The invention relates to a method for automatically configuring a mobile device such as a mobile phone with service parameters provided by a network operator. In order to receive the service parameters the mobile phone needs to connect with the network operator associated with the SIM card which the mobile device has been configured with. However, it may be difficult to make this connection since the SIM card does not uniquely define the network operator. According to an embodiment of the invention the network operator is identified or suggested based on databases containing information of names or alternative names of network operators and probabilities indicating a likeliness that a network operator may be the operator associated with the SIM card.
