RESTRICTION CODE NOKIA 6288

its not good news the phone is blacklisted in the united kingdom which is why the phone was locked to Telstra as soon as it was brought back into the united kingdom the blacklisted phone company has restarted the blacklisted barring and hence froze the phone.
before despairing try a few things first try taking to a mobile phone shop and ask them to unlock it if they refuse take it to a market stall mobile phone unlocking stall and they will do it for you however if the phone is blacklisted/barred in the united kingdom you will not be able to make or receive calls. and they do charge. try taking the chip out and booting the phone up without the sim card in and changing the network settings and see if that works .hope this helps

Contact your network provider, they might ask for a fee for unlocking it but its done properly and they send YOU the detail via the post and its VERY easy to do.
