Empower your eSIM Experience Assurance
Ensure your eSIM services work flawlessly, before your customers find out they don’t. Verify eSIM connectivity, activation and service performance quickly.
Ensure seamless activation, reliable provisioning & continuous service quality
Even small issues in the provisioning chain can lead to activation failures, poor customer experience, and – in a market where switching providers is easier than ever – an immediate risk of churn. For service providers, this is not just an operational challenge. It is a revenue and reputation issue.
SEGRON gives service providers the confidence that installation, activation, and ongoing connectivity work reliably – across every device, network, and partner environment. The requirements differ by segment, but the stakes are the same: Travel eSIM providers must verify that subscribers can enter a country, attach to the visited network, and immediately start using data services – without friction or manual intervention. Enterprise and embedded SIM environments add further complexity, requiring validation of Discovery Service and Entitlement Server flows to ensure profiles are delivered, activated, and transferred correctly across the full provisioning chain. MVNOs depend on correct IMS, IMSI, and APN provisioning for voice, messaging, and data services to function as expected from the moment a subscriber activates.
SEGRON’s ATF & GSE are purpose-built to address all of these scenarios. Using real smartphones in live networks worldwide, ATF & GSE provide automated end-to-end solutions that validate eSIM activation, monitor service quality continuously, and benchmark your user experience against competitors – giving you the visibility to act before your customers notice a problem.

Monitor MVNO configuration quality
Validate IMS, IMSI, APN, voice, SMS and data behavior to detect provisioning issues before customers are affected.
Ensure reliable eSIM provisioning flows
Monitor activation, Discovery Service and Entitlement Server scenarios to confirm that profiles are delivered and transferred correctly.
Benchmark Travel eSIM quality
Compare service performance against competing providers, making quality a measurable differentiator in the travel eSIM market.
Our valued customers
eSIM Service Validation
Enterprise and embedded SIM management requires verification beyond initial activation. SEGRON supports automated validation of activation processes, Discovery Service flows where profiles are delivered automatically at device power-on, and Entitlement Server scenarios for tariff or profile transfer between devices.
By validating these processes on real devices, operators gain visibility into whether provisioning works reliably across different device types and service configurations. This helps reduce operational risk, improve process transparency and ensure a stable customer experience across the full eSIM lifecycle.
MVNO Service Monitoring
For MVNOs, correct service provisioning is essential to maintain data connectivity, voice quality and messaging functionality. SEGRON verifies the correct IMSI allocation, APN settings, attach success, data session establishment, and voice and SMS behavior in live networks using real smartphones.
This enables continuous validation of wholesale configuration and faster detection of issues such as incorrect APN settings, delayed SMS delivery or fallback to legacy network behavior. As a result, MVNOs can improve SLA compliance, identify problems earlier and protect customer experience.
Travel eSIM Testing
Travel eSIM services must work immediately when subscribers arrive in a destination country. The installation and activation process therefore needs to be verified continuously to ensure that profile download, activation, network attach and the first data session are completed successfully.
Any loss of connectivity to the provisioning platform or failure in the activation flow can directly impact customer experience and revenue. Automated end-to-end verification with real smartphones helps providers detect issues early, trigger proactive alarms and avoid activation-related support cases.
In addition, benchmarking against competing travel eSIM offers helps providers understand how their quality performs in real market conditions. This makes service quality visible and supports differentiation in a highly competitive travel connectivity market.
