Requesting SIM unlock code for legacy Nokia 5250 (O2 Germany)

Hello O2 Support Team,

I have a legacy Nokia 5250 phone that was originally purchased from O2 Germany in the 2010s, and it is still SIM-locked to the O2 network.

I am currently living outside of Germany and do not have an active O2 Germany phone number or SIM card. Since the device is well past its original lock period, could a moderator please help me retrieve the free network unlock code for this device?

I have the 15-digit IMEI number ready and can send it via private message whenever needed.

Thank you very much for your help!

    Hi ​@surajpetwal000,

    Unfortunately, there isn't an English-language prepaid hotline, so I recommend that you wait for the o2 moderators here to respond. They can then take care of it.

    o2 has provided instructions in German on how to unlock your phone, which you can translate and use once you have the unlock code: https://static2.o9.de/resource/blob/69566/2b818b1f42f1947751206da5c277e553/entsperranleitung-nokia-pdf-download-data.pdf

    Best regards,
    Alex
