Fake Vodafone eSIM Upgrade and Roaming-Cost Warning Scam
Fraudsters send fake Vodafone notifications about mandatory eSIM upgrades or unexpected roaming charges, directing customers to phishing pages or charging for bogus plan add-ons.
Part of: Fake eSIM & Roaming Scams
Last reviewed: 7 June 2026
Vodafone has rolled out eSIM support progressively across its markets, making digital SIM management increasingly familiar to its customers. Criminals use this context to send fake eSIM 'mandatory upgrade' notifications that claim a customer's physical SIM will stop working unless they complete an eSIM migration by a specific date.
A separate scam targets Vodafone customers travelling abroad. A text message arrives claiming the customer has accumulated unexpected roaming charges that will appear on their next bill, and offers a 'retroactive roaming bundle' that can still be applied to cap those charges. The link leads to a payment page for a bundle that does not exist.
Both scams exploit the anxiety of mobile service disruption — either losing one's number or receiving a large unexpected bill — to prompt hasty action without verification.
How this scam works on the Vodafone brand
The fake eSIM upgrade message typically arrives by SMS and claims the recipient's SIM card will be 'deactivated on [date]' unless they scan a QR code or visit a link to complete the migration. The QR code or link leads to a fake Vodafone login page or to a page that walks the customer through a genuine eSIM QR code scan on a device controlled by the attacker — effectively installing the attacker's eSIM profile and giving them control of the number.
The fake roaming charge warning arrives while the customer is abroad or shortly after returning. It states that charges of a specific large amount have been incurred and that a roaming bundle can retroactively cap them if purchased within 24 hours. The payment portal captures the card details, and the bundle is never applied because it does not exist in Vodafone's system.
Vodafone's legitimate eSIM process requires customers to initiate migrations themselves through the My Vodafone app and involves scanning a QR code provided by Vodafone within the authenticated app environment — not via a link in an unsolicited text.
Common red flags
- Unsolicited SMS claiming your Vodafone SIM will be deactivated unless you complete an eSIM migration
- A QR code in a text message that you are asked to scan with your phone to 'activate' the new SIM
- A roaming charge warning from a sender that is not a recognised Vodafone short code
- An external payment link for a retroactive roaming bundle — Vodafone allows bundle changes in the My Vodafone app, not through external payment links
- Urgency: 'Activate within 24 hours or lose your number'
How to protect yourself
- Manage eSIM and bundle changes exclusively through the My Vodafone app or by visiting a Vodafone store
- Do not scan QR codes received in unsolicited texts purportedly from Vodafone
- Check your roaming usage and charges in the My Vodafone app — do not rely on figures in unsolicited texts
- If you receive a roaming charge warning, call Vodafone using the number on your bill to verify before making any payment
How to report it
- Forward the suspicious text to 7726 (SPAM)
- Report to Vodafone's fraud team via the contact details on vodafone.com for your country
- Report to your national cybercrime body if financial loss occurred
- If a QR code was scanned and a SIM transfer occurred, contact Vodafone immediately to reverse the eSIM assignment
Frequently asked questions
Would Vodafone deactivate my SIM without warning by text?
No. Vodafone does not deactivate SIMs via a last-minute urgent text demanding you scan a QR code. Any legitimate SIM migration is initiated by you in the My Vodafone app or in-store. Treat such texts as scams.
I scanned a QR code in a text claiming to be from Vodafone. What should I do?
Contact Vodafone's fraud team immediately. If the QR code was an eSIM profile install prompt and you accepted it on a device, your number may have been transferred. Vodafone can reverse this and secure your account.
