOP site now says they can activate the iPhone 4 and 4S.
