There is a way to minimise your phone’s exposure to these scams.
Use your phone and give your prime number only to people you know and trust. Buy a $15 a year (decoy) sim card and put it in an old phone. When you are asked by the numerous businesses and contacts for your phone number but you know they will never phone you, give them your decoy number. Check it every few weeks and you will be amazed how many scam calls you’ve dodged.
Also, use a different email account for banking to the one you use for general use. A decoy email address is worthwhile too.
