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.
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.
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.
MNOs should separate subscription management from security-application enablement, plan provisioning and eligibility carefully, and engage Keyra through official channels for integration discussions. Company declaration affirms SIM as a current hardware-verified form factor, while commercial coverage, roaming behavior and applet lifecycle remain partner-specific.
