eCall - is it likely to stop working for some?

[Fluffykins]

I'm in Australia at the moment, where there is a lot of steam and frothy water being made over the imminent shutdown of 3G mobile phone services.

I just wondered if anyone knows which network protocol(s) eCall uses. If it's 3G things might get juicy in the not too distant future.

In the UK it's the 4G network it uses. I can't see it being otherwise in other geographies.
