UK scam guide · updated 27 September 2026
Scam calls claiming to be EE, O2, Vodafone or Three
A caller says they're from your network and offers an early upgrade, a loyalty discount or a SIM replacement. They ask you to read out a one-time code or confirm account details, then use them to order a phone in your name or take over your number.
What it looks like
- An unexpected call offering an early upgrade or a big discount
- “We've sent you a code, please read it back to confirm”
- A SIM swap or “network upgrade” you didn't ask for
- A parcel arrives and the caller asks you to send it back to a different address
- Calls from ordinary 07 mobile numbers
What the real organisations say
“we will never call, text or email you and ask for a one-time code, password, or other security information you've set up on your O2 account.”
“Three will never contact you and ask for your One-Time Passcode (OTP). Anyone asking is a fraudster.”
“Vodafone UK will never: • contact you to ask for your passwords or temporary passwords • ask you to read out a one-time access code”
“We will never ask for your personal information such as account details and passwords.”

Phone-network scam calls: FAQs
Would O2, EE, Vodafone or Three call me about an upgrade?
Networks do make sales calls, but none will ask you to read out a one-time passcode or your password. O2, Three and Vodafone all say so explicitly. If in doubt, hang up and call the number on your bill.
They sent me a phone and asked me to post it back. Is that a scam?
Three warns about fraudsters posing as its staff offering fake phone deals and then asking victims to return the phone to a fake address. Contact your network directly before sending anything.
How do I report a scam call claiming to be my network?
Share the number in a text to 7726 (Vodafone and Three ask you to type CALL followed by the number), and tell your network.
