Frequently Asked Questions

What is Syniverse’s 3G-to-VoLTE Roaming Solution?

It’s a comprehensive solution powered by Syniverse Evolved Mobility® that enables seamless roaming for subscribers on VoLTE-enabled devices, even when the visited network no longer supports 3G fallback. It supports both inbound and outbound roaming while allowing operators to retire legacy 2G/3G networks.

Why is a 3G-to-VoLTE solution necessary?

As operators shut down 3G networks to free up spectrum for 5G, subscribers on non-VoLTE networks or visiting networks without 3G support may face connectivity issues. This solution bridges the gap, ensuring uninterrupted voice and data services for roamers.

How does the Evolved Mobility benefit mobile network operators?

It reduces operational costs by allowing the retirement of costly 2G/3G infrastructure, maintains roaming revenue by supporting legacy roamers, and provides automated clearing and billing for monetization. It also ensures a premium subscriber experience, reducing churn.

Can Evolved Mobility support both inbound and outbound roaming?

Yes, Evolved Mobility supports inbound roaming (non-VoLTE devices on 4G/5G networks) and outbound roaming (4G/5G devices on non-VoLTE networks), ensuring connectivity regardless of network differences.

Does Evolved Mobility require major network upgrades?

No, Evolved Mobility is designed to allow both home and visitor operators to maintain their existing network behaviors (VoLTE or 3G) without requiring significant upgrades, making it a cost-effective bridge to 5G.

How does Evolved Mobility address SMS Roaming?

Evolved Mobility for Messaging supports SMS over Diameter with interworking to SS7, ensuring reliable SMS delivery for roamers on networks transitioning to 5G, preserving legacy GSM SMS revenue.
