I remember a couple of years ago I was able to use Amaysim to choose my own phone number. I just did a search and can't seem to find that option anymore. Does anyone know if it's still available? If so, what's the link? Or which other carrier can I use to shoose my own number for free?
Yes.
Unless you've already got a friend's referral, I suggest using the Ozbargain's random referral system
