I assume, if that is intentional, it is a security measure.
It also seems to require a US number for receiving the verification code it wants to text you every time you swap the SIM card, making this a non-starter for international travel. (Well, unless you can manage to get it to text a Google Voice number or something. I haven't tried this.)

The iPhone version of the DIGITS app is extremely buggy, unfortunately. For example, attempting to manually dial a phone number is an exercise in frustration as the numbers get scrambled regardless of how carefully you enter them.
