Get your Tonga number

Open Microsoft
Go to account creation, or account.microsoft.com → Security → Advanced security options.
Enter the +676 number
Select Tonga (+676) in Microsoft's country picker, then paste the digits your dashboard shows after +676 into Microsoft.
Enter the Microsoft code
Microsoft sends a short numeric security code by SMS or voice call. SMS codes appear in your PhoneBorn dashboard next to the +676 number; type the code into Microsoft to finish.
