when I call some cell phones the caller ID shows my city and state rather than my name
You might try "Caller ID Per Call Blocking" (*67) to see if it will just block everything.
"Caller ID Per Call Blocking prevents your name and number from being displaying. on a per call basis". (That's a copy and paste from Cox's website. My high school English teacher would haunt me if I wrote something like that).
