You may wish to find a single SIM in the global fleet. But if you have a number of partner subaccounts, it may not be obvious how to do this. In fact, it is easy to do, using the global search option. First select the search tool icon:
Choose from the available filter types to use in the search, for example ICCID.
Then enter the ICCID for system you are looking for. Click the + icon to add the filter and start the search. The search will be applied across all partner accounts in the fleet.
