What it is

An eSIM is a SIM built into the device that can hold network profiles downloaded over the air. For IoT, standards such as SGP.32 make it practical to manage profiles across large fleets, avoiding site visits when a network contract changes.

Where it fits

  • Sealed or hard-to-reach devices
  • Large fleets deployed across many sites
  • Long-life equipment that may change network

What to look for

  • Which eSIM standard the device supports
  • How profiles will be managed
  • Coverage of each profile's network

See eSIM routers such as the Teltonika RUTX50 eSIM, our eSIM routers explainer and what eSIM is.

Part of our SIM and eSIM hub. You will find the products we sell for this below, along with our explainers. If you are planning more than a handful of sites, talk to us before you buy: getting the router, antenna and SIM right first time saves site visits later.

Talk to an M2M and IoT connectivity specialist. Not sure which technology fits your project? Tell us what you need to connect and where, and our UK team will recommend the router, antenna and SIM, with pre-sales advice, after-sales technical support and a range of configuration options.
