Modernize IoT hardware with eSIM and iSIM technology

Streamline your PCB, improve durability, and simplify global logistics with solderable eSIM and integrated iSIM options—backed by Soracom connectivity and lifecycle control.

Remove the SIM tray and simplify your design

Standard SIM cards work, but the connector, tray, and insertion steps add size and risk. With soldered or integrated SIM formats, you reduce mechanical failures, protect credentials, and ship hardware that’s ready for industrial environments.

Save board space

Eliminate the SIM slot and tray to free up room for sensors, batteries, or smaller enclosures.

Improve durability

Avoid moving parts that can loosen under vibration or fail in dust and moisture.

Reduce tampering risk

Once soldered or integrated, SIM credentials are far harder to remove or swap.

Speed up manufacturing

Remove manual SIM insertion steps during assembly and device kitting.

Simplify global logistics

Build one hardware design and manage connectivity profiles as you deploy worldwide.

Explore embedded and integrated SIMs

eSIM is the proven standard for rugged deployments. iSIM pushes miniaturization further by integrating SIM functionality into the modem.

Solder in Soracom eSIM for rugged, long-life devices

Soracom eSIM uses the MFF2 form factor—an industrial-grade chip you solder directly onto your PCB during manufacturing. That gives you a durable SIM footprint designed for long lifecycle deployments and harsh environments.

Fit industrial builds

No tray to break, no contact pins to corrode, no accidental SIM ejection.

Reduce field failures

No tray to break, no contact pins to corrode, no accidental SIM ejection.

Keep hardware consistent

Design once, then manage connectivity through Soracom as you expand globally.

Integrate iSIM to shrink hardware even further

Soracom iSIM moves SIM functionality into a secure element inside the cellular modem’s SoC. That means no separate SIM component, fewer interfaces, and more room for ultra-compact or low-power product designs.

Use iSIM when size, power, and BOM are the constraint

Shrink the footprint

Save space beyond eSIM by removing the separate SIM package entirely.

Lower integration overhead

Reduce components and interfaces by keeping SIM functionality inside the modem.

Simplify sourcing

Cut one part from your BOM and streamline manufacturing procurement.

Manage eSIM and iSIM fleets the same way you manage physical SIMs

Soracom lets you organize devices into groups, apply policies, and manage connectivity at scale from the Soracom Console and API. As your product grows, you keep one operational model—whether the SIM is removable, soldered, or integrated.

Frequently Asked Questions

What’s the difference between eSIM and iSIM?
eSIM is a soldered SIM chip (MFF2) added to your PCB. iSIM integrates SIM functionality into the cellular modem’s SoC, removing the separate SIM component.
Do eSIM and iSIM change how connectivity works?
The goal is the same: authenticate the device and connect to mobile networks. The main difference is hardware form factor and how you build the device.
When should I use a physical SIM instead?
Physical SIMs are ideal for prototypes, developer kits, and gateways where swapping SIMs is useful during testing.
Is eSIM more rugged than a removable SIM?
Yes. With no tray or contact pins, soldered eSIM designs are better suited for vibration, dust, and moisture.
What networks are iSIM modules typically used for?
iSIM is commonly paired with LPWAN designs like LTE-M and NB-IoT where size and power efficiency matter most.
Can I use Soracom with all SIM formats?
Yes. Soracom supports cellular connectivity and lifecycle management across removable SIMs, eSIM, and iSIM—depending on your hardware and deployment needs.
