Unable to unlock phone

Lookout

Trying to unlock Samsung Galaxy J3 (2017) set, received unlocking code from Three, when I insert SIM card from another network into set the following message pops up:

SIM network PIN blocked. Enter SIM network PUK.

Tried to enter both PUK code of new SIM card and unlocking code received by Three, but no luck.

@GB78 thanks for getting in touch 👍 I'd recommend contacting your new provider to query the SIM you got off them, as none of the PUK's is working for you that's something specific to the SIM. If you were getting an error after entering the Network Unlock Code, let me know. Shauna 👍

Hi @Three_Shauna, tried to unlock set using a different SIM card and same message popped up. Entered unlocking code provided by Three, but to no avail.

@GB78 is it giving you an error when you put in the Network Unlock Code?

Network unlock request unsuccessful. I entered the same SIM card into
another unlocked set and it is working fine.
