Manufacturers may enter into private arrangements to personalise MEs before delivery or at other times. They may also have the capability to de‑personalise/reset MEs for example, when a ME needs repairing, when the relevant control key has been forgotten or lost or if the ME has been blocked as a result of excessive failed attempts at de‑personalisation.

In all cases, secure arrangements shall be followed with the transfer and handling of the critical data such as the IMSI and the associated control keys.

In common with the normal de‑personalisation processes, the manufacturer controlled processes should be secure and be key or password controlled.
