SOURCE: when i insert ethiopian telecom

Your mobile is not unlocked to work on international sim cards. Take your mobile phone to a mobile phone shop to get it unlocked for a small fee but I cannot guarantee they will be able to do this. as a last resort, contact your phones manufacturer. I hope this solves the problem.
