Not sure what it is you're looking to do? A de-Googled phone running #GrapheneOS essentially takes you out of Google's data collection. The tricky part is to maintain confidentiality of your IMSI and IMEI...not sure how those are managed with a Tracfone, but both are mandatory, so both are present even with a Tracfone. If you get a SIM from a Tracfone, would you be able to either transfer that SIM to your Graphene phone? Or if offered by Tracfone, could you obtain a virtual SIM?
