Hello, today I changed my sim in my mobile and "Anti-Theft" asked me to enter my password. I cannot remember it. I have 2 mobiles, this one is a guest mobil and I think it's not registered as the other one is. The password for S5 works but this seems to be another one and I do not know what to do. Is there anyone who could help me? Plese?
