@bLaZeR666_uk I’m not even sure if it is possible to unlock that device as you have no interface to enter any code into it but you could try calling customer services and see what they say. It could even be a OTA unlock. But try putting a different network sim in it first to see what happens.
To contact EE Customer Services dial 150 From your EE mobile or 0800 956 6000 from any other phone.
