HOW DO ZARIOT SIMS CONNECT
AND PROTECT IOT AND M2M DEVICES?
eUICC SIM Cards
Available to push-out to mini, micro or nano size, they can be easily swapped in or out of a device which is useful if you are sourcing your hardware separately.

Widely used in
standardised
devices
Easily inserted:
adaptable to all sizes
Simply plug in,
enable, and use
Embedded eUICC SIMs
Sometimes called an eSIM, this is a surface-mount SIM that is permanently soldered to the circuit board of a device during the manufacturing process.
Prevents physical
SIM theft
Permanent
installation in sealed
or heavy duty devices
Simplify
manufacturing and
logistics with one SKU
Why eUICC?
eUICC is a software stack which allows for remote provisioning of mobile operator profiles over-the-air, effectively changing the mobile operator it ‘belongs to’ without changing the SIM card in a device. Although crucial for embedded SIMs, this technology is as standard on all ZARIOT SIMs.
