@neil Do you know if the successful calls are over a 2G/3G signal, or using VoLTE (4G calling)? I understand the UK is in the process of shutting down 2G/3G networks, but not sure about that particular carrier at the moment. The issue in the USA is that 2G and 3G have been shut down, so VoLTE functionality is needed here. But I know things vary by country and even carrier.
We are shutting down 3G networks here, but our 2G networks will be around for a while.
@neil Ooh that is very interesting then. Are you on edge or stable image of pmOS?

@neil Thanks. This sounds promising.
@mpanhans I would have to guess at 4G, as this operator does not have 2G networks, and I was connected to a 4G network at the time.
