An engineering company, not a pitch.

Who we are

The eSIM Initiative is operated by the embedded engineering team at Ambimat Group, under AmbiSecure — the Ambimat Group's embedded security and trust initiative. The Ambimat Group is an India-based engineering organisation with over four decades of work in embedded systems, hardware/software integration, IoT, and connected products. We focus on the substrate that connected devices rely on for identity: Secure Elements, eUICC silicon, applet engineering, and the trust chains that connect them to operator networks and enterprise back-ends.

What we believe

We believe most failures in connected systems are not exploits — they are quiet identity failures. A device that ships with a shared credential, a cloud back-end that cannot tell two devices apart, a provisioning step that delegates trust to an environment that doesn't deserve it. We design to remove those quiet failures, not to add features on top of them.

We believe credibility in this space is earned by being reviewable. So we document our architecture, our applet states, our key inventory, and our assumptions — and we are willing to be evaluated by people whose job is to find the weak link.

What we are not

We are not a startup looking to disrupt telecom. We are not a security-marketing operation. We do not claim certifications, partnerships, or production integration that we have not earned. The most useful thing we can do for an operator review is to be specific about what we are not, so that what we are can be evaluated honestly.

• We are not GSMA-certified.
• We are not currently integrated with any production MNO.
• We do not perform Ki/OPc extraction, SIM cloning, or any form of unauthorized provisioning.
• We do not claim "telecom-grade" as a label — we claim it as an aspiration we work toward, transparently.

How we work with partners

Our preferred shape of engagement is narrow, sandbox-oriented, and inspectable. We share documentation early. We propose well-bounded validation scope. We treat operator infrastructure with the seriousness it deserves. We expect — and welcome — the kind of review that a serious counterparty would apply to any new vendor in this space.

Where we operate

The eSIM Initiative is operated by Ambimat Group through Ambimat Group, headquartered in Ahmedabad, India. Our scope is global where eSIM, eUICC, and embedded identity are relevant — with particular interest in collaboration with telecom operators and ecosystem participants who are open to engineering-led, sandbox-based validation.
