Nobody seemed to answer you so I will try. I am NOT with Tracfone so don't know if they have any other requirements with phones. With that said - if your phone worked with T-Mobile it should work with Tracfone! The kit will include all sizes of sim cards; I would recommend you use a smaller card with the adapter only because it gives you an easier upgrade / sideways move to another phone. The only thing you may want to check is the frequencies Blackberry use vs. Tracfone but since you have used it recently with T-Mobile you should not have a problem. Also, the kit is only $1 dollar but I warn you about customer support with Tracfone - it is incredibly hit and miss, GREAT or REALLY bad!
