A method is disclosed of switching the active subscriber identity of a communication terminal which is capable at each moment in time of having only one active subscriber identity. An active subscriber identity switch from a first subscriber identity to a second subscriber identity is initiated. At least one parameter associated with a time of expiry of a timer associated with the first subscriber identity is stored. The first subscriber identity is deactivated and the second subscriber identity is activated. If an active subscriber identity switch from the second subscriber identity to the first subscriber identity is initiated and the first subscriber identity is activated, it may be determined whether the time of expiry of the timer associated with the first subscriber identity has passed. Network registration of the first subscriber identity may be performed only if the time of expiry of the timer associated with the first subscriber identity has passed. Corresponding computer program product, controller, arrangement and communication terminal are also disclosed. |
