What should be done with exchanged, used or faulty SIMs?
Edited
Exchanged SIM or Used SIM
Needs to be deactivated if the used SIM is not actively linked to a subscription or user anymore. Ensure that ICCID has no more plans / active connectivity attached to it.
Please note that once a SIM card has been activated it will not be possible to use it with another device.
Faulty SIM
Cannot be re-used and should be discarded.
End-user should discard these if broken or physically damaged.
