Calls from unfamiliar international numbers often turn out to be clever ploys to extract personal info. This one, flagged as unsolicited from Australia, screams potential scam—don't engage if it rings again. Hang up immediately, never share details like your bank info or address, and block the number on your phone. Report it to your local authorities or apps like Truecaller to warn others. Using call screening tools can filter out these nuisances, keeping your line safer from fraudsters hiding behind foreign prefixes.
While in Australia I got an unexpected call from +64 21 134 3938, which appears to be a scam and possibly didn't even originate from New Zealand.
