How to Use a Tracfone SIM Card in Another Phoneby Greyson Ferguson ; Updated September 28, 2017
When using a cell phone with a SIM card, all the user information and contacts are saved directly to the SIM card. Without the card inserted, the cell phone is not able to function. It's possible to remove the SIM card from a TracFone and insert it into a different SIM-based cell phone. Doing so allows you to use your TracFone minutes on just about any phone that requires a SIM card as the phone now reads the contact information stored on the newly inserted card.
Remove the SIM card from the TracFone. The location will differ depending on the TracFone model you are using, but it is usually found behind the battery.
Open the phone into which you want to insert the SIM card. Again, the SIM card slot location will vary from model to model.
Remove the battery before inserting the SIM card (even if the SIM card slot is not located next to the battery compartment). You need the phone completely powered down when switching out SIM cards.
Insert the TracFone SIM card into the open slot, then place the battery back into the phone and turn on the device. The new cell phone now detects the TracFone SIM card. When you dial a number the minutes are subtracted from your TracFone account.
