Most of these products are supported by the SonimWare™ platform and enterprise services. In 2025, all of our new products that launched with tier-one carriers in the United States included a certification associated with carrier first responder initiatives, including FirstNet Ready, FirstNet Trusted, Verizon Frontline Certified, and T-Mobile certified for T-Priority. In the first half of 2025 we also announced the upcoming launch and availability of the XP Pro Thermal 5G smartphone for Europe which includes an SDK-enabled Sonim IRIS software for custom application development and an integrated thermal camera by FLIR® that benefits a number of vertical trades such as electricians, plumbers, public safety, construction, agriculture, amongst others.

Geographic market expansion continues with agreements and product availability through new distribution partners in Europe and South Africa, catering to carrier, reseller, and enterprise sales channels. Partners include Brodos, Modino, Ingram Micro, and Cernotech, which bolster our presence in these regions. This strategic alignment supports our commitment to offering reliable solutions and expanding our customer base.
