Caller: (07) 3493 5980

Just activated my SIM card hadn't even handed my number out and this phone number rings.
How do these people get a number you just set up?
Very concerning.
No privacy these days

Just received a call from this number. As soon as I answer they hung up. I suppose it is one of those marketing companies.

Same deal answer phone with no identity now added to my block caller list

This number just called me and left no message. No point calling back if all you get is a voice mail with no name. Usually marketing of some sort.
