Re: New Vulcan
Nothing's ever been said in the Prime timeline that there was no way of contacting the romulan government should the need arise.
Something changed... as Pike was able to recognize
Nero as a Romulan. In 2265, Spock said that neither side had visual contact with the other... hence the surprise when we see the Romulan commander in Balance of Terror
