Message supposedly from OPTUS, wanting an update of my financial details, otherwise my service would be suspended. For one thing, it was an inaccurate account number. Be careful, and check with your provider.

I've received a text message from this number asking me to update my mobile account because there's a payment issue, but my bill is not due yet. And the link it provides is ended with .tel. Totally a spam.

don't have a NAB bank a/c so this must be a phishing scam
