What "Likely scam: Suspicious activity detected" means on your phone
A text arrived, and your phone put a red flag on it: "Likely scam: Suspicious activity detected." Nobody likes seeing that. But here is the good news first: that banner comes from your own phone, not from the sender. It is usually right. Here is what it means, and the few ways it can be wrong.
“Likely scam: Suspicious activity detected”
Google Messages adds this banner on your phone. It sits above the suspicious message, in the app's own frame. The sender did not write it and cannot see it.
How to tell
The banner comes from Google Messages, the texting app on your phone. It flags messages that fit known scam patterns: strange links, money asks, or a number posing as a company.
The warning is usually right. Google only shows it when the signs are strong.
But no banner does not mean safe. Plenty of scams slip through with no warning at all.
A "warning" written inside the message text is a different thing. Scammers fake official alerts. Your phone's real banner never asks you to call anyone or tap anything.
What to do
1Believe the banner. Don't tap any link in the message, and don't reply, not even "STOP."
2Tap "Report spam." It clears the message away and helps block that sender for other people too.
3Want a second opinion in plain words? Paste the message into CheckTwice and get an answer in seconds.
If you already clicked or paid
First: don’t blame yourself, and don’t hide it. Acting quickly matters more than anything else.
If you tapped the link but typed nothing, you are almost certainly fine. Close the page and don't go back.
If you entered a password, change it now on that account. Turn on two-step sign-in while you are there.
If you entered card details, call the number on the back of your card. Say you may have typed your card into a fake site.
If you replied, expect more texts. A reply tells them a real person reads this number. Keep using "Report spam."
Worth remembering: A warning from your phone is worth trusting. A warning inside a message is worth doubting. Where the warning lives tells you who wrote it.
