Roaming SIM cards from Caburn Telecom initially delivered a second layer of reliability and extra installation flexibility beyond an ethernet connection, but soon proved so easy to use and cost-effective that KoolZone adopted them as its primary connectivity method. “Having roaming SIM cards inside our gateways gives us several benefits,” explains Miller. “Firstly,we can activate connectivity instantly, even before the alternative ethernet connection is established. This is particularly useful in awkward, remote or hard-to-access deployment scenarios – or for sites with no available local area network (LAN).
“Secondly, combining roaming SIM cards – which automatically use the best possible network signal available – with wired ethernet means our customers benefit from almost uninterruptable connectivity. Data is accurate and available 24/7, with the roaming SIM and LAN connection serving as dual primary connection options if required.
“Hospitality businesses can ensure food and ingredients are the right temperature for customers and automate food safety compliance processes, while healthcare professionals have peace-of-mind that stored medicines are at a safe temperature and will work as expected.”
This connectivity protection is always important but especially so for KoolZone customers who need to provide temperature logs and other critical data for safety audits and regulatory compliance purposes. Caburn’s roaming SIM solution also helps KoolZone provide increased assurance to customers with vehicle-based refrigeration requirements, as the card automatically finds and uses the best available signal for mobile temperature monitoring and geolocation information whilst in transit.
The team also uses the intuitive Caburn M2M Insight platform, to manage its SIM estate. Individual cards can be grouped by a tariff, tagged with extra contextual information, and monitored for data and performance. KoolZone engineers can use the platform to activate new cards, change tariffs and suspend SIMs as needed. This remote maintenance and service provision saves KoolZone time and reduces cost.
Steve concludes: “We now use Caburn SIM cards across all of our new deployments. The connectivity has been so reliable that we’ve stopped worrying about the potential for any interruptions in temperature data streaming. We put the card in our gateway confident that the roaming SIM will keep the information flowing.
