> I used to live on a border and local EMS was 3-digit only. The only way to call the correct EMS was to call their non-emergency number and get forwarded - but only after getting scolded first for not calling the 3-digit number. I think there's a lot more code running on SIM cards these days to reduce/prevent that. On my Canadian Rogers phone, when I do a network scan, I don't see the american networks at all, but then when I put in a foreign SIM, they light up. Similarly, it can take a while of driving into the US before it detaches from the Canadian network and finally hands over to the US. It was actually an issue with my French SIM that was supposed to work in Canada and USA: it REALLY wanted to connect to the US networks, even though I was ~10 stories up in Toronto and very occasionally getting an SMS through once an hour to the US network.
