Once out of range of the home, the CT2 user could find signs indicating a network base station in the area, and make outgoing calls (but not receive calls) using the network base station. Base stations were located in a variety of places, including high-streets and other shopping areas, gas stations, and transportation hubs such as rail stations. In this configuration, callers would be charged a per-minute rate higher than if they made calls from home, but not as high as conventional cellular charges.
