PSA: Scam Warning.
This is the third time in a week I’ve spoken to someone who’s had their phone stolen, then a few days or weeks later received an SMS or WhatsApp message with a malicious link in it pretending to be Apple/Samsung and they’ve found your phone.
Not real. They’re looking to sting you a second time, the theft was only the first part of the scam. They get your number from the SIM card, expecting you to keep your old number.
