Definitely a Fraudster. I received an identical message saying it was: The account is locked, log in to the account for verivication. http://activation-commbank.mobi/cgi

Scam I don't even have a NAB account, & a Text came from this number 0424 696 724 at 5.43 am saying "Your account may be suspended and requires additional verification. "http://verification-support-nab.com/cgi"
Also received another text message to my phone from same number at 2.53pm which said "F#?k off ive given number to the police.

Think it is fishing for me to respond or swapping numbers??
