access PUK codes for old mobile phones with 02 ireland sim card

any advice accessing PUK codes for old O2 network Ireland phone?

i recently found an old box in the attic with all my old mobile phones- would love to sell/dump/ donate them but want to wipe them first. Having difficulty with an old siemens MC60, its asking for the PUK code. i long dumped the card that came with the sim, its locked to 02 Ireland which doesn't exist anymore.

Cant access the IMEI as cant progress past the PUK screen. I have the sim, the box it came in but thats it- is it a lost cause?

Not sure if it will work, try three SIM, O2 is owed by three.

PUK is SIM unlock code , not phone.

Old phones have label under battery with IMEI printed
MC60 box, but phone itself seam different model (C65 perhaps) and could be on different network altogether
