It's not being evasive about your electronics if you truly only have a travel phone while explaining it as a travel phone. That's telling it how it is.

If you have a phone and refuse to grant access, that's being evasive. If you have 2 phones and try to play it like you have 1 phone, that's being evasive. If you have a secret under-duress boot partition for your laptop, that's being evasive.

Having a set of travel electronics is not evasive. That's just how it is in today's big brother world.
