Thank you for your replies. I am a very limited user of our smart phone. I have it primarily to be able to use in the event of an emergency, and the only app I use regularly is Drive Safe & Save thru State Farm to get a discount on auto insurance. The app recently updated and now requires at least OS 9. If I were to get a new phone, the ones I am looking at use either Android 11 or 12. With a new OS update every year, I might have a few years before a new phone would be outdated as well if the State Farm raises it's minimum OS requirements. Not being an avid cell phone user or very tech savvy, IF my current phone could be unlocked (which seems to be an option from Tracfone), and IF the OS be updated to a newer version, my needs would be met. My current phone does all I need it to do at the moment, except be able to run that app, so am not anxious to have to get a new phone and have to transfer contacts, etc. Even if I get a newer phone, I might face the same dilemma again with needing to update the OS. I want to stay with Tracfone service because of all of the unused minutes, texts and data I have accumulated over the years and can transfer. So, back to my original question: Can the OS be updated on an unlocked Tracfone? And, a second question: If I were to get and bring my own phone (one unlocked and not sold by Tracfone) to Tracfone, would OS updates be easier and possible?
