Interesting discussion caught my eye today about maintaining Australian mobile numbers while overseas, particularly for those essential OTP messages we can’t seem to escape. The quest for the most economical solution definitely resonates with my bargain-hunting spirit.

The whole two-factor authentication landscape has become increasingly complex since then, with everything from banking to MyGov requiring that precious mobile number. It’s fascinating how our phone numbers have evolved from simple contact points to crucial digital identity anchors.
