The recent move by major telecom operators to phase out their 3G networks to free up spectrum for 5G and cut operational expenses has sparked significant media attention. This shift has been described as a "crisis moment," raising global concerns among consumers.

For businesses and travelers using VoLTE-enabled devices on roaming networks that haven't yet adopted VoLTE, there’s a solution to ease connectivity challenges when visiting operators have decommissioned their 3G services.

3G to VoLTE Roaming Solutions

Many international operators are retiring their 2G and 3G networks out of necessity. Phasing out outdated circuit-switched networks like 3G allows them to allocate spectrum to meet the growing demands for 4G and 5G bandwidth, essential for mobile and IoT devices across various sectors.

For operators who haven’t yet integrated VoLTE roaming, a 3G to VoLTE roaming solution ensures that subscribers using VoLTE-enabled devices can connect seamlessly when traveling on networks that have shut down their 3G services. This approach enhances customer experience by preventing disruptions for travelers whose home networks lack VoLTE roaming support.
A robust 3G to VoLTE roaming product enables both the visited and home networks to continue operating under their preferred roaming protocols, catering to the needs of both operators and users. This includes supporting voice and SMS services, as well as clearing and settlement processes for a comprehensive solution.
