These calls from +441173068776 exhibit classic signs of nuisance harassment, with no messages left and suspicious line behaviour that locks devices. Such tactics aim to annoy or potentially probe for vulnerabilities. Block the number immediately to prevent further intrusions, and report it to your phone provider or the Information Commissioner's Office if it persists. Consider enabling call screening features on your device for added protection. Stay vigilant against unsolicited calls—never share personal details without verification. This pattern suggests automated or prank origins rather than legitimate contact.
A call came in without anyone speaking; when I tried to call back the number wasn’t recognised, so I blocked it.
When I answered, the phone subsequently locked because the line remained open.
A missed call left no voicemail, likely just a nuisance.
