Comment 21 for bug 721106

SIM cards come PIN-locked by default over here, and there is no out-of-the box way of unlocking it without inserting it into a phone that is capable of doing so. NetworkManager does not store the PIN in the keyring, so there's a PIN prompt at every login. Actually, there are currently two PIN unlock dialogues, a small one, a larger, more descriptive one, and a small, plain one. Without auto-connect, I get the larger PIN unlock dialogue at login, and the smaller one if I try to unlock the device later on. Sometimes, it appears to me that both are created at once and one tries to close the other, but that does not impair functionality.

The idea of setting the connection of auto-connect was to enter the PIN and have NM connect automatically afterwards, now it's two more clicks.
