The method is for selecting a telephone operator for mobile telephones. The mobile telephone has an operator card installed therein that has preprogrammed codes for providing communication via a first and a second telephone operator. A telephone number is then entered on the mobile telephone to activate the mobile telephone. A first request signal is sent to the first telephone operator and a second request signal is sent to the second telephone operator. The first telephone operator sends back a first response signal to the mobile telephone and the second telephone operator sends back a second response signal to the mobile telephone. A price request signal is sent to the first and second telephone operators. In response to the price request signal, the first telephone operator sends back a first price signal and the second telephone operator sends back a second price signal to the mobile telephone. The first price signal is compared with the second price signal and the first telephone operator or the second telephone operator is selected depending upon whether the first or the second price signal is the lowest.
