Enabling uninterrupted roaming services during 2G/3G sunset

2G/3G sunset can impact CSPs business along with their subscribers

The decision of phasing out 2G and 3G represents a major business and technological upheaval that is already impacting CSPs business along with their subscribers around the world. While this sunset is promising, reducing network complexity and opening ground for new services, shutting down these legacy systems and their subsequent transition to new and advanced generations (4G/5G) will create significant challenges for CSPs roaming business both in terms of revenue loss as well as service outage for roaming subscribers.
2G/3G sunset can impact CSPs business along with their subscribers

No 2G/3G spectrum will lead to no CS call, only option is VoLTE roaming, but CSPs still have a long way to go

As operators sunset their 2G/3G networks, they can no longer offer circuit-switch (CS) fallback for voice and SMS to in-roamers. The only option to provide voice service is via VoLTE, which requires VoLTE roaming agreements. However, VoLTE agreements take time, and some home networks may even not be ready with VoLTE. This could mean potential revenue loss for an operator, as the home network will want to steer their subscribers to competitor networks to guarantee voice and SMS services. Mobileum’s RoamFlow solution helps operators overcome this issue by enabling VoLTE for In-Roamers without VoLTE Roaming Agreements in place.
  • Possibility to check tariff billing in roaming
  • Establishing VoLTE roaming agreements is complex and time consuming
    • Operators will have to exchange devices as well as SIM cards
    • Will have to perform testing of multiple devices and not 1 or 2
  • Several HPMN are not yet ready for VoLTE Roaming
    • 500+ MNOs and MVNOs don’t have VoLTE even for domestic subscribers
  • Lack of manpower and resources

Safeguard your inbound roaming revenue by accommodating inbound VoLTE roamers when you have no VoLTE roaming agreements

Network interworking functionality allows two or more networks to talk to each other, in order to deliver services across networks. Mobileum’s RoamFlow solution is an interworking product, to address the lack of VoLTE roaming agreements in mobile network operators.  

Mobileum’s RoamFlow solution can enable VoLTE for subscribers even when there is no VoLTE Roaming agreement in place by acting as a translator between VoLTE and legacy circuit-switched (CS) systems. Moreover, RoamFlow will work for any subscriber with a VoLTE capable device. As the number of 2G and 3G sunsets worldwide tends to increase, interworking functionalities such as the one offered by RoamFlow can help operators without a 2G or 3G network, to increase their inbound traffic and revenue, as well indirectly boost their negotiations capability for wholesale rates for outbound traffic.
