Can I sign up if I'm based outside Australia?
You need an Australian mobile number to sign up, because the main account's login codes are sent to it by SMS each time you log in. We can't verify an account another way or set one up manually.
The account also has to be for an Australian business or organisation. We can't open one for a business based outside Australia, even if it has an Australian mobile number or only sends to Australian numbers.
If you build or run SMS for Australian businesses from overseas, your clients can sign up for their own accounts. People outside Australia can then be added as users under Settings > Manage Users, with login codes sent to their email.
We only send to Australian mobile numbers. See Can I send SMS messages to international numbers?
