Samsung's upcoming flagship smartphone, the Galaxy S27 Ultra, is expected to receive a significant upgrade in wireless connectivity when it launches early next year. According to industry sources, the device will feature Qualcomm's new X105 5G modem, which debuted at MWC 2026.
The X105 modem is anticipated to be integrated into future Snapdragon 8 Elite Gen 6 processors, which Samsung traditionally uses in its ultra-flagship phones for select markets. This new communication chip focuses on the 5G Advanced standard while simultaneously laying the technical groundwork for sixth-generation networks.
Key advantages of the X105 include higher data transfer speeds and improved energy efficiency. Qualcomm reports substantial increases in peak throughput and reductions in radio module power consumption—a crucial factor for large smartphones handling heavy network loads.
The standout feature is direct satellite connectivity support. This enables communication with low-orbit satellites in areas lacking traditional cellular infrastructure, allowing for messaging, calls, and data transmission during emergencies, such as in remote regions or natural disasters.
Additionally, the X105 supports backup communication standards like NB-IoT, which can be used where regular network signals are weak, such as in elevators, underground parking, or buildings with dense structures. Built-in AI algorithms predict connection quality and ensure more stable network performance while on the move.
If confirmed, the Galaxy S27 Ultra would be among the first Samsung smartphones to implement satellite connectivity at the modem level rather than as a separate software feature. This could significantly enhance the device's autonomy in critical scenarios and bring mainstream smartphones closer to the full hybrid networks of the future.
