Some handsets now have built-in ringtone composers and some can download ringtones using PC synchronization software or via the wireless Internet.

Roaming a service offered by most cellular service providers that allows subscribers to use cellular service while traveling outside their home service area. The areas / countries you can roam in and the cost will depend on which service provider you use.

(If you require a phone that will operate in Europe, you will need a Tri-band phone).
