Scammers can be very dangerous and it is important to take steps to protect yourself from them. One way to do this is to limit who can contact you on your phone. By going to the settings in your phone and selecting the privacy and security options, you can choose who can call you and who can add you to group chats. By setting these to "My Contacts" or "Nobody", you can be sure that only people you know can contact you, reducing the chances of being contacted by a scammer. Additionally, it is important to be aware of any suspicious emails or messages you receive, and to never share personal information such as bank details or passwords with anyone online.
