| 主权项 | 1. A method for automatically switching from a Home IMSI to a Roaming IMSI and vice versa, said Home IMSI and Roaming IMSI being contained in a SIM card adapted to be used in a mobile station and adapted to comprise elementary files including an elementary file containing a list of forbidden networks which may not be selected, also known as forbidden public land mobile networks file (EFFPLMN), wherein the method comprises the step of triggering the switch from a first IMSI of the Home IMSI and Roaming IMSI to the other IMSI of the Home IMSI and the Roaming IMSI when detecting that the forbidden public land mobile networks file (EFFPLMN) contains at least one network not corresponding to the first IMSI. | ||
