SIM SAFETY
OTP scams: recognise the request before sharing a code
Spot suspicious code requests, protect account recovery and respond quickly if you have shared a one-time password.

An OTP can authorise a login, reset, registration or payment. A person asking for it may sound helpful or urgent. Read the actual message to understand which action the code controls.
Common warning signs
Someone asks you to read a code back to cancel a transaction, receive a prize or keep your SIM active. The caller discourages you from hanging up. A message asks you to install a screen-sharing app before “verification”.
Verify independently
End the call and contact the provider using its official app or website. Do not rely on the caller's number or a forwarded screenshot. Enter a code only in a process you started and understand.
If you shared a code
Secure the affected account immediately through the provider's recovery route. Review active sessions and recent changes. Contact the operator if the line stopped working, and contact a financial provider if an unauthorised transaction may have occurred.
Stronger account protection
Use a passkey or authenticator where supported. Keep recovery methods current. A second factor helps, but it does not make a misleading approval request safe.
References and next steps
General preparation guidance is distinguished from operator-specific requirements. Confirm the requirements for your own transaction with the responsible provider.
