Confidence is high when the operator or the regulator states the date, medium when several independent sources agree, low otherwise. We recheck every month.
What it means for IoT devices on Sunrise
- 2G devices no longer connect to Sunrise. Trackers, alarms and meters that only speak GSM/GPRS need a 4G-based replacement, or a SIM that roams onto another network in Switzerland still running 2G.
- 3G fallback no longer works on Sunrise. Devices built for 3G (UMTS) or that fall back to it lose service; 4G devices with 2G fallback are not affected by this closure.
- For new devices, choose 4G-based technologies: LTE Cat-1 bis, LTE-M or NB-IoT where the network offers them.
- Foreign SIMs in Switzerland: we have not yet found a reliable source on permanent roaming. Details on the Switzerland page.
An M2M.global IoT SIM is not tied to a single network in a country, and its data can reach your cloud without the internet through private delivery.
