Example: A company lends SIM cards to its employees and wants to restrict outgoing calls to members of the same team. If you select the Closed User Group menu, you can enter the CUG function. You can now access the following options: • Index List: lets you list, add, or delete CUG index numbers. If there is no CUG index stored, you are prompted to add a new index when you select this option. Once you have added a CUG index, the list of current CUG indexes appears. Add a new CUG index as advised by your service provider, or delete a group. • Outside Access: lets you enable or disable calls to numbers other than those in the CUG.
