In what countries does 1NCE offer connectivity?

On principle, the 1NCE footprint extends across all EU28 countries, as well as Norway and Switzerland. In these countries, 1NCE SIM cards can transmit data on 2G and 3G networks. NB-IoT is currently only supported by wireless providers in select countries in Europe, hence NB-IoT is only available scattered across the 1NCE footprint. A comprehensive list will be available soon.
