ONSIM AI text check

AI

This check analyses the message content, link domains and sender against known scam patterns. It is provided for information only and is not advice: see our terms and privacy policy. Personal details are removed before anything is stored.

What the checker looks for

Scam texts follow patterns. Delivery scams invent a small "redelivery fee" because a pound feels harmless - the real target is your card details. Bank impersonations manufacture urgency about a payment "you did not make". Family scams open with "Hi mum, new number" and build to a transfer request. The checker scores your message against these patterns, then goes further than the text itself: every link's domain is checked against the official registry for its age, because genuine organisations use domains that are years old and scam campaigns register theirs days before use. Include the sender and the number is checked against the same intelligence database behind our phone number checker, built from public sources and community reports.

Every check also makes the next one smarter: scam senders and domains feed back into the database (with personal details stripped first), so the tool improves as more people use it. Whatever the verdict, forwarding a scam text free to 7726 reports it to your mobile network as well.

Getting scam texts on your business number?

This free tool is built and run by ONSIM, a UK business mobile network. If your business number is the one attracting spam - or it is tied to one handset, or about to be stranded by the landline switch-off - that is the problem we actually solve: a virtual landline from £5 a month, or business numbers on a landline SIM, owned by the business.

Scam text questions

How does the scam text checker work?

ONSIM AI reads the message you paste and scores it against known scam patterns: brand impersonation, urgency and threats, requests for payment or codes, and family-impersonation formats. Any links are checked at the domain registry for how recently they were registered - a "Royal Mail" text linking to a domain registered last week is a strong scam signal. If you include the sender, the number is also checked against our number intelligence database, built from public sources and community reports.

Is it safe to paste a scam text here?

Yes. Pasting a message is harmless - danger only comes from clicking links, replying, or calling numbers in the text. We never visit the links in your message; domain checks use registry records only. Before anything is stored, personal details such as names, codes and reference numbers are removed automatically.

What should I do with a scam text?

Do not click, reply or call. Forward it for free to 7726, which reports it to your mobile network so the sender can be blocked. If it claims to be your bank or another organisation you use, contact them through their official app or website. If you have already clicked and entered details, contact your bank immediately and report to Action Fraud.

The checker said "no scam signals found". Does that mean the text is genuine?

No. It means our analysis found none of the patterns scams rely on - but clever scams exist, and no automated tool catches every one. If the message asks you to act, verify through the organisation itself rather than the message. We deliberately never label a message "genuine".

Why do scam texts come from ordinary mobile numbers?

Scammers send from SIM farms, rented numbers and spoofed sender IDs, and rotate them constantly. That is also why a number having sent one scam text does not always mean every message from it is a scam - and why we combine the message content with number intelligence rather than relying on either alone.
