Sri Lanka’s telecoms market has moved through a difficult period since the economic crisis of 2022, when operators had to deal with currency depreciation, higher energy costs, power shortages and weaker consumer spending. The market now appears to be stabilising, but growth is no longer coming from basic mobile adoption. Instead, the story is increasingly about consolidation, mobile broadband usage, spectrum, and the first phase of commercial 5G.
According to data from GSMA Intelligence, by late 2025, Sri Lanka had 30.3 million cellular mobile connections, equivalent to around 130% of the population. That high penetration reflects the familiar pattern of multiple SIM ownership rather than universal individual adoption. At the same time, the total number of connections fell slightly, down by 314,000 or 1.0% during 2025, suggesting a saturated market still shaped by economic pressures.
On the technology side, the market continues to shift towards higher-speed networks. Around 91.3% of all connections are now classified as “broadband”, meaning they operate on 3G, 4G, or 5G networks. However, this should be interpreted with caution: not all of these subscriptions actively use mobile data, as some plans remain limited to voice and SMS services.
The operator landscape has also become simpler. Dialog Axiata completed its acquisition of Airtel Lanka in 2024, reducing the mobile market to three main network operators: Dialog, SLT-Mobitel and Hutch. This consolidation gives Dialog greater scale and spectrum efficiency, but it also increases the importance of regulatory oversight to ensure competition remains healthy.
The most significant change came in December 2025, when TRCSL awarded 5G spectrum following Sri Lanka’s first spectrum auction. Dialog and SLT-Mobitel each received 100 MHz in the 3.5 GHz band, while Dialog also secured 200 MHz in the 27 GHz band for high-capacity 5G deployments. This formally moved Sri Lanka from years of trials and pre-commercial activity into the commercial 5G phase.
Dialog Axiata remains the clear market leader in Sri Lanka, with a subscriber base of over 19 million users, giving it an estimated market share of around 55–60% of mobile connections. The operator has consistently led on technology, being the first to introduce successive generations of mobile networks including commercial 5G services, and continues to expand its next-generation footprint through partnerships such as its 5G RAN deployment with Ericsson and is now leading the country’s transition to 5G, having launched commercial services with over 220 live sites initially serving more than 1.5 million users, and rapidly expanding to over 800 sites nationwide within months of launch. Dialog’s early 5G rollout is underpinned by a strong spectrum position, including holdings in both the 3.5 GHz mid-band for coverage and 27 GHz mmWave spectrum for high-capacity use cases, positioning it well for advanced consumer and enterprise applications . The operator has further strengthened its leadership through the acquisition of Airtel Lanka, enabling greater scale, spectrum efficiency, and network synergies in an increasingly consolidated market.
Hutch, the Sri Lankan operation of CK Hutchison Holdings, remains the smallest of the country’s three mobile network operators but continues to position itself as a value-focused challenger. Hutch serves around 3.6–3.8 million subscribers, giving it an estimated market share of 10–12%, and positioning it as the third-largest provider.
The operator gained scale following its 2018 acquisition and integration of Etisalat Lanka, creating a combined entity with an estimated market share of around 25–26% and establishing it as the third-largest provider, just behind SLT-Mobitel. Hutch has since focused on expanding 4G coverage, having initially launched LTE services in the Western Province in 2018 before extending its footprint across the country, particularly in densely populated areas, while maintaining a strong emphasis on competitively priced data offerings.
On the technology front, Hutch has demonstrated early 5G readiness, conducting its first live 5G trial in March 2021 at its One Galle Face experience centre after receiving a trial licence from the Telecommunications Regulatory Commission of Sri Lanka. The trial, carried out in partnership with ZTE, achieved peak speeds of around 1.8 Gbps alongside low latency performance and showcased use cases including cloud gaming, remote collaboration, and high-definition video streaming. Despite these early demonstrations, Hutch has yet to move to large-scale commercial 5G deployment, reflecting a more measured investment approach compared to larger rivals.
SLT-Mobitel, the mobile arm of Sri Lanka Telecom, has a legacy stretching back over 160 years, originating with the first telegraphic circuit between Galle and Colombo in 1858, and the country’s first international telegraph link to India.. Today, SLT-Mobitel serves an estimated 6–6.5 million subscribers, representing roughly 18–20% of the market, positioning it as the second-largest operator after Dialog.
The operator has expanded its pre-commercial 5G network to key cities including Colombo, Kandy, Anuradhapura, Galle, and Jaffna, offering both mobile broadband and fixed wireless access (FWA) services. In 2021, SLT Group CEO Lalith Seneviratne confirmed plans for a pre-commercial 5G launch using spectrum in the 3.5 GHz band allocated by the Telecommunications Regulatory Commission of Sri Lanka, initially targeting enterprise applications. Full commercial deployment is contingent on final spectrum licensing, with an estimated one-year rollout period once approvals are issued. SLT-Mobitel has earmarked around USD 100 million for 5G network deployment, in addition to approximately USD 15 million for spectrum acquisition.
Sri Lanka’s mobile market has evolved rapidly since the economic turbulence of 2022, moving from a period of consolidation and cautious investment to one of technological advancement and 5G deployment. Dialog Axiata, with its dominant 55–60% market share, continues to lead the market through aggressive 5G rollout, spectrum strength, and the integration of Airtel Lanka, securing its position at the forefront of innovation. SLT-Mobitel leverages its long-standing infrastructure legacy and strategic investment in pre-commercial 5G to maintain its role as the second-largest operator, targeting both urban and enterprise users. Meanwhile, Hutch has carved out a value-focused niche, expanding 4G coverage nationwide and demonstrating early 5G capability through trials in partnership with ZTE, positioning itself as a smaller but agile competitor.
With 5G networks now operational in key cities, and operators investing in LTE densification and spectrum refarming for wider coverage, Sri Lanka is entering a new phase of digital connectivity. While challenges such as device affordability, rural coverage, and ROI considerations remain, the combination of network upgrades, regulatory support, and market consolidation suggests that Sri Lanka is well on its way to becoming a mature, 5G-enabled mobile market, offering both consumers and enterprises faster, more reliable, and innovative mobile services.
Overall, Sri Lanka is entering a more mature phase of mobile market development. Subscriber growth is limited, the number of operators has reduced, and 5G is now moving from demonstrations to commercial service. The key questions are no longer whether Sri Lanka will launch 5G, but how quickly coverage will expand, how affordable 5G devices and tariffs will be, and whether operators can turn new spectrum into profitable consumer and enterprise services.
