I've always got these pesky marketers randomly messaging me, whether it's some scam, newly launched property, investment product or broadband package.
Whether people know or not, our phone numbers are being sold in packages to different groups. There's packages of high net worth individual, packages of owners of a certain condominium unit etc.
Most people would just block the phone number if the content wasn't interesting.
I learnt this from a marketing sifu , he taught a technique to try to monetize these marketers number by packaging it myself and then re-send all my referral codes, stuff I'm selling on Shopee etc.
