Where emnify fits well
emnify has a broad radio range, including satellite plans for devices that work beyond mobile coverage, and its free SGP.32 bootstrap profile is useful for OEMs testing devices on the production line. If you are a hardware maker that needs data-only connectivity and satellite fallback, it is a strong option.
Where Simsonic fits better
Voice and data on one subscriber. Simsonic carries regulated voice alongside data, which matters for telecare, lift lines, alarm panels and any device that needs to make a call when copper lines are switched off in January 2027.
Selling connectivity under your own brand. Simsonic runs white label stores and consoles, so you can resell eSIMs, SIMs and data to your own customers under your name.
More than IoT on one platform. The same Simsonic console handles IoT fleets, business eSIMs for staff, travel data and private 5G and FWA, so one supplier can cover the whole estate.
UK focus. Simsonic is built around UK priorities such as the PSTN switch-off, with the same SIM working in 190+ countries.
How to choose
- Does any device or user need voice? If yes, Simsonic covers it on the same subscriber.
