Check out the developments in detail below:
1. Syniverse and Skylo Partner to Enable Two-Way Satellite SMS Messaging for Verizon
Syniverse, a global mobile communications company, and Skylo Technologies, a non-terrestrial network (NTN) communications specialist, have partnered to implement two-way SMS messaging over satellite networks for Verizon. The partnership extends satellite connectivity beyond emergency services, supporting native SMS messaging over satellite for Verizon customers, Syniverse said on Monday, April 28.
Sky launched emergency messaging and location sharing for Verizon customers in 2024, with SMS messaging over satellite now available on select Verizon devices.
This collaboration allows mobile network operators (MNOs) to offer satellite-based text messaging without the need to alter their existing infrastructure, hardware, or network architecture. The solution integrates Skylo's non-terrestrial network (NTN) technology with Syniverse's Evolved Mobility for Messaging platform, which facilitates interoperability between terrestrial and satellite networks. By leveraging the Diameter protocol—commonly used in traditional cellular networks—the platform ensures reliable, scalable, and secure messaging connectivity.
Skylo utilises licensed Mobile Satellite Service (MSS) spectrum within globally allocated frequency bands, allowing it to provide satellite coverage in remote and underserved regions. This approach not only avoids interference between satellite and cellular networks but also doesn't require MNOs to share their terrestrial spectrum assets.
"Whether you're atop a mountain, miles off the coast, or reeling from an earthquake, a satellite network offers peace of mind in a time of need — but only if you can access it," said Andrew Davies, Chief Executive Officer of Syniverse. "Evolved Mobility for Messaging helps mobile network operators overcome interoperability challenges when integrating with Non-Terrestrial Networks like Skylo."
Skylo's VP of Engineering and Operations, Jerome Baccelli, emphasised the broader implications for global connectivity. "Our collaboration with Syniverse makes it easy for mobile network operators to extend the same technology used for terrestrial SMS to satellite communications. Skylo's standards-based solutions go beyond the air interface to include the entire cellular ecosystem."

With advanced Non-Terrestrial Network (NTN) technology, based on the 3GPP Release 17 industry standards, devices can seamlessly switch between mobile and satellite networks. This ensures an uninterrupted connection from the same device without the need for large, traditional satellite dishes, Skylo explained.
"Skylo is excited to partner with KPN to launch satellite-based IoT services across the Netherlands, and around the world while opening parts of the globe once thought impossible to reach. This collaboration will empower KPN's customers in sectors like agriculture, energy, maritime, and transportation with enhanced connectivity, improving business efficiency, asset tracking, safety, and reliability," said Paul Hanton, Global VP for Carrier Partnerships at Skylo.
3. Viasat Demonstrates Direct-to-Device Satellite Communication in Brazil
Satellite communications company Viasat announced it has successfully demonstrated its direct-to-handset (D2H) mobile satellite communication in Brazil. This demonstration, witnessed by local partners, government and telecom operators, showcased two smartphones connecting directly via satellite without relying on terrestrial infrastructure. This technology, using 3GPP NTN standards, aims to address the limited mobile coverage in remote parts of Brazil.
Viasat said this signifies the start of a new age of connectivity in the country where only about 18 percent of the geographic area is covered by cellular networks, according to Anatel data published in September 2024.
The demonstration focused on two primary scenarios in which D2D technology was utilised: direct-to-handset communication and data transmission for internet-of-things (IoT) devices in the agricultural and transportation sectors, with plans for expansion into additional markets.
Leandro Gaunszer, General Manager, Viasat Brazil, said: "It shows that reliable primary satellite communications over smartphones and IoT applications are far more available, opening the door for a future where technology will help build the bridge to the unconnected and make it available to a wider range of individuals and companies, regardless of where they are located. Our extensive L-band coverage and alignment of satellite technologies with 3GPP standards provide a strong foundation for introducing this groundbreaking solution to the country."
Viasat noted a GSMA Intelligence study suggesting potential global D2D revenues could exceed USD 30 billion per year by 2035. The large areas of Brazil without terrestrial connectivity represent a significant opportunity for MNOs, OEMs, and solution providers.
Viasat said it plays a key role in advancing open architecture standards-based D2D connectivity as a founding member of the Mobile Satellite Services Association (MSSA), a nonprofit organisation that brings together a wide range of industry players to promote mobile satellite connectivity on a global scale. The company also collaborates with chipset manufacturers and other connectivity providers to help enable D2D technology to become widely available in the coming years.
