Keeping an eye on the SS7 connectivity in the core network for both inbound and outbound roaming scenarios.

A software update in a network element may affect the connectivity to your roaming partners’ MSC/VLR, SGSN or HLR, resulting in routing problems. As a consequence service is down, ultimately leading to a drop in revenues.

Tests to investigate the cause of the problem in both inbound and outbound scenarios are needed to verify and improve any network service difficulties. This is often costly and time-consuming.


With Roaming Radar you can test the availability of MSCs/VLRs, HLRs and SGSNs first on the core network level. By checking for these problems initially, operational costs and time spent can be kept low.

Receive real-time alerts for connectivity problems over the SITE platform and get to the root of network problems with network messages (SS7/SIGTRAN), provided to you via SMS, e-mail or SNMP.

While ad-hoc tests, recommended as an extension to IREG testing, ensure that connectivity problems with (new) roaming partners are discovered before costly service tests have to be run, permanent monitoring can detect problems even in regions with fewer subscribers.


Save time and money to identify connectivity problems in the core network!

  • Identify issues before customers complain
  • Test routing anywhere, irrespective of the location
  • Test frequently with low complexity and operational costs
  • Receive real-time outage alarms very fast due to dense schedule
  • Perfect to correlate with E2E testing through SIGOS solutions
