Not sure why you would get "shut down" mid way through your trip unless you are doing crazy things like adding a ton of AUs or other odd things (And not sure why you would do that while traveling on random wireless networks). Let them know you are traveling and you are fine. "Random" FRs are sprung by oddities. Traveling around and purchasing things like food, hotels, etc are not one of them.
My "random" FR came from adding 15 AUs in one night prep'ing for SBS.
