- Qualcomm Turbo Dual-SIM Dual-Active (DSDA) is set to make 5G devices with dual-SIM and dual-data features faster, more reliable and more powerful — helping to shape the 5G landscape and enhancing the mobile experience.
Dual SIM smartphones allow users to operate two different SIM cards on one device, simplifying the management of separate numbers or networks. Devices with dual-SIM capability can optimize two concurrent 5G data connections by enhancing RF spectrum flexibility and network deployments, even in congested networks.
Key benefits and market impact of DSDA technology
Our previous DSDA generation introduced the dual-data concept, enabling dual-SIM users to simultaneously utilize two data streams from different subscriptions without interruption. This improvement enhanced user experience in data-demanding applications such as:
- Video streaming
- Large file downloads
- Online gaming
- Over-the-top (OTT) voice and video calls
These advancements contributed to the global rollout of 5G.
The global dual SIM smartphone market was valued at approximately USD 51.37 billion in 2024 and is projected to reach USD 91.24 billion by 2033, growing at a CAGR of 7.29%.* And this growth is driven by:
- Increasing demand for data communication flexibility among professionals and in emerging markets.
- Wider availability of dual SIM features in smartphones.
Understanding Qualcomm Turbo DSDA technology
We're now boosting dual-data-driven performance with Qualcomm Turbo DSDA, an innovative 5G Stand Alone (SA) solution for multi-SIM users that is part of the Qualcomm X85 5G Modem-RF. Downlink throughput on a smartphone can increase up to 60% from the previous generation, driving an enhanced user experience across performance, efficiency and more seamless connectivity.
Qualcomm Turbo DSDA introduces significant enhancements:
- Increased spectrum aggregation flexibility: More optimized spectrum usage maintains stable and high-speed connections even when multiple devices are vying for bandwidth.
- More component carriers: In a world’s first, the number of 5G SA component carriers was doubled from 2CC (1CC + 1CC) to 4CC (3CC + 1CC), boosting dual-data streams for faster and more efficient data transfers.
- Efficient response to RF conditions: Dynamic bandwidth management addresses deteriorating RF conditions and network congestion, improving overall data performance.
- Improved user data rates: Expanding the use of network deployments can enhance data rates.
Real-world applications: Qualcomm Turbo DSDA in action
Qualcomm Turbo DSDA offers significant benefits for real-world scenarios. By enabling multi-SIM functionality with faster dual-data speeds, it delivers practical enhancements to everyday activities in surprising and practical ways:
- HD video streaming: Even in crowded areas where network congestion is common, you can maintain stable and high-speed connections when running data-demanding applications, such as streaming HD video. With seamless communication and improved data transfer, Qualcomm Turbo DSDA reduces the frustration of slow internet speeds.
- Large file downloads: While downloading a large file, including an HD map or photos, you can work on other tasks, such as emails, online gaming or participating in a video call. Dual-data streams utilizing more component carriers, resulting in higher throughput for faster and more efficient data transfers, improves both app performance and the overall user experience.
Empowering next-generation 5G devices
Qualcomm Turbo DSDA is set to make 5G devices with dual-SIM and dual-data features faster, more reliable and more powerful — helping to shape the 5G landscape and enhancing the mobile experience. As manufacturers advance 5G capabilities for next-generation applications in consumer electronics, entertainment and automotive industries, Qualcomm Turbo DSDA will play a leading role in driving innovation and improving connectivity, allowing devices to handle demanding tasks simultaneously.
