WhatsApp's widespread use as a customer service channel in many countries has created an opening for fraudsters posing as carrier support staff. Victims receive messages from numbers with carrier-like display names or from hijacked accounts, claiming to resolve billing errors, upgrade eligibility, or service outages.
Because legitimate carriers do sometimes contact customers via messaging apps, the initial approach seems plausible. Victims who comply with the 'agent's' instructions hand over everything needed to take over their carrier account and mobile number.
How this scam works on WhatsApp
Scammers send WhatsApp messages alerting the subscriber to a fabricated issue — an unpaid bill, a SIM registration problem, or a pending account suspension. The message includes a link to a phishing page or asks the victim to share a one-time code 'to verify identity.'
The OTP the victim is asked to share is often their carrier account login code or, more dangerously, a code that authorises a port-out request. In some variants, the 'agent' remote-connects to the victim's phone via screen-sharing tools under the pretence of troubleshooting.
Once they have credentials or a port-authorisation code, criminals transfer the number to their own SIM, then use SMS-based 2FA to break into linked accounts including banking and email.
Common red flags
- Unsolicited WhatsApp message from an unverified number claiming to be your carrier
- Request to share a one-time code or PIN 'for verification'
- Link in message leads to a domain that is not the carrier's official website
- Agent asks you to install any remote-access or screen-sharing app
- Message claims your service will be cut off within hours unless you act now
- Agent discourages you from calling the carrier's official helpline to confirm
- Display name includes carrier logo or official-sounding title but number is not verified
How to protect yourself
- Your carrier will never ask you to share an OTP via WhatsApp — treat any such request as fraud
- Verify any support contact by calling the number on the back of your SIM card or official website
- Never install remote-access software at the direction of an unsolicited caller or message
- Report and block the number immediately and check your carrier account for unauthorised changes
- Set a carrier account PIN and ask your carrier to add a note requiring in-store ID for port requests
- Enable two-factor authentication on your WhatsApp account itself to prevent account hijacking
How to report it
- Report the WhatsApp number by opening the chat, tapping the contact name, and selecting 'Report'
- Notify your carrier's official fraud team so they can warn other customers
- File a report with your national telecoms regulator or consumer agency
Frequently asked questions
My carrier contacted me on WhatsApp once — how do I know if it is real?
Legitimate carrier WhatsApp accounts are typically verified with a green tick. Even so, never share OTPs or account PINs. Call the carrier's official helpline to confirm any claim made via chat.
