What you get

Made for hardware that lasts.

01

MFF2 form factor

A solderable chip that survives industrial temperatures, vibration and a 10+ year product life.

02

Remote provisioning

Load and change operator profiles over the air, long after the device is sealed and shipped.

03

Tamper resistant

The profile lives in a secure element, locked to the device and resistant to extraction.

850+carriers reachable
190+countries
99.9%platform uptime
How it works

Provisioned once it powers on.

Ship hardware with a blank or bootstrap profile and assign the real one remotely when it connects. Change carriers later without touching the device.

  • Industrial MFF2 (heat, shock, vibration)
  • Over-the-air profile management
  • GSMA remote provisioning
  • Locked to the secure element
// push a profile to an embedded eSIM
esim.provision({
  eid: "8900...41",
  profile: "global-iot"
});

Seal it once, provision forever.
