I've posted this to Geekzone too, so forgive me if this a double up for some.
I have a quirky question that I'm forwarding on behalf of a client:
"My caller ID comes up with my number in NZ, but when I call someone in Oz it comes up as 'private number'. Why do you think that is?"
I've had her check ID blocking on her iPhone 8, but all appears correct. What am I missing?
Best answer from Geekzone is 'Cause the CLI must be stripped out by the carrier in OZ'
