My brother has type 1 diabetes, but he never has any problems. He told me, that he carries with him a paper from his doctor explaining what this device is, in case he falls into some freaks hands or through customs in a foreign 3rd world country where they never heard of a pump, so they can read about it on a doc's letterhead. I know that every doctor should have a template letter ready for you with explanation on the pump, some even have it in a few languages, like my brother that has it in 3 languages. Enjoy and don't worry.
