What it is...

Trusted VoLTE Testing Ecosystem

Mobileum’s Roaming Performance Intelligence, powered by SITE-on-the-Go Premium API Testing, allows telecom engineers to initiate network validation tests directly from mobile devices. This solution ensures reliable, real-time service verification without the constraints of traditional testing setups.

and why it matters...

Future-Proof Your Voice Services

Eliminate cumbersome manual setups and boost operational efficiency by remotely validating network performance in real-time. Roaming Performance Intelligence significantly reduces deployment times, lowers operational costs, and ensures optimal customer experiences through instant feedback and precise validation.

Industry Challenges

Addressing VoLTE Roaming Pitfalls That Impact QoS

1
  • Inconsistent call setup and dropped VoLTE calls lead to poor roaming experience and increased customer churn
2
  • Troubleshooting delays in multi-operator environments make issue resolution slow and inefficient
3
  • Lack of IMS interoperability and fallback validation affects voice continuity during roaming
4
  • Growing complexity with 5G readiness and VoNR transitions requires advanced automation and proactive testing
