How do I update Twitter via my phone?

I've been trying to update twitter via my mobile.

I have activated my phone and it's verified but I don't know what number to text updates too.

I've tried sending my updates too +447624801423 which is the number I activated my phone though, but it's not showing up on my twitter page.



I'm in Australia, is there a different number for each country? Or do I have to add a code into the actual text message?



I've tried looking through the help pages but I can't find anything.
