AI Summary
Based on 2 community reports
Calls from this number 01484 509476, carried by Gamma Telecom Holdings, look like a SIM-swap scam. The report describes a caller posing as EE, trying to start a 5G SIM upgrade and refusing to email. The script matches known fraud patterns: claim your SIM is outdated, push a 'free' replacement, then request an OTP text and your email. If obtained, the criminals can perform a SIM swap and potentially access bank accounts. There are no upvotes or downvotes yet, so confidence is limited. Trading Standards have warned about criminals posing as network operators around 5G upgrades. If you’re contacted by this number, hang up and never share OTPs, codes, or personal details; verify with EE or your carrier through official channels.

Caller claimed to be EE . Tried starting "order process" to upgrade my SIM to "take 5G". Declined to email me. AI says "EE has confirmed it does not do this.This is a scam. EE's 4G service is still active, current 4G SIM cards already work with 5G, and "EE don't have a programme in place to proactively contact customers to replace SIM cards." Trading Standards issued a warning in August 2026 about criminals posing as network operators and exploiting interest in 5G upgrades. The typical script matches what happened to you almost word for word: a cold call claiming your SIM is "outdated" or can't handle 5G and must be replaced (usually "free of charge"), followed by an attempt to "start the order." Their goal is a SIM swap (account takeover).They "start the order," generate a genuine one-time passcode (OTP) text to your phone from EE; ask you to give it and your email address. If you do, your phone number goes on their SIM card. They can then access your Bank Accounts!

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
Why this number is rated Medium Risk
