The Independent outlines methods to combat unwanted and scam phone calls in the UK. Key strategies include enabling phone settings like Apple's Silence Unknown Callers or Android's block features, blocking individual numbers, and using the Telephone Preference Service (TPS) to reduce marketing calls. Third-party apps such as Nomorobo and YouMail can help block spam calls. Revoking consent for robocalls and avoiding engagement with suspected scams are also advised to prevent fraud.
