Calling these record-breaking speeds “impressive” would be an understatement — we’re redefining what speed really means! Today, T-Mobile (NASDAQ: TMUS) announced a groundbreaking achievement, reaching record downlink speed using Nokia’s cutting edge 5G RAN equipment. The testing was conducted on both a commercial Samsung Galaxy S25 and a non-commercial mobile test device leveraging the newly announced Qualcomm X85 5G Modem-RF, all on America’s largest and fastest 5G network.

The Un-Carrier with Nokia and Qualcomm Push Downlink Speeds to 6.3 Gbps Using Standalone and Sub-6GHz Spectrum in its Latest Field Test
The first test used a commercially available Samsung Galaxy S25 with the Snapdragon® X80 5G Modem-RF System running test software, leveraging T-Mobile’s industry-leading 5G network to reach downlink speeds of 4.3 Gbps in real-world conditions. In a second test, offering a glimpse into the next evolution of 5G Advanced, T-Mobile pushed the boundaries even further by leveraging the brand-new Qualcomm X85 5G Modem-RF on a mobile test device, achieving peak speeds of 6.3 Gbps.
Both tests combined low-band and mid-band spectrum on the Un-carrier’s 5G Standalone (5G SA) production network, delivering blazing-fast performance. To put these mind-blowing speeds into perspective, you could stream every Super Bowl ever played in 8K resolution—simultaneously. Once again, the Un-carrier sets the standard in 5G innovation.
“With 6-Carrier Aggregation, we’re not just adding another feather to our cap—we’re accelerating the future of 5G Advanced,” said Ulf Ewaldsson, President of Technology, T-Mobile. “This milestone isn’t just about speed; it’s about building a network that delivers exactly what our customers need—unparalleled performance, reliability, and innovation.”
T-Mobile’s record-breaking speeds were achieved in real-world field conditions on our production network, demonstrating both reliability and practicality. By leveraging its unique mix of owned spectrum bands (2.5GHz, PCS, AWS and 600MHz), T-Mobile has delivered results that are not just impressive but grounded in real world conditions —laying the foundation for future innovation.
“This achievement in collaboration with our long-standing partners, T-Mobile and Qualcomm Technologies, reflects Nokia’s commitment to developing 5G Advanced solutions with a strong focus on the areas that matter the most to our customers,” said Tommi Uitto, President of Mobile Networks at Nokia. “By combining our Massive MIMO radios, advanced beamforming techniques, high-order Carrier Aggregation, and high-order modulation, we have demonstrated the key building blocks of premium 5G Advanced performance—now successfully validated in a live customer network.”
“We are excited to have played a pivotal role in this achievement, utilizing our Qualcomm X85 Modem-RF to push the boundaries of 5G Advanced downlink speeds,” said Durga Malladi, Senior Vice President and General Manager, Technology Planning and Edge Solutions at Qualcomm Technologies, Inc. “This collaboration with T-Mobile and Nokia highlights our commitment to driving innovation and setting new benchmarks in wireless performance.”
