Roaming
Using a wireless phone outside of your service provider's local coverage area or home calling area is referred to as roaming. Roaming arrangements between service providers expand the potential area for phone use. Service providers typically charge a higher per-minute fee for calls placed outside their home calling or coverage area. Roaming within your home network, this means that your mobile phone automatically sets up communication procedures with different radio base stations when on the move. International roaming means that you can use networks other than your own when traveling abroad.
