VisionROAM is a powerful inbound and outbound roamer monitoring tool featuring interactive and static dashboards that can be used by both technical and non-technical teams. It monitors individual roamers as well as roaming partnerships,
your market share and global roaming quality (GRQ).

  • CEM feature with multiple KPIs/KQIs : a dashboard including distinct counts, count of unique roamers for each services, history, distributions, failure types, steering of roaming (SoR), best/worst roaming partners and more.
  • Interactive dashboards : Customizable and dynamic web-based layouts with various metrics, including maps with distributions per country, tables, charts and graphs.
  • Marketing : Assess and improve your roaming partnerships, and detect which countries are the most profitable for marketing campaigns.

Full inbound/outbound roamer insights

VisionROAM monitors all inbound and outbound roamers. By predicting congestion caused by known roaming problems, it increases roaming revenue and saves time when it comes to investigating real network issues. Thanks to its interactive dashboards, it enables users to drill down to any fault’s root cause in a few simple clicks. And for the most demanding troubleshooters, SecureQOS allows you to drill all the way down to the protocol’s packets.

Monitor market share and roaming partnerships

As well as monitoring roaming partnerships, VisionROAM monitors operators’ market shares for outbound roamers in real time. These metrics are displayed on a world map, allowing you to gain insight on a specific country with just a click. VisionROAM enables you to easily identify steering-of-roamers and benchmarks all your roaming partners.

Degradation evaluation

Sometimes, underachieving KPIs may be caused by a single roamer generating a lot of failures. From the moment an issue’s detected, it is critical to evaluate how that issue is impacting roamers, especially if it is affecting the quality of service offered. VisionROAM offers an Impacted IMSI feature that has been developed to easily display a list of IMSIs affected by specific KPI measurements.

VisionROAM includes many features which are constantly improved based on user feedback following the Agile Manifesto. Main features include :

  • Map roaming partners: Provides an overall view of activity between countries
  • CEM and GRQ monitoring
  • Roaming partner analysis for inbound roamers
  • Called/calling network, allowing you to focus on specific equipment
  • Failure trends graph and root causes (congestion, steering of roaming, etc.)



Expandium is a vendor-independent company that uses its own big data platform consisting of non-intrusive passive probes (eProbes) and high-performance servers enabling 24/7 real-time monitoring. The platform is monitored by the Expand Management System (EMS) platform and VisionROAM, like our other solutions for mobile network operators, has been designed to work flawlessly on 2G, 3G, LTE, VoLTE, VoIP and VoWifi networks.
