As echoed by everyone - 911 cannot be blocked by a provider, by law any phone capable of connecting (i.e. compatible frequency) must be given access.
The issue is most likely the device.
Both phones I've had were set to wind home manually.
When there was no signal, it would switch to rogers, but in emergency mode only. (no calls or texts would go in or out, except to 911)
Related note - for any family member who doesn't have/want a cell phone, give them any old one you might have for them to throw in their car/purse/etc in case they need 911.
