Contact AmbiSecure — talk with the engineering team.
This is the contact point for AmbiSecure's engineering team — the people who build the SIM-Auth Platform and the eSIM, eUICC, Secure Element, and embedded-PKI capabilities around it. Reach out for a partnership inquiry, a telecom sandbox collaboration, a technical discussion, or an enterprise and IoT security question.
The engineering team works across eSIM and eUICC provisioning (GSMA SGP.22 / SGP.32, SM-DP+, RSP), Java Card and GlobalPlatform secure-element applets, embedded PKI and X.509, and FIDO2 / WebAuthn authentication. Technical inquiries that name the standards and interfaces in scope get the most useful first reply.

What a first message should cover
The more precisely a message names the layer, the stage, and the constraints, the faster it reaches the right engineer with a useful answer.
The interface in scope
Which layer you are working at — eSIM / eUICC provisioning (GSMA SGP.22 / SGP.32, SM-DP+, SM-DS, LPA), Secure Element and Java Card applets, embedded PKI and X.509, or FIDO2 / WebAuthn authentication.
The stage you are at
Concept review, architecture evaluation, an operator sandbox, or a fleet already in the field. Scope and depth are sized to the stage rather than assumed up front.
The constraints
Target silicon, connectivity assumptions, certification requirements such as Common Criteria, and any regulatory frame the deployment has to sit inside.
How the engagement runs
Engagement is narrow, documented, and inspectable — the same discipline described on the telecom-integration and about pages.
1 · Documentation first
Architecture, applet behaviour, key inventory, and threat model are shared for reading before any code is exchanged.
2 · Bounded scope
Each engagement is proposed with defined inputs, outputs, and exit criteria rather than a broad early commitment.
3 · Operator-controlled sandbox
Validation runs inside infrastructure the operator controls, with operator-set boundaries, observability, and termination authority.
4 · Findings
Interoperability evidence and stated assumptions are returned so a security team can review efficiently and decide the next step.
Frequently asked questions
How do I start a technical discussion with AmbiSecure?
Use the structured inquiry form on this page and select the closest scope — partnership, telecom sandbox collaboration, technical discussion, or enterprise and IoT security. We respond within two business days, and for sandbox work we request additional context before sharing documentation.
Which channel should I use for confirmed delivery?
Email is the reliable channel — reach us at contact@ambimat.com for partnership and sandbox inquiries. We route technical discussions to the relevant engineer based on the scope you indicate, and we do not publish phone or instant-messenger contacts for inbound technical requests.
What kinds of requests will AmbiSecure not engage with?
We build secure identity, not workarounds. Requests that imply unauthorised access, SIM cloning, key extraction, or operator bypass receive no response, regardless of how they are framed.
How quickly does AmbiSecure respond?
Within two business days. Sandbox collaboration usually starts with a request for additional context before any documentation is shared.
What should an operator include to speed up a sandbox request?
The interface in scope (SGP.22/SGP.32, SM-DP+, applet layer), the stage of evaluation, target silicon, and any certification or regulatory frame the deployment sits inside.
