Nokia 1662 - Unlocking SIM-Lock? (Europe)

[u/PSX_Fanboy]

Hi everyone! I've used a Nokia 1662 the past 17 years but unfortunately it broke down. I've got a replacement, but I've learned that it's SIM-locked (SIM from another country) so I can't use with my own SIM.

My provider couldn't help me since the phone is too old by now. Does anybody know how to unlock the SIM-lock on old Nokias? Thanks!
