What's the relation between the server and the SMS verification when setting up the app? I haven't tried TextSecure in a while, but when I tried right after you announced TextSecure v2, I kept getting failure to send me the SMS, and I had to receive the robo-call. I had a friend from another country who experienced the same. Is that still a problem?

There were some capacity issues when the new version of TextSecure was first released. The SMS code is used to verify ownership of a number before it can be used for Push messaging.
