Will SAM unlock tickets still work if I change phone numbers but maintain the same sim card and same provider?

Yes, your SAM unlock tickets will continue to work if you change your phone number. The Subscriber Artificial Module (SAM) unlock method relies on the unique identification details of the physical SIM card itself, such as the ICCID and IMSI, rather than the phone number assigned to the account. As long as you are using the exact same physical SIM card and staying with the same cellular provider, the activation tickets remain valid. If you were to switch to a different physical SIM card, the unlock would fail because the ticket is cryptographically tied to the unique hardware ID of that specific SIM.
