Simsonic vs 1NCE: which IoT SIM fits your devices?

1NCE sells a low, fixed lifetime price for low-data IoT devices. Simsonic adds regulated voice, multi-network steering and SGP.32 eSIM. Here is how they compare and when each one fits.

1NCE and Simsonic both sell IoT SIMs managed from a platform with an API. They are built for different jobs. 1NCE is designed around a single low price for devices that send very little data. Simsonic is built for fleets that need voice, failover between networks and room to grow.

This comparison uses 1NCE's own published pages, checked on 28 October 2026. Prices and features change, so check the source links before you decide.

Where 1NCE fits well

1NCE's lifetime flat is simple and very cheap for the right device. If you have a small sensor that sends a few kilobytes a day, lives in one region and never needs to make a call, a one-off price with no monthly bill is hard to beat. Top-ups and lifetime extensions are available if a device needs more.

Where Simsonic fits better

Devices that need to call. Telecare alarms, lift autodiallers and alarm panels need a real voice line, especially as UK copper lines are switched off in January 2027. 1NCE describes SMS only. Simsonic carries regulated voice on the same eSIM as the data.

Devices that cannot go offline. Card terminals, EV charge points and safety equipment need to move to another network when one fails. The Simsonic IoT SIM is multi-IMSI and steers across 650+ carriers, falling back automatically.

Devices that use more data. Routers, cameras, telematics units and kiosks send far more than a small sensor. Simsonic plans are built around what the fleet actually uses, with pooled data and group caps.

Hardware built to last. If you want to change operator profile after deployment, SGP.32 eSIM for IoT is the standard designed for headless fleets.

Your own brand. Simsonic runs white label stores and consoles for businesses that sell connectivity to their own customers.

How to choose

  1. Does any device need to make a voice call? If yes, you need a provider that carries voice.
  2. What happens if a device is offline for an hour? If that costs you money or safety, prioritise multi-network failover.
  3. How much data will each device use over its life, not just this month?
  4. Will you sell connectivity under your own brand?

If your answers point to voice, failover or growth, talk to our team or run trial subscribers next to your current provider.
