With 3G network sunsets on the horizon, Syniverse is prepared to help you navigate this migration.

Plans by operators to retire legacy 2G and 3G networks are designed to reduce costs and accommodate increasing 4G and 5G bandwidth demands by reallocating spectrum. But these network shutdowns can create significant gaps when servicing inbound roamers, leading to lost revenues and a weakened position to negotiate outbound roaming rates.

Syniverse’s VoLTE roaming solution, Evolved Mobility, allows operators retiring their legacy networks the ability to serve inbound roamers with Voice over LTE (“VoLTE”) enabled devices from roaming partners who have not yet launched VoLTE on their network by allowing them the continued use of circuit switch fall back (CSFB) to successfully connect to voice and data services.

Evolved Mobility helps maintain inbound roaming revenues, strong partnerships, and happy mobile subscribers while supporting transitions to future technologies.

Time Is Ticking
3G is quickly heading the way of cassette tapes and Blockbuster video. While it played an important role during its heyday, it has since been superseded by more capable technologies like 5G -Light Reading
Opportunities for Efficiency
With the smartphone revolution, and the rapid growth in wireless data services, operators worldwide are exploring opportunities to reduce costs, or to reuse 2G/3G spectrum for the more cost efficient 4G and 5G technologies -GSMA
The Process Has Begun
GSMA Intelligence data shows that, from now to 2025, more than 55 2G and 3G networks will be closed, allowing operators to plan for 4G and 5G. -GSMA
Recover and maintain lost revenues from inbound roamers

If a roaming subscriber connects to a visited network that also no longer supports 3G, the subscriber then must have a VoLTE-enabled device, and their home network must also support VoLTE, in order for them to make a voice call and subsequently use data over that device while roaming.

A VoLTE roaming solution like Evolved Mobility allows 4G- and 5G-only operators to support 3G fallback for voice calls so that these calls could be made via VoLTE. This allows users on non-VoLTE networks to seamlessly make VoLTE-powered calls.

Seamlessly accept 4G connections across numerous networks

Evolved Mobility allows visited operators to effortlessly accept 4G connections across numerous networks and is intended to give non-VoLTE network operators a way to roam without either side having to make major equipment upgrades as we get closer to major carriers' 3G shutdown dates. Now, preferred networks can offer voice and data services without the use of VoLTE, giving roamers seamless connections to both voice and data and resulting in a mutually beneficial outcome for both roaming subscribers and mobile network operators.

Building a positive customer experience with roamers from non-VoLTE-supported home operators

Without the ability to connect to non-VoLTE-enabled operators in the wake of 3G sunsets, 4G- and 5G-only operators stand to lose a considerable amount of their roaming partnership business.

If a roaming subscriber is unable to connect voice services to a visited operator’s network, then they are also unable to connect to data services. This results in significant lost roaming revenues for visited operators, less roaming competition leading to higher roaming rates and ultimately dissatisfied business customers.
