Beware of fraudulent voice calls.

Recently some syndicates overseas have been defrauding mobile phone users using "missed called" method. How it works :

1. The overseas fraudster calls the victim (mobile phone user) from a Premium Rate Service number.
2. Fraudster hangup immediately after 1 or 2 rings.
3. Victim's phone registers a "missed call".
4. Victim thinks it is a legitimate call & then makes a return call. Victim is charged for the premium IDD call.
5. Fraudster earns revenue from the premium call.

Things to take note if you encounter such calls :

• Avoid calling back on an international missed call if you are not expecting such calls
• Immediately disconnect in case you call back on international premium rate number
• Do not share personal details
