Recently, the Macao Post and Telecommunications Bureau (CTT) found that the fraudulent groups are running rampant again. We have received public enquires about fraudulent SMS claiming from CTT and asking for credit card numbers to pay for the fees of registered mail with the number of RRxxxxxxxxxMO.  CTT reiterates that we will not ask the public to make payments through SMS. The public should stay vigilant, raise the anti-deception awareness and not to believe the calls or SMS from strangers in order to avoid falling prey to these traps.
