Released 2011. Had 2003 on here!
I'm not up on unlocking these but in checking out the specifications it runs on Java firmware. Reports so far indicate that even unlocked Java phones display problems with these SIM cards.
I think you have 2 options. 1. Replace the phone. 2. Move to a network whose SIM cards will work with the phone in its present state. EE, BT, Plusnet, ASDA and 1p Mobile.
