You can keep a phone number as long as you like. If you accidentally delete it or allow it to expire, then we can probably, on a best-effort basis, recover the phone number for you if you alert us quickly after you make the mistake. Once we have done a resupply of the SIM card pool the SIMs that have been used and are no longer in use are destroyed, at which point we can't get the number back for you.
