10 Disable Personalisation

22.0223GPPMobile functionality specificationPersonalisation of Mobile Equipment (ME)Release 17TS

There shall be a means to disable the personalisation at each level individually such that the ME shall operate with any (i.e. all) SIM/USIM at that level.

The process of disable‑personalisation can only be carried out on a currently unpersonalised ME, i.e., if the personalisation indicator for that level is set to "off". It results in the personalisation indicator remaining set to "off". When a particular level is disabled in this manner there shall be a means to make it impossible to change this status i.e. the disable becomes irreversible thus eliminating the need for key‑administration.
