Thanks. I do have a spare phone and you can download partial maps on Kurviger so I'll give that a go if I continue with the app..If you can download the maps and set the app to ‘offline’ navigation, that should never be a problem again….. or at least much less of one.
I use MyRoute, its maps downloaded and the app set to ‘offline’ navigation by default. It runs on a sacrificial iPhone, with no SIM card, so it can’t receive a phone signal, even if it tried.
