Have changed my sim card on nokia 6600 and now just get a message "call now allowed" when trying to make a call.
Have security settings: lock if sim changed - yes. To change it to no it's asking for a lock code which i can't remember but know that it's not definitely the default 12345. can anyone help??!?!?!
Is the a way of finding out lock code/crack it or would restoring(and if so how can i do it) the whole phone help?
