How long you have on Mint Mobile
That Mint Mobile SIM you forgot about can stop being yours sooner than you'd think. On Mint Mobile, the number is at risk after about 60 days suspended after a plan lapses. Mint sells 3/6/12-month plans; the 60-day suspended figure comes from secondary sources, so confirm it on Mint's own terms. This figure comes from a secondary source or isn't published as an exact day count by the carrier, so confirm it directly before relying on it.
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 Mint Mobile number back?
Reactivate within roughly 60 days to keep your number. After that the account is cancelled, the balance forfeited, and the number released. 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.
