Comment 5 for bug 1375945

@Alfonso

Thanks for the detailed response.

With respect to other phones, the only other phone OS where I've used a locked SIM is Android. I'm pretty sure you it was possible in the past to skip the Unlock SIM screen and continue, but that doesn't appear to be the case with 4.4.4 on a Nexus 5.

AFAIK, the original Greeter design also behaved the same way, however I'm not aware of plans to change this before RTM, which means the user could end up in a state where they have a locked SIM in the device, and yet are still using it.

That said, I disagree with the comment about displaying an error that says "you need to enter a PIN first". "Enter PIN" and "Unlock PIN" both require the same PIN, so asking the user to enter the same string of digits twice doesn't make any sense.

As mako runs vanilla Android, I would also take it as the reference and claim that this should be quirked in the mtkmodem driver, or we modify the settings code to always perform both operations when unlocking the SIM.

I will invite Ken to our weekly network/telephony hangout and add this bug to the agenda.
