AI Summary
Based on 2 community reports
This 0333 number is linked to nuisance insurance telemarketing. Location is unknown and the call is carried by Voxbone SA. The spam score sits high at 75/100. Two community reports exist with no upvotes, describing persistent calls trying to sell insurance and push switching utilities. One report describes a very persuasive AI call that knew the caller’s first name and even suggested cutting electricity to force agreement—an alarming tactic. There are clear red flags but only a couple of reports, so confidence is low. If you receive a call from this number, hang up, avoid sharing personal details, and block it.

Tired of blocking the same company that sells insurance. They keep calling from different numbers even after I asked to be taken off their list.
Very persuasive AI call that knew my first name. Said they could help save money by switching utilities or white goods insurance and stuff. I mentioned I could save by cutting off my electricity, and it agreed but said I’d lose access to electrical appliances!

It does not prove that the registered owner of the number made the call or text. Community reports describe individual experiences and are not official confirmation of a scam.

Safety score
2 reportsHow this score was worked out
Each report rates the number as safe, unknown, suspicious or spam. The score combines those ratings, giving more weight to clear scams, and each person counts once. A number only reaches high risk once several people have independently reported it. Scores of 70% and above count as high risk, 40% to 69% as medium, and below 40% as low; a low-risk number reads Maybe Safe once someone reports it as safe. More about spam scores
