Thats fair. It's just how my own head canon explained that scene. I mean she modified a pager into a trans-galactic communicator. It's not a crazy thought that her soldier kit could do a thing like that. But! Still, your point remains. It hasn't technically shown those functions.
All the same, Im cool ignoring that feat from a reaction time perspective. Maybe I've got my signals crossed, but I sorta assumed that was the direction you were going.
