What it means for IoT devices in Switzerland
- Do not deploy 2G-only devices: every operator with a known status has switched 2G off.
- 3G is already gone on 2 networks: devices that fall back to 3G will lose service there.
- Private delivery works the same from Switzerland: device data reaches your cloud over private links. See private delivery.
