methods to help remove the security risk
Avoid clicking on any UNKNOWN messages with links. Furthermore, think about who sent you the message. Is it a person that you know?
Do not reply to text messages that have asked you about any of your personal finances.
If the message states " Dear user, congratulations, you have won...." It is a clear sign for smishing and let's be real, nothing is life is free”.
