Short answer: On Tracfone / Straight Talk, your number is at risk after your Service End Date — or 6 months (smartphones) of no usage. Miss your Service End Date and the number is lost that day, even if you still have minutes.
How long you have on Tracfone / Straight Talk
If you keep a Tracfone / Straight Talk line you barely use, the number behind it is on a clock. On Tracfone / Straight Talk, the number is at risk after your Service End Date — or 6 months (smartphones) of no usage. Two triggers: your Service End Date, plus a 6-month (smartphone) / 12-month (other) no-usage deactivation even if a balance remains.
A working SIM that still shows signal doesn't mean the number is still yours — on prepaid, the number is tied to activity, not to whether the card powers on. (See what happens when you stop using a prepaid SIM for the full lifecycle.)
Can you get your Tracfone / Straight Talk number back?
Reactivate within 60 days to recover unused airtime, but you may be assigned a new number. Miss your Service End Date and the number is lost that day, even if you still have minutes. Once a number has been released to the pool and reassigned to someone else, it's gone for good.
What counts as keeping it active
For almost every carrier the rule is the same: it has to be something they bill — an outgoing call or SMS, paid mobile data, or a top-up or paid add-on. Internet apps like WhatsApp, iMessage and FaceTime run over data and usually don't count, and incoming calls and voicemail often don't either. The cheapest way to stay active is one small billable action before the deadline — more in how to keep a prepaid SIM active without spending money.
