Calls from this London number are frequently reported as spam, with a very high spam score. Most reports suggest the callers are impersonating mobile providers like EE, Three, and O2. They often claim your SIM card will be switched off or blocked, and ask for personal details like your email address to "verify your account" or offer a cheaper contract.

Anonymous Spam Mobile Network Scam (EE, O2, Three, Vodafone) 2 months ago

The first caller said he was from EE. They were going to send a replacement SIM because mine would be switched off. They wanted my email to check I owned the account. I told him it was a work phone and I wasn't the account owner. The second caller (same number) asked who my provider was. Seemed like there was some confusion in India!

One minute it's Sam from Three saying he can drop my phone bill to £3, and then the next he's saying "[profanity]Profanity hidden. Toggle off "Filter profanity" above to see the original wording my [profanity]Profanity hidden. Toggle off "Filter profanity" above to see the original wording" on the phone because I gave him a really obvious fake address! It was fun wasting their time :) 900% scam
