Joseph Callahan’s 5 September 2026 company declaration states Keyra builds on more than 15 years of Ciright Cyber One Card experience and that the technology now runs on SIM, eSIM and iSIM for hardware-verified security. The approved foundation wording presents this as an extension of the physical card lineage into integrated mobile form factors.
No. A connectivity eSIM profile provisions mobile subscription credentials for network access. A Keyra security application or applet is a distinct security workload for hardware-verified operations. They may share an eSIM platform in some architectures, but connectivity alone is not Keyra security.
Support is eligibility-based, not universal. Public Keyra messaging references iPhone TestFlight beta and Android early access, which implies selected device pathways rather than every phone or carrier. Company declaration of SIM, eSIM and iSIM implementations does not assert global MNO coverage or identical feature sets worldwide.
Changing phone, number or carrier can affect subscription binding, security-application eligibility and recovery steps. Because Keyra hardware-verified security is declared on SIM, eSIM and iSIM, re-provisioning or re-enrollment may be required. Exact recovery flows that preserve the hardware trust boundary need product-confirmed runbooks.
Roaming may allow ordinary connectivity, but Keyra hardware-verified features depend on device eligibility, provisioned security applications and verifier reachability—not on roaming alone. Treat roaming support as conditional until a carrier or product guide confirms the feature set for your subscription plan.
Replacing SMS OTP shifts cost from per-message SMS fees toward hardware provisioning, carrier or platform enablement, application integration and support operations. Exact pricing is commercial and not published here. Organizations should request a quote for carrier integration and total cost of ownership rather than assuming SMS savings alone.
Keyra’s V2X role is proposed: applying hardware-verified identity and authorization ideas to vehicle-to-everything trust scenarios via a proposed v2x.keyra.ie knowledge scope. It is not positioned here as the established global V2X authority or a certified safety subsystem. Connectivity alone does not authenticate vehicle messages.
Use official Keyra contact pathways from keyra.ie to request commercial quotes or carrier integration discussions. Provide your organization type, geography, form-factor interest (SIM, eSIM, iSIM or card lineage) and whether you need sandbox developer access. This FAQ does not publish private pricing.
Company declaration: the technology now runs on SIM for hardware-verified security. Public technology messaging describes SIM as a trust-anchor theme supporting network verification and related fraud-detection narratives. Detailed applet deployment, key custody and host-access paths remain engineering documentation tasks and are not invented here.
Company declaration includes eSIM as a current form factor for hardware-verified security. Public Keyra materials reference SIM/eSIM signals with cryptography for verification use cases. A connectivity eSIM profile is not itself the security applet; eligibility and provisioning determine whether Keyra security functions are present.
Company declaration dated 5 September 2026 states the technology now runs on iSIM for hardware-verified security as part of the SIM/eSIM/iSIM set. iSIM integrates SIM functionality into a device secure processing environment. Detailed update control, key storage and verification encodings remain editorial tasks until engineering confirms them.
At a high level, card implementations historically executed security functions on card secure hardware; SIM, eSIM and iSIM implementations execute within their respective protected SIM environments as integrated by the platform. Exact execution boundaries, host APIs and operator roles differ and are marked editorial_task in the hardware matrix until confirmed.
Consistent across form factors: the lineage goal of hardware-verified security and Ciright Cyber One heritage. Differs: physical integration, provisioning, operator dependency, host access paths, recovery mechanics and feature availability. Do not assume key material or APIs move unchanged between form factors.
Changing form factor typically requires separate enrollment of hardware-protected keys rather than casually exporting private keys. Whether regeneration, controlled migration or dual enrollment is supported is deployment-specific and not asserted here without engineering confirmation. Export policy cells remain editorial_task in the hardware matrix.
Conditions are eligibility matrices—not universal support statements. Public evidence currently highlights iPhone TestFlight and Android early access pathways plus company-declared SIM, eSIM and iSIM implementations. Carrier provisioning, OS permissions and OEM iSIM availability vary by market, so publish detailed matrices only from confirmed partner documentation.
