No. If you currently have Tracfone service and you want to roll your current service days and minutes over and continue using Tracfone, you will have to purchase a Tracfone SIM card. You can get one from Tracfone.com, Wal-Mart or Wal-Mart.com.

I know that my local Wal-Mart sells Tracfone SIM cards, so a Wal-Mart close to you should sell them also. Walgreens may also sell them. You could also check local gas stations and grocery stores that sell Tracfone airtime cards and phones.
