I've had first-hand experience where my phone just would not work. Because they weren't notified of my travel plans, they did not activate roaming capabilities.
As for informing the credit card company, it's so that your card is authorized for overseas purchases. If you don't do this, you may end up having to make a very long and expensive phone call whilst overseas to get everything sorted.

Wearing a money belt is not something I thought I'd ever wear but going on vacation to New York was something new to me. I'd heard that being careful included watching out for pickpockets so my new money belt fit is the answer. It holds my phone, money, cards, lipstick, tissues, keys. It's perfect and I can wear it as a fanny pack or under my clothes. Perfection.
