T-Mobile has once again raised the bar for 5G speeds, reaching record-breaking download speeds in recent network tests. The wireless carrier hit 4.3 Gbps on a Samsung Galaxy S25 and an even more impressive 6.3 Gbps using a test device powered by Qualcomm’s newest X85 5G modem.
To put that into perspective—at these speeds, you could stream every Super Bowl ever played in 8K resolution, all at the same time.
These speeds were achieved using T-Mobile’s 5G Standalone (5G SA) network, leveraging a technology called 6-Carrier Aggregation, which combines multiple 5G signals for a faster, more stable connection. The tests were conducted in real-world conditions, meaning this isn’t just a theoretical breakthrough—it’s a glimpse into what the future of mobile connectivity could look like.
Why This Matters
For everyday users, advancements like this mean faster downloads, lag-free streaming, and an overall better mobile experience. As more devices and applications demand high-speed data—think augmented reality, cloud gaming, and ultra-HD video streaming—network improvements like these will be crucial.
T-Mobile’s achievement is the result of a collaboration with Nokia and Qualcomm, both of whom are key players in pushing 5G technology forward. Nokia contributed its Massive MIMO radios and advanced beamforming, while Qualcomm’s new X85 5G Modem-RF system helped unlock the next level of speed.
