Does this mean the ITU is going to assign the moon a country code? I vote for +6666 (MOON). Who decides what parts of the moon get what area codes? Imagine how long it will take to get Orange to instal a landline in a crater!
I like it, but +66 is Thailand already. It would probably get one of the available +87x or +88x codes. If they aren't just going to issue numbers from the home country.
Maybe Thailand could be reassigned. Like when Mexico dropped out of +1 to become +52.
Or maybe instead of +, we dial & to get off-planet.
