Have you tried not bringing a phone?

I'd be really interested in their response when you tell them you don't have one on you.

Seems like a good case for having a basic Nokia just for travel purposes.

As I said earlier....

Most companies of any size, and civil servants, have policies to travel with burner phones/laptops when crossing (even benign) international boarders; including into Australia and "the land of the free"

Frankly, it is so commonplace, it is not remotely unusual or suspicious to travel with a burner phone.

Or their response if you gave them your phone and pin but it's a wiped/reset phone.

Or their response if you didn't give them the passcode, and the data port is rewired internally.

I'd wipe my iPhone and restore from iCloud backup after the airport.
