methodology: "Market Audit methodology 1.1.0: public-source synthesis with attributable automated evidence, methodological and editorial checks. Evidence checked through 10 September 2026; source reference periods remain separate. Methods and calculation notes accompany the audit."
keyFindings:
- January–July 2026 data traffic increased substantially while fixed and mobile broadband subscription counts were nearly unchanged.
- Both compared groups reported higher H1 earnings; SLT’s Q2 operating expenses grew faster than revenue.
- Selected broadband offers create different recurring expenditure and initial cash requirements against one gross-wage benchmark.
- The household survey shows material urban, rural and estate differences in internet use and computer ownership.
limitations: Selected offers and company scopes do not establish national affordability, market shares or a sector revenue total. Historical survey periods, provisional statistics, company reporting and illustrative exposures retain their stated definitions. Research extensions appear at the end.

Sri Lanka’s telecommunications market is carrying more data through a largely stable broadband subscription base. The January–July 2026 regulator comparison shows substantial traffic growth, while company disclosures show rising half-year earnings and a less favourable Q2 cost comparison at SLT. For households, the economics of access include connection payments, recurring rentals and suitable devices. These conditions place capacity utilisation, service quality and affordable participation at the centre of the industry’s next stage.
## E0. Market boundary and observation periods
This audit covers licensed fixed, mobile, satellite, data and internet connectivity supplied to households and businesses in Sri Lanka. Wholesale capacity, international links and shared infrastructure are inputs; their value is not added again to retail spending. Device sales, television programming and standalone applications sit outside the market boundary. Integrated-group accounts are used at their reported scope.
This market review does not assess alleged scam operations or payment losses. The fraud-specific use of caller-number and subscriber-identity provisions is examined in [Telecom-Enabled Fraud in Sri Lanka: 2026 Evidence Review](/works/telecom-enabled-fraud-sri-lanka-2026/).
The classification anchors are ISIC Rev. 4 [6110, wired](https://unstats.un.org/unsd/classifications/Econ/Detail/EN/27/6110), [6120, wireless](https://unstats.un.org/unsd/classifications/Econ/Detail/EN/27/6120), [6130, satellite](https://unstats.un.org/unsd/classifications/Econ/Detail/EN/27/6130) and [6190, other telecommunications](https://unstats.un.org/unsd/classifications/Econ/Detail/EN/27/6190), restricted here to the stated connectivity activities.
*Evidence checked through 10 September 2026 under methodology 1.1.0. Historical welfare, wages and household-use surveys provide the baseline; operator accounts cover January–June 2026; monthly connection/traffic endpoints are January and July. May–July policy, August inflation and September offers have partly overlapping or subsequent periods. Household and individual observations are distinct from integrated-company outcomes.*
## E1. The connection base
Sri Lanka's growth in data traffic substantially exceeded growth in broadband connection counts between January and July 2026. TRCSL's provisional monthly sheets show:
| Subscriptions | January 2026 | July 2026 | Change |
| --- | ---: | ---: | ---: |
| Fixed access | 2,724,251 | 2,712,572 | −0.43% |
| Cellular mobile | 29,649,146 | 29,530,304 | −0.40% |
| Fixed broadband | 2,024,513 | 2,024,699 | +0.01% |
| Mobile broadband, 3G/4G/5G | 21,991,606 | 21,994,161 | +0.01% |
| Satellite broadband | 5,461 | 8,952 | +63.93% |
Categories overlap; subscriptions count connections rather than unique people. Sources: [TRCSL, January 2026](https://www.trc.gov.lk/content/files/statistics/2026/January%202026%20updated.pdf), [July 2026](https://www.trc.gov.lk/content/files/July%202026.pdf), statistical-overview panels.
Comparing the two monthly usage totals, reported mobile data traffic increased from **251,445 to 368,978 TB**, or **46.7%**; fixed traffic increased from **137,218 to 153,031 TB**, or **11.5%**. Both months contain 31 days. This is an endpoint comparison, without seasonal adjustment. The combination of nearly unchanged broadband counts and higher traffic places network capacity and utilisation at the centre of the market's development: operators must carry substantially more data without a proportionate expansion in connections. Satellite recorded rapid percentage growth from a small base, adding 3,491 subscriptions. [TRCSL monthly usage panels](https://www.trc.gov.lk/content/files/July%202026.pdf)
## E2. Macroeconomic conditions and affordability
### Real income recovery and renewed price increases
Sri Lanka’s economy grew **5.0% in 2025**. CBSL reports public-sector wages rising **14.9% in nominal terms and 14.7% in real terms** that year. This establishes an improvement in that group’s purchasing power during 2025, rather than recovery for every household or restoration of pre-crisis living standards. The private-sector statutory monthly minimum reached **LKR 30,000 in January 2026**. [CBSL, Annual Economic Review 2025, Chapter 1][aer]
The preceding welfare loss was substantial. The World Bank’s April 2025 assessment estimated poverty at **24.5% in 2024**, compared with **11.3% in 2019**, using USD 3.65 per person per day in **2017 PPP**. Food prices more than doubled between 2021 and 2024. These historical observations locate the subsequent recovery against a much higher cost of essentials. [World Bank, Staying on Track, pp. 26–29][wb]
The CCPI increased from **195.8 in December 2025 to 208.8 in August 2026**: a **6.64%** cumulative price increase, equivalent to **6.23% less purchasing power** for unchanged nominal income. August headline inflation was **8.0% year on year**, but the monthly increase was **0.28%**; CBSL attributed the rise in annual inflation principally to a food-price base effect. The index covers the overall urban Colombo consumer basket, including communication. [CBSL, August 2026 inflation release, pp. 1–2][cpi]
### Recurring expenditure and the initial financing requirement
The comparison below selects the four volume-based, anytime postpaid Home Wi-Fi offers on Dialog’s page on **10 September 2026**. Speed-limited unlimited and application-specific offers are outside this selection. The benchmark is **one worker’s LKR 30,000 gross monthly statutory wage**; a home connection may serve several people and be financed by multiple earners. [Dialog, advertised packages][tariff]; [CBSL, wage benchmark][aer]
| Allowance | Monthly charge, tax inclusive | Monthly wage share | Connection + one month | Connection + 12 months | First-year expenditure / annual gross wage |
|---|---:|---:|---:|---:|---:|
| 65 GB | LKR 1,593 | 5.31% | LKR 8,583 | LKR 26,106 | 7.25% |
| 100 GB | LKR 2,334 | 7.78% | LKR 9,324 | LKR 34,998 | 9.72% |
| 140 GB | LKR 3,075 | 10.25% | LKR 10,065 | LKR 43,890 | 12.19% |
| 175 GB | LKR 3,693 | 12.31% | LKR 10,683 | LKR 51,306 | 14.25% |
*Illustrative expenditure at unchanged advertised prices, using the LKR 6,990 online connection offer. Annual gross wage: LKR 360,000. Totals include only that connection price and the stated subscriptions; equipment outside the offer, refundable advances, electricity and additional usage are excluded. Connection plus one month measures first-month expenditure, rather than cash necessarily payable at activation. Totals are not verified checkout amounts or disposable-income ratios.*
For 65 GB, the first-year monthly equivalent is **LKR 2,175.50**. The connection-plus-one-month amount absorbs **28.61%** of the wage benchmark, compared with the recurring **5.31%**. The LKR 6,990 connection charge itself creates a potential liquidity constraint; an applicable refundable rental advance would increase initial cash requirements without adding to expenditure. [Calculations from Dialog’s advertised charges][buy]
Postpaid charges are invoiced at month-end. Dialog’s general broadband terms specify a **24-month commitment unless the registration form states otherwise**, customer purchase of equipment subject to discounts, and the right to collect one month’s rental in advance, settled against dues or refunded at termination. Offer-specific registration determines the applicable equipment price and commitment. [Dialog, broadband terms, clauses 1, 3 and 6, including 6.xiv and 6.xxi][terms]
### Customer expenditure includes substantial billing additions
Dialog’s guide reports effective additions of **23.50% for data** and **42.02% for domestic voice and specified value-added services**, including recovery in lieu of the Social Security Contribution Levy (SSCL). A **LKR 1,000 tax-inclusive budget** therefore corresponds to **LKR 809.72** or **LKR 704.13**, respectively, before these additions. These are effective billing additions rather than single statutory tax rates. The distinction separates money paid by customers from the underlying service charge; package-to-wage comparisons above use the advertised final rental. [Dialog, tax guide][tax]
### Financing and energy changes have different transmission periods
CBSL increased its policy rate by **100 basis points to 8.75% on 26 May 2026**, retaining that rate in July. PUCSL’s **18%** increase for categories including General Purpose 2 and 3 took effect on **11 May**. These changes overlapped only part of H1; borrowing resets and facilities’ billing categories determine their timing and exposure. [CBSL, May decision][may]; [July decision][july]; [PUCSL, May announcement][pucsl]
CBSL’s July review recorded monthly current-account deficits from April as fuel-import expenditure increased and tourism earnings weakened, despite strong remittances. Imported energy therefore raises both domestic operating costs and demand for foreign currency. For telecommunications procurement, pressure on foreign-currency availability can affect overseas supplier payments, while depreciation increases the rupee cost of unhedged equipment purchases. [CBSL, July review][july]
| Illustrative sensitivity—not measured operator exposure | Assumption | Calculated change |
|---|---|---:|
| Historical equipment procurement | USD 10m at year-end rates of LKR 292.58/USD in 2024 and 309.99 in 2025 | LKR 174.1m more; +5.95% |
| Annual interest | LKR 10bn floating-rate debt; full 1-percentage-point repricing | LKR 100m more annually |
| Eligible electricity expenditure | LKR 1m bill; uniform 18% proportional increase | LKR 180,000 more |
*Exchange-rate inputs: [CBSL, 2025 review, pp. 53–54][aer]. The electricity consumption-only offset is 15.25%, assuming fully proportional billing. Fixed and demand charges alter that relationship; cost absorption, sourcing changes and investment are other possible responses.*
## E3. Regulation and accountability
The **12 August 2025** broadband rules set these per-user field-test targets:
| Service | Download | Upload |
| --- | ---: | ---: |
| Mobile UMTS/LTE | >2 Mbps | >1 Mbps |
| Fixed wireless LTE | >4 Mbps | >1 Mbps |
| Fixed fibre | >4 Mbps | >2 Mbps |
These are regulatory test targets, not advertised package speeds or measured operator results. Tests use specified files and a TRCSL-designated remote server; technical limitations preventing achievement must be disclosed. For fixed wired and wireless services, the connection-supply targets are **70% of orders within seven days** and **95% within one calendar month**. Fault-repair targets exceed **70% within 24 hours**, **80% within 48 hours** and **90% within 96 hours**. [Broadband Quality of Service Standard Rules No. 01 of 2025, English pp. 25A, 28A–30A](https://www.trc.gov.lk/content/files/legislation/Broadband%20QOS%20rules(1).pdf)
Monthly and quarterly reports are due within 15 days of period-end; TRCSL audits submissions and publishes audited information. [Rules 10–14, p. 2A](https://www.trc.gov.lk/content/files/legislation/Broadband%20QOS%20rules(1).pdf)
## E4. Earnings and quarterly cost pressure
**Company-reported consolidated results, H1 2026**
EBITDA denotes earnings before interest, tax, depreciation and amortisation.
| Group measure | Dialog | SLT |
|---|---:|---:|
| Revenue | LKR 95.5bn; +9% | LKR 61.314bn; +11.1% |
| EBITDA | LKR 50.0bn; +23% | LKR 24.126bn; +13.7% |
| EBITDA margin | 52.3%, reported | 39.3%, calculated |
| Profit after tax | LKR 19.3bn; more than doubled | LKR 6.601bn; +54.4% |
*Sources: [Dialog, 14 August release][dialog]; [SLT, 17 August release][slt]. All growth figures are year on year. Consolidated scopes include activities beyond retail telecommunications. Margins are not an efficiency ranking without reconciling business mix and accounting treatment.*
SLT’s more recent quarter complicates the positive half-year picture:
| Year-on-year growth | H1 2026 | Q2 2026 |
|---|---:|---:|
| SLT group revenue | 11.1% | 11.7% |
| Group operating expenses, excluding depreciation and amortisation | 9.6% | 12.2% |
| Mobitel revenue | 12.9% | 16.0% |
| Mobitel operating expenses | 11.0% | 18.0% |
Operating expenses grew faster than revenue in Q2 at both levels. SLT’s quarterly EBITDA margin was approximately **39.19%**, compared with **39.47%** a year earlier, reconstructed from rounded growth rates: a decline of about **0.28 percentage points**. This indicates modest quarterly margin pressure. Management cited currency, fuel, utilities and network-related expenses; the figures do not isolate their individual contributions. [SLT company release][slt]
Dialog’s reported profit included foreign-exchange gains; excluding them, profit was **LKR 18.8bn**. Management also attributed earnings growth to lower net finance costs and operating improvements. Capital expenditure reached **LKR 18.5bn**, principally for 5G deployment. These disclosures identify financing and treasury effects alongside revenue and operating-cost changes. [Dialog company release][dialog]
## E5. Customers, devices and unequal participation
DCS surveyed 12,500 households in January–June 2025, covering persons aged 5–69.
| Residential sector | Internet use, persons aged 5–69 | Households with a desktop or laptop |
| --- | ---: | ---: |
| Sri Lanka | 60.4% | 21.4% |
| Urban | 71.9% | 36.3% |
| Rural | 58.8% | 18.9% |
| Estate | 45.6% | 5.8%† |
*Internet use means at least once during the preceding twelve months, not daily connectivity. Household computer ownership excludes smartphones. † DCS flags this estimate for high sampling variability. Source: [DCS, Computer Literacy Statistics 2025, first six months, Tables 1 and 8, pp. 1 and 4](https://www.statistics.gov.lk/Resource/en/ComputerLiteracy/Bulletins/2025-FirstSixMonths.pdf).*
The urban–estate internet-use difference was **26.3 percentage points**. The accompanying computer-ownership disparity suggests that network expansion alone cannot equalise participation in activities requiring a computer. Suitable devices and payment capacity remain complementary requirements; the survey does not isolate their causal effects.
## E6. Delivery channels, suppliers and partners
The supply chain includes retail access and separately licensed international gateways. TRCSL's register lists **Sri Lanka Telecom and Dialog Broadband Networks** as fixed operators, and **Dialog Axiata, Mobitel and Hutchison Telecommunications Lanka** as mobile operators. Its gateway category includes Dialog, Mobitel, Hutchison and **TATA Communications Lanka**. The repeated names show how retail and upstream permissions overlap within firms; gateway licences do not represent additional retail mobile competitors. [TRCSL system-licence register, fixed/mobile/gateway tables, inspected 10 September 2026](https://www.trc.gov.lk/licensing/pages_e.php?id=13)
International service also depends on commercial partnerships. At its December 2025 5G launch, Dialog reported 5G roaming arrangements with **155 operators across 76 countries**. Such agreements extend the service sold by a domestic network into overseas connectivity for travellers; the partnership count describes commercial reach rather than the capacity of Sri Lanka's access network. [Dialog, 18 December 2025](https://dialog.lk/news/dialog-launches-sri-lankas-largest-5g-network-connecting-over-1.5-million-subscribers)
## E7. Competition and alternatives
The Dialog–Airtel transaction changed ownership and reporting boundaries. Dialog announced that Airtel Lanka ceased as a separate corporate entity on **30 August 2024**, with Dialog surviving the amalgamation and absorbing its operating results. The Airtel brand continued within that structure. A separately marketed brand therefore did not represent a separately owned network competitor. [Dialog amalgamation announcement, 30 August 2024](https://dialog.lk/news/dialog-axiata-completes-amalgamation-with-airtel-lanka)
The regulator's current register lists three mobile operators and two fixed operators. Together with the completed amalgamation, this supports a structural finding: mobile competition operates among fewer independent networks than a brand count would suggest, while the fixed and mobile businesses of the two integrated groups span alternative ways of supplying connectivity. [TRCSL licence register](https://www.trc.gov.lk/licensing/pages_e.php?id=13) For a customer choosing between mobile data and home broadband, the relevant competitive offer combines allowance, recurring charges, connection costs and service at the location. The fixed-broadband illustration in E2 shows why monthly headline prices alone omit part of that comparison.
## E8. Technology and transition
The December 2025 spectrum allocation concentrated the initial 5G awards in two operators:
| Award recipient | Frequency block | Bandwidth |
| --- | --- | ---: |
| Dialog Axiata | 3,400–3,500 MHz | 100 MHz |
| Sri Lanka Telecom Mobitel | 3,500–3,600 MHz | 100 MHz |
| Dialog Axiata | 27,200–27,400 MHz | 200 MHz |
Source: [TRCSL award notice, 19 December 2025](https://www.trc.gov.lk/newsdetails_e.php?nid=103). These are assigned spectrum blocks; bandwidth in different bands is not an interchangeable measure of geographical coverage.
Dialog's launch announcement the previous day described **over 220 live 5G sites**, positioning 3,500 MHz for wider-area mobile service and 27 GHz for high-capacity applications. It also announced a **USD 100 million investment plan over two years**. The plan is a company commitment, distinct from expenditure already incurred. [Dialog 5G launch, 18 December 2025](https://dialog.lk/news/dialog-launches-sri-lankas-largest-5g-network-connecting-over-1.5-million-subscribers)
Dialog's later H1 2026 results release reported **more than 1,000 live 5G sites**. Neither site count establishes population or geographical coverage, active 5G use or experienced service quality.

The strategic problem is consequently both technical and commercial. Additional radio capacity can accommodate higher traffic, but investment recovery depends on the services customers buy and the revenue earned from that capacity. E1's traffic growth alongside stable broadband counts gives this distinction practical significance: carrying more data and adding more subscriptions are different routes to network expansion.
## E9. Outlook and scenarios
The central commercial question is how traffic growth converts into revenue sufficient to finance delivery. Under a utilisation-led pathway, existing and new capacity carries additional paid usage, spreading network costs across a larger service volume. Under a margin-pressure pathway, data volumes increase faster than monetisation while energy, procurement and financing costs rise.
These are conditional interpretations without assigned probabilities. Their distinction turns on revenue earned per consistently defined service volume, expenditure per unit of delivery and measured service quality. Rising traffic alone establishes neither higher profitability nor deteriorating experience.
## E10. Opportunities, threats and critical success factors
The opportunity lies in serving greater data use and customers whose device and payment constraints shape the service they can buy. Network investment supports that opportunity when usable capacity reaches the locations and applications generating demand. Cost escalation creates a competing pressure on margins and customer prices; connection payments can constrain initial cash even when monthly rental is manageable.
| Analytical success factor | Basis in this audit | Observable indicator |
| --- | --- | --- |
| Reliable authorised delivery | Spectrum allocation and specific quality obligations | Throughput, installation time, faults and restoration at compatible test conditions |
| Sustainable customer value | Different recurring, connection and device requirements | Total service expenditure, retention and participation across customer groups |
| Investment matched to demand | Higher traffic alongside nearly stable broadband counts | Capacity utilisation, service revenue and consistently scoped operating costs |
| Inspectable performance | Different quarterly and half-year cost comparisons | Stable definitions, period-specific results and published quality measurements |
These are analytical propositions rather than measured weights or certifications of individual operators. Sustained divergence between added capacity, paid usage and delivered quality would weaken the investment case; stronger participation with manageable service expenditure would support it.
## E11. Assessment and future research directions
The evidence describes higher data usage and continued network investment within unequal conditions of access. The operator comparison demonstrates why demand growth and changes in costs need to be assessed together. The tariff example identifies separate expenditure and liquidity requirements, while the household survey documents differences in internet use and computer availability. Profitability, service capacity and household access therefore move through related but distinct economic channels.
*Future research directions — Matched tariffs, household income and service-quality records could clarify adoption across income groups and districts. Linking investment to usable coverage would establish who benefits. Facility energy exposure and debt-reset schedules could quantify cost shocks; comparable customer shares and environmental measures would support further competition and sustainability analysis. The present evidence supports neither a national revenue total, an operator ranking, a causal merger effect nor a quantified forecast.*

Affordability calculations use monthly rental M and advertised connection C: recurring ratio = M/30,000; connection-plus-month = C + M; first-year expenditure = C + 12M; annual ratio = (C + 12M)/360,000. Percentage outputs multiply these ratios by 100. The first-year measure assumes continued subscription and unchanged prices, not a 12-month contractual term.
Calculated expenditure ratios are rounded to two decimal places. The comparison table rounds EBITDA margins to one decimal place. Unrounded SLT margins: H1 39.348%; Q2 39.191% = 100 × 11,960/30,517; reconstructed prior Q2 39.474% = 100 × (11,960/1.109)/(30,517/1.117). Approximate change: −0.283 percentage points, subject to rounded growth inputs. The tariff transcription preserves selected price observations, not complete archived pages or verified transaction totals.
