What is an eSIM?

An eSIM is a single SIM card that provides the ability to remotely switch carriers or cellular technology, such as 2G, 3G or 4G, for IoT devices deployed over a long period of time.

Switching is achieved via Over-the-Air (OTA) commands sent to the device versus physically switching the SIM card.

Benefits include the ability to prevent technology or carrier lock-in and streamline logistical efficiencies.

Traditional SIM Card

Traditional SIM

  • Carrier-specific & contains only
    one carrier profile
  • Carrier profile cannot be replaced remotely
  • Physical SIM swap is required to
    change network carrier
  • Different SIM for each carrier


  • Carrier or OEM-specific but can support multiple carrier profiles
  • Remote download & management of
    additional carrier profiles
  • Eliminates physical SIM swaps – over-the-air profile management
  • One SIM for multiple carriers
