When a Windows Phone device is PIN-locked and I tap the "Emergency call" button, it brings up a dial pad. But when I try to call a non-emergency number, the following message appears:
So what numbers exactly are permitted for emergency calls? I'm guessing the ubiquitous 112, 911 and 999, but anything else? There are dozens of different emergency numbers in use around the world. What determines which ones are allowed? The OS? The carrier or SIM card? Something else?
Also, what if I move to a country where the emergency number is different? Or if the number in my country changes (not likely, but not unprecedented either)? Is there any way I can change the numbers that my phone allows dialling from the emergency call pad?
