What device certifications does Teleki Blanka support for global IoT deployments?

Our eUICC platform is certified to GSMA SAS-UP (SGP.22 v3.0), launched in Q2 2023, and ships with native eSIM integration on Apple, Samsung, and Google flagship devices. Any eUICC-compliant modem, router, or telemetry module can be activated over-the-air from the Teleki Blanka console.

Can I provision and manage thousands of SIMs through an API?

Yes. The Teleki Blanka REST API supports bulk provisioning, real-time network switching triggers, per-device usage policies, and webhook events for billing and signal events. Customers routinely manage fleets of 10,000+ devices programmatically.

What SLAs and uptime guarantees come with business plans?

Enterprise contracts include a 99.95% network uptime SLA, 24/7 multilingual support in 14 languages with a median first-response time of 1m 47s, and ISO 27001 certified data handling audited annually by Deloitte. Our rolling 12-month actual uptime through December 2025 was 99.987%.

Do you support maritime and aviation use cases with specific carrier profiles?

Yes. Maritime customers receive optimized profiles for coastal and offshore coverage with session-persistent data, and aviation crew plans include in-flight network routing across 27 partner operators. Both verticals include dedicated account management and custom APNs on request.
