Expert Opinion
If you get a call from +442046010651 and the person either hangs up quickly, repeats a polite greeting endlessly, or pretends to know your name, treat it as a potential scam. Hang up straight away and don’t call the number back – many of these lines are outbound‑only and will simply confirm your number to spammers. Block the number on your handset and report it to your phone provider or the national spam‑watch service. Keep an eye on any unexpected messages or texts that might follow, as scammers often try to lure you into a second contact.
