SIM unlock

Hello O2 Team,

I have an old O2-contracted flip phone, an LG G5400, that I would like to SIM unlock.

Could you please assist me in retrieving the unlock code (Entsperrcode) for this device?

Device Model: LG G5400

IMEI: XXXXXX

Thank you very much for your help!

Best regards,

Hinako

Hi @Hinaaa

welcome to our community. Pleasure to meet you here. 🙂

Unfortunately we don’t have the SIM Delock code anymore. The phone is too old.

I’m sorry.

Greetings
