Our valued customers
Roaming Opening Testing
2G and 3G networks are phased out leading to a high demand of VoLTE testing (IR.25) to assure that subscribers can still use voice services while being abroad. GSE covers all relevant IREG scenarios to support Roaming opening testing.
SEGRON’s roaming quality tests utilize the unique end-to-end Active Testing Platform using real smartphones and supporting 2G, 3G, LTE, CSFB, VoLTE, 5G and emergency services. Real mobile data traffic can be generated and tested at any location, anytime! Based on our SIM & eSIM support tests can be flexibly carried out using different customer profiles which allows to measure and improve QoS and QoE, detect service outages through real-time reporting and altering.
Live Network Monitoring
Our innovative testing approach enables live network testing and service verification for mobile voice and data services, including Voice over LTE (VoLTE), Voice over New Radio (VoNR) and OTT voice services.
Based on our comprehensive Access, Voice, Data & Messaging KPIs, you can ensure the correct functionality and integration of your most important services, while related radio interfaces can be analysed using the Layer3 radio analysis.
As we are using real end customer devices for our tests you will automatically get the information about the correct functionality on one side and the customer experience (QoE) on the other side
5G, Network Slicing & Latency
The introduction of 5G networks brings unprecedented benefits, including faster data speeds and lower latency. However, it also increases complexity. The intricate architecture of 5G, with its use of diverse frequency bands, advanced technologies like Massive MIMO, and complex network slicing, amplifies deployment and management challenges. The denser network infrastructure required for 5G further complicates maintenance and troubleshooting. Additionally, the integration of diverse technologies such as IoT and edge computing as well as multi-vendor based networks due to ORAN technology heightens the overall complexity. All that leads to an increased need for end-to-end and interoperability testing. SEGRON’s solutions are able to orchestrate automated testing via one a single platform covering all relevant 5G capabilities using real end customer devices. Based on our powerful Layer-3 tracing solution we can verify the correct parameter settings and messaging flow according to 3GPP standards, for both 5G NSA and SA (VoNR). Of course, also the verification of network slices, download speeds and low-latency scenarios (eMBB, URLLC & mMTC) is covered.
Global SIM Connectivity Testing
Car V2X (Vehicle-to-Everything) enhances road safety, reduces traffic congestion, and enables efficient communication between vehicles and infrastructure for smarter transportation.
The majority of this communication is handled via mobile networks hence cars are equipped with SIM cards placed in telematics control units (TCUs). As cars travel across borders connectivity is required globally and in consequence SIMs must provide seamless Roaming globally.
SEGRON’s Global Service Enabler is designed to test connectivity globally. It supports physical SIMs and eSIMs and provides access to hundreds of mobile networks worldwide. All locations are equipped with mobile devices that are capable to register in 2G, 3G, 4G and 5G networks end hence cover all technologies available today.
Predefined test templates cover voice, data and messaging scenarios along with true L3 trace information for troubleshooting.
Connected Car Testing
SEGRON’s innovative approach enables live network monitoring by integrating real telematics control units (TCUs) in our platform and use them for testing.
Automation of use cases such eSIM profile change, wake up SMSes and eCall are just few examples of what can be implemented
During test executing our platform is interacting with the connectivity platform of the car manufacturer to trigger events and collect results, all fully automated.
All test sites can be remotely controlled, and data can be collected, visualized and analyzed in real-time using the powerful User Interface, without the need for any technical expertise.
2G/3G Sunsetting
As mobile networks phase out 2G and 3G voice services, operators face a critical challenge: ensuring uninterrupted voice connectivity for both inbound and outbound roamers. In many markets, VoLTE roaming is becoming the only viable path for reliable voice service — making it essential to confirm that roaming agreements, network behavior, and service quality are ready before legacy fallback disappears.
SEGRON’s Global Service Enabler helps operators proactively assure VoLTE roaming performance across live networks using real, unrooted smartphones. It enables continuous validation of service quality, roaming availability, and customer experience across different destinations, subscriber profiles, and call scenarios.
By detecting issues early, operators can reduce churn, protect roaming revenue, and avoid service failures when 2G/3G networks are finally switched off.
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.
