T-Mobile demonstrations using a commercial Samsung Galaxy S25 and a non-commercial mobile test device achieved a 6.3 Gbps “record-breaking” downlink speed in a recent trial.
The Galaxy S25 test featured Qualcomm’s Snapdragon X80 5G Modem-RF System running text software on T-Mobile’s 5G network. It reached a download speed of 4.3 Gbps in real-world conditions.
The second test featured Qualcomm’s X85 5G Modem-RF on a mobile test device. It reached what the announcement called a “record-breaking” speed of 6.3 Gbps.
The tests used on Nokia 5G radio access network (RAN) equipment and low-band and mid-band spectrum on T-Mobile’s 5G standalone (SA) production network. The spectrum, which is owned by the carrier, is in the 2.5GHz, PCS, AWS, and 600MHz bands.
“With 6-Carrier Aggregation, we’re not just adding another feather to our cap — we’re accelerating the future of 5G Advanced,” Ulf Ewaldsson, T-Mobile’s President of Technology, said in the announcement of the T-Mobile speed achievement.
“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.”
Last month, Ookla released a study showing the percentage of use of 5G networks compared to LTE by users with access to both. The study found that T-Mobile subscribers in rural Florida spend 83.58% of their usage on 5G and urban subscribers in Illinois spend 91.86% of their usage on 5G compared to LTE.
Ookla also reported earlier this year that T-Mobile led mobile providers in data speed across all technologies combined — and specifically for 5G — in the second half of 2024.
Ookla’s Speedtest Connectivitiy Report said it was the fastest mobile network at 222.63 Mbps. T-Mobile had the fastest median upload speed at 11.45 Mbps the lowest latency at 49 ms.
