I will check this, but I remember that it is forbidden for at least two reasons: - the PIN can be changed (in another phone/application), and then it would be blocked this would make the pin cache feature also quite complicated, because it must be deleted when the presentation is wrong, and if the SIM is blocked, then also the application is more complicated because it must consider that it needs to unblock the PIN under some conditions. Also, if the PIN is changed by ofono, it must also be tracked by the caching feature. - the PIN presentation is prerogative and privilege of the user. It cannot be delegated to the ME. Otherwise there would be no need for a PIN at all. I have to say, I have seen several SIM with the PIN disabled (especially in the US), but the user can always enable it if he likes, and then wouldn't welcome that the device can be used without his consent. from an operator point of view, it attributes the responsibility to network access and use to the user, just like with the credit cards chip&pin. > > Regards, > -Denis _______________________________________________ ofono mailing list [email protected] https://lists.ofono.org/mailman/listinfo/ofono
