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 Salt
- 2G devices no longer connect to Salt. 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 status unclear. Check on site before relying on Salt's 3G network.
- 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.
