Unlock Simlock at O2 - Here's how

When a mobile phone contract is signed with O2, the associated mobile phone is provided with a simlock. So you can only use O2 SIM cards. After 24 months, this lock expires automatically and you can use any other SIM card with the device.

• To do this, log in to My O2 and switch to "My tariff / SIM card".
• There you will find detailed instructions on how to unlock your phone.
• If you want to remove the lock before the end of the 24 months, contact the O2 customer service.
• Then enter your IMEI number of the device there so that it can be activated.
• This process then costs you around 100 euros. Automatic unlocking after 24 months is free.
