Protect roaming quality before customers notice

Measure roaming voice performance across technologies using active testing that checks connectivity, audio quality, delay, and voice-service behavior in live roaming scenarios.

• Measure ringing, answer success, and answer delay

• Measure voice quality for the calling and called party using MOS with the ITU-T P.863 POLQA reference method

• Measure audio delay for both ends of the call through clock-synchronized test nodes

• Verify IMS and VoLTE registration and successful VoLTE call completion

• Verify CSFB behavior in LTE networks where VoLTE is not available, including return to LTE after the call

Test roaming SMS services across 2G to 5G to confirm that messages are delivered correctly, on time, and with the expected content and sender information.

• Verify true message delivery success and delivery delay

• Validate message content and sender address

• Verify SMSC and delivery report indication

• Check successful IMS registration for SMS over IP 

• Validate welcome SMS reception when registering in the visited network

Test the full data-session journey so you can verify connectivity, throughput, latency, and service quality across roaming data scenarios.

• Verify each step in data session establishment, including Location Update, PDP Context, IP lease, DNS lookup, and web server access

• Measure download and upload speed in HTTP/HTTPS and FTP/FTPS

• Run tests such as ping and roundtrip delay

• Verify expected higher data speed, lower latency, and service level in 5G

• Verify additional 5G parameters such as support for dual connectivity in 5G/NR

Validate that roamers can connect to the visited network correctly across supported technologies and selection modes, from the moment they arrive.

• Verify Location Update, PS Attach, and CS Attach success and delay

• Capture signal strength during registration

• Check IMS registration success and delay for IMS networks

• Validate registration success for 2G, 3G, 4G, and 5G

• Confirm registration in both manual and automatic selection modes

Generate the active tests needed for GRQ KPI reporting and IREG functional validation, with support for key GSMA roaming standards.

• Use test scenarios and scheduling features to generate the required tests for GRQ KPI reporting

• View results in interactive dashboards

• View results through distributed reports

• Provide the active test component used for IREG functional testing

• Support IR.24, IR.25, IR.32, IR.35, IR.38, IR.50, and IR.60

Test whether subscribers are steered to preferred networks, detect anti-steering behavior, and compare roaming performance against local users and other roamers.

• Register in the PLMN as steered by the preferred PLMN list

• Capture OTA messages sent to the user for steering purposes

• Use test traces showing the number and delay of Location

• Compare roamer experience with local users and other roamers in the visited network

• Get intelligence on which networks inbound roamers are registering

Validate eSIM and multi-profile SIM behavior across registration, data, SMS, and profile-management scenarios, including location-based profile changes.

• Use eSIM array hardware with MFF2 format support to host and manage eSIMs for testing

• Test profile management procedures according to GSMA RSP specifications for OTA SMS

• Verify successful network registration for the selected profile in the selected network

• Verify data connectivity and speed across 2G, 3G, 4G, and 5G

• Verify successful sending and reception of SMS

User-friendly test execution, automated scheduling, and detailed result storage help streamline the testing process.

• Execute interactive tests and get results back in real time

• Schedule test batches for automated, recurring execution

• Use story testing to simulate physical access to a roaming mobile phone in any covered country

• Trigger actions and monitor the response in real time

• Store detailed test results to support issue identification and resolution

Use dashboards, reports, and alerts to review roaming performance and respond quickly when issues appear. 

• Use web-based interactive dashboards to analyze results

• Analyze results from different angles and aggregation levels

• Use graphical, tabular, and combined reports

• Schedule reports for automatic emailing

• Define alerts to trigger automatically when issues are detected

Tracing provides technical information from both the mobile network and the test system to support troubleshooting.

• Use Layer 3 and RRC signaling traces between user equipment and the base station

• Use NAS signaling traces between user equipment and the core network

• Use test system trace data for troubleshooting

• Access technical information from both the mobile network and the test system

• Support deeper analysis of roaming issues
