I think that the sim security is active, you need to disable it with the security code.If you do not remember don't think that you can unlock byentering wrong code repeatedly coz the sim will damage.In case if you know the code Open >> menu >> Security>>Pin Code Request>> and turn it off by entering the code.But if you don' know the code contact mobile repairing shop because you could not fix it by yourself (You phone has no USB connection).Good luck
You don't know the security code? You can reset the phone using the master reset code,get the master reset code from the site Unlock-free.com and reset from security lock of NOKIA DCT or ALCTEL phones.
