User reviews

pls add keyword filter/block function

Can help filter/remove those useless info/ad

Doesn’t Work

If it works, the scam rate wouldn’t hit this - Scam victims in Singapore have lost around S$3.8 billion since 2020, with a record S$1.1 billion in losses last year.

Useless apps

It’s not helpful at all since the phone number looks genuine. It can’t track a scam call that has been tag to a normal mobile phone number. Wandering what’s the point of using this apps if it has so much limitations in function!

Scammers are using caller id non display. Phone shows UNKNOWN number calling. But you cannot report UNKNOWN number in ScamShield
