Dialog Axiata PLC, Sri Lanka’s #1 connectivity provider, in collaboration with Huawei and Samsung, has achieved a significant milestone in its 5G journey by demonstrating 6.2Gbps speeds on its 5G Standalone (5G SA) Ready network — the fastest ever recorded in Sri Lanka on a commercial smartphone, the Samsung Galaxy S25 Ultra. This demonstration highlights the transformative potential of 5.5G Ultra Advanced Technology, setting a new benchmark for mobile connectivity in Sri Lanka. The trial was enabled by industry-leading innovations such as Massive MIMO, 3CC Carrier Aggregation in the sub-6GHz spectrum, and 1024QAM modulation, marking an important step in bringing next-generation mobile connectivity closer to reality. 

As the first and only network in Sri Lanka with a 5G SA Ready network, this breakthrough was achieved using a 5G public outdoor trial network with extensive optimisations to enhance performance. This milestone reflects Dialog’s ongoing commitment to advancing connectivity and unlocking the potential of 5G for consumers and businesses.

Huawei’s expertise and network solutions played a key role in enabling this achievement. Additionally, Samsung contributed by providing the required features on the Samsung Galaxy S25 Ultra, ensuring seamless testing and demonstration of 5.5G Ultra Advanced capabilities.

“Achieving 6.2Gbps on our 5G SA Ready network is an exciting step forward in our journey to enhance connectivity in Sri Lanka. This milestone demonstrates the potential of 5G to transform digital experiences. We remain committed to working together to unlock new opportunities for our customers,” said Dialog Axiata PLC Chief Technology Officer Ranga Kariyawasam.

Our latest innovations in Massive MIMO and Carrier Aggregation will help deliver unparalleled network performance and open new opportunities for Sri Lanka’s digital economy.”

“We are incredibly proud to showcase the groundbreaking 5G speeds achieved with our latest Galaxy S25 Ultra along with Dialog 5G. This device, with its advanced 5G capabilities, is a testament to Samsung’s dedication to providing future-ready devices that empower our customers in an increasingly connected world,” said Samsung Sri Lanka and Maldives Managing Director SangHwa Song.

Since becoming the first telecommunications provider in South Asia to demonstrate 5G capabilities in 2018, Dialog has continuously expanded its 5G innovation through the widest 5G trial network in Sri Lanka and several industry-firsts, including the first-ever 5G Standalone trial, first mmWave 5G trial in south Asia and the first Voice over 5G (VoNR) service trial in the country.

Beyond Sri Lanka, Dialog’s 5G connectivity extends to over 50 destinations through partnerships with more than 100 operators worldwide, offering seamless 5G experiences to roaming customers. Additionally, Dialog supports the widest range of 5G-ready devices, ensuring more customers can access the benefits of ultra-fast speeds and low-latency connectivity.
