If you're flying in, I'd recommend just bringing a cheap mod like a kanger subox or an Istick 50w. Had a foreign friend fly in and he did get caught, but played the clueless traveller card and nothing happened to him but he did have to surrender his mod. Also had some friends fly in without detection.
The risk is up to you. Just make sure if you do bring in something it's a mod you're willing to let go.
