Purchased many years ago, this Motorola C118 was purchased specifically to be used on business trips to Europe. It went on maybe three trips.
No way to test it as there's no 2G GSM network in the USA anymore, but the battery holds a charge and the phone powers up and can scroll through menus.
Add a GSM SIM in a region where GSM is still active, and you've got a tiny little phone that works and makes cute little beeps. Comes with European-plug style charger which works on 110-240VAC.
BONUS: little carry pouch. This came attached to an old backpack. Good fit.
