The quickest way to search for a SIM is using Global Search in the SIM List. This searches a number of SIM columns without having to specify which columns. For more information please see What is Global Search?
If you know the column you want to search, or you want to search using a combination of criteria, then use Advanced Filter. For more information please see What is an Advanced Filter?
To clear the current filter, click the ‘Clear Filter/ Sort’ button.
