I keep on getting calls from a call centre claiming to be Optus saying that they are able to offer me a 40% discount on my phone bill for 3 months. They just need my date of birth and a code. If you provide this, they send a code to your mobile phone which seems to be spoofing the OPTUSMSG name for SMS's. You are supposed to tell them that code to verify. I know this is a scam but I could see this tricking a lot of people. My question is, how can they spoof the Optus message or initiate one being sent and what exactly are they trying to do.
Hi @Joes, from what you have mentioned it`s definitely a scam call. You have done the right thing by not providing any of your personal details. With number spoofing the person / organisation calling you will display a different number from the number they are actually calling from. Basically they are pretending to be us (Scam) by making it look legit. So you might see an sms or MMS saying it is from an Optus number but actually it is not.
