Here's strip 28 of Dude in Distress, and--as if his night hadn't already taken a turn for the worse--Clark finds his phone blowing up with calls from the dreaded "Unknown Caller."
Custom app for her phone that lets her keep her number private while making it clear she's not a telemarketer? Or does the local super organisation have a member with tech powers whose job is just to track down phone numbers of people supers meet and want to chat with or people who are known targets of villains?
nice touch, a simple direct transmission without going through a normal cell net means that you can alter your id on the fly and ensure your number stays somewhat hidden even if the phone company is hacked. not what i expected, which is another plus.
