[TarotChen]

current build number: 4
device name: turbo
channel: ubuntu-touch/rc/meizu.en

version version: 4
version ubuntu: 20160418
version device: 20160412-d272a77,

Steps:
1.Turn on sim pin
2.Reboot the device
3.Don't unlock the SIM but unlock phone screen
4.Swipe down the indicator and select network section
5.Tap on "Unlock sim" to bring up sim lock screen
6.Tap on "Emergency Call" button
7.Enter an emergency number and call

Actual result:
At step6, it shows regular dial pad with SIM locked header
At step7, "SIM card is locked" dialog appears

Expected result:
At step6, it shows emergency dial pad with emergency header
At step7, be able to make an emergency call

Error also can be reproduced with krillin and arale.

This works correctly on Arale and Krillin. I think the only problem is the header of the dialer says "Sim Locked" but I am still able to make an emergency call.

I think the fix should be to change the header text to "Sim Locked - Emergency Calls Only" or simply "Emergency Calls" with a sim locked icon.

Need design input here

I checked the code and the only case where the dialog is shown is when the number being called is not really an emergency number. What number are you trying to call there?
