Negative-Option Billing Scams on WhatsApp
Fraudsters use WhatsApp to promote 'free trial' offers that secretly enrol victims in recurring subscriptions, with cancellation terms buried in fine print or entirely inaccessible.
Part of: Negative-Option Billing Scams
Last reviewed: 1 June 2026
Negative-option billing scams arrive on WhatsApp as promotional messages offering free products, health supplements, or digital services — all the victim needs to do is cover a nominal shipping or activation fee. Hidden within the offer are terms that enrol the victim in a monthly subscription charged to the card used for the initial fee.
WhatsApp's personal, conversational tone makes these messages feel like friend recommendations rather than advertisements, reducing the scepticism that might apply to unsolicited emails. The chat format also makes it easy for scammers to answer specific questions, reinforcing the impression of a legitimate business.
How this scam works on WhatsApp
A WhatsApp message promotes a free trial of a health product, software subscription, or beauty box. The call to action asks the recipient to tap a link and enter card details to cover a small delivery charge. Once the card is saved on the fraudulent merchant's system, monthly charges begin — often slightly varied in amount to evade automated card fraud detection.
When the victim queries the charges, customer service contact details prove unresponsive, invalid, or loop through automated systems without resolution. Cancellation may require a process the victim cannot complete — an account login page that does not work, or a phone number that rings indefinitely.
Some operators use WhatsApp Business accounts with professional-looking profiles and product catalogues to add legitimacy.

Frequently asked questions
How do I stop recurring charges from a negative-option billing scam?
