Abstract
A digital mobile terminal 201 is operable in two modes. When a call is to be set up, i.e. an off-hook signal is detected, the terminal first attempts to communicate in a private mode with a private base station 203. If this fails, i.e. no connection is made within a time period set by a timer, then the terminal switches to a public mode. The terminal attempts to communicate with a public base station 202 in a public mode until another time period expires. In this way, cheaper rate calls are always attempted first even if a user forgets to change the position of a mode change switch from receiving calls in the public cellular system.
