Mobile Network Operators that have shut down their 3G networks stand to lose a considerable amount of their inbound roaming revenues if a roaming subscriber is unable to connect to voice and data services. This results in significant lost roaming revenues for visited operators and less roaming competition leading to higher roaming rates and ultimately dissatisfied subscribers.

Evolved Mobility has resolved this connectivity issue by supporting both inbound and outbound roamers.

Evolved Mobility for Inbound allows visited operators that have retired their 3G networks to support roaming subscribers entering their network from home networks that do not support VoLTE roaming.

Evolved Mobility for Outbound allows home operators that have retired 3G to support their subscribers as they roam into visited networks that do not support VoLTE roaming.
