Sri Lanka has had 3 successive years of economic shocks – the Easter Sunday attacks in April 2019, nearly exactly a year later the onset of the Covid-19 pandemic, and then a year after that the outbreak of the deadly third wave of Covid-19. It is not surprising that the economic impacts on households and firms have been sharp. While there is no ‘one stop shop’ piece of information on the impacts – a survey or research report – there are plenty of reports that capture/analyze different aspects of it, everything from the CBSL Annual Report of 2019 and 2020, IPS State of the Economy 2020, the CCC-USAID survey on trade impacts, and the IFC survey on employment impacts. Yet, I am yet to see any analysis that used telco data to get a sense of the impacts – not necessarily to quantify the impacts, but rather to give us a clue/hint/additional perspective of the impacts.
While checking the Telecommunications Regulatory Commission (TRC) public releases for a different piece of work, I came across their monthly statistical updates providing key industry numbers. I became curious about a few data points and whether they could provide a different dimension/additional corroboration of the economic impacts of the multi-year economic downturn Sri Lanka has now been in.
Take for instance the mobile subscriber numbers. Between December 2009 and March 2019, the number of mobile subscribers (essentially, SIMs) increased from 11.1 Mn to 32.6 Mn – a near 3x increase in just over 9 years. It went from 69 mobile connections per 100 people to 150 per 100 people, with many folks having dual SIM phones, and also using multiple pre-paid SIMs – common dynamic SIM usage behaviour seen in developing markets. Yet, by December that year, mobile subscriptions had grown only very modestly to 32.89 Mn. How do we know it was modest? Well, in the period referenced earlier (111 months, between Dec 2009-March 2019), an average of 193,700 new mobiles subscriptions were added every month. But in the months immediately after the Easter Sunday attacks, between April to December 2019, only 32,200 new subscriptions were added every month. So, we see a structural break after April 2019.
By end March 2020 and the onset of the pandemic and the first harsh curfew, mobile subscribers stood at 31.9 Mn – more than 1 million fewer than just three months prior. This means that each month around 336,000 mobile subscribers were being shed – for the first time in recent history. Fast forward to where we are today. The latest data – for March 2021 – suggest total mobile subscribers are at 29.2 Mn. This means that in two years, Sri Lanka had a 3.4 Mn decline in mobile subscribers.
I am not a telco market expert, so I spoke to a few friends in the industry, in a couple of different operators, to get some interpretation. There could be several factors driving subscriber/SIM behavior. During a pandemic and lockdowns, pre-paid customers find it extremely difficult to access mobile top up services (‘reload’) – at local corner stores, communication shops, and operators’ own outlets. Familiarity and willingness to use online top up options is very low. Additionally, it often requires using a credit or debit card – which most pre-paid customers may not have. Many of those I spoke to acknowledged that the reduction in subscribers certainly does indicate that users that may have had multiple SIMs may have given these up as they are unable to top up several, and instead focussed on 1 or 2. Given the impact on the tourism sector, it could be that tourism sector informal players that maintained multiple devices with multiple connections, began to cut down. What I was unable to find out (yet) was 1) at what point does a subscriber get ‘removed’ from an operators database as being considered as a subscriber (I believe this varies by operator – some have 90 days, some have 120 days, etc) and 2) what the reporting basis for TRC is, since this data is compiled by the TRC based on the numbers that operators send to them.
Going beyond the national aggregates, I wanted to check for any regional disparities/geographical differences. This could give an indication of where the changes happened more sharply than others. The TRC’s monthly reports from a couple of years ago have started to report the ‘Provincial Distribution of Mobile Cellular Phones’ (typically the last page, in a SL map). Sense check: Although the title indicated ‘mobile cellular phones’ and not ‘mobile subscribers’, a bit of cross checking of the numbers showed that this indeed was the same as mobile subscribers.
So, what does the province-wise analysis reveal? In the two-year period between December 2018 and December 2020 (the latest available), the Eastern Province saw the sharpest percentage fall in mobile subscribers of 15.8%, and the Uva Province the smallest of 6%, from among the nine provinces. The Western Province saw a decline of 13.4% (60,416 each month), the Southern Province saw a decline of 12.8% (20,416 each month), the Northern Province saw a 13.7% decline (8,750 each month) and the central province a 9.9% decline (15,41 each month). It was interesting to see that, after the Western Province, the second monthly decline in absolute terms was from the Southern Province. This could possibly be due to the high dependence on the tourism sector there, and the deep impacts of the successive shocks during the two years.
I also thought of looking at how the average monthly decline stacked up against the total subscribers at the start of the period – a ratio, sort of a measure of ‘decline intensity’. Higher the ratio (closer to 1) stronger the intensity. This was sharpest in the Eastern Province at 0.66, followed by the Northern Province at 0.57, Western Province at 0.55, Southern Province at 0.53, and North Central Province at 0.48. The lowest ‘decline intensity’ was the Uva Province at 0.25.
Another set of numbers that I thought would be interesting to look at are the monthly traffic generation and termination data. In this, I thought of looking particularly at the international incoming and outgoing call duration data, as a possible proxy for Sri Lanka’s international business activity like trade, exports, and tourism. There is an implicit assumptions being made here – that the majority of household/personal/family and friends overseas calls is more likely to be on data/VoIP rather than voice, and its likely that the majority of voice calls still being made is by business. So, aside from the general steady reduction in international incoming and outgoing voice calls anyway (with the increasing use of data/VoIP – WhatsApp, Viber, Telegram, Skype, etc), there has been a sharper decline following the onset of the pandemic. Monthly outgoing international calls went from an average of 13-13.5 Million minutes during 2019 and early 2020, to sharply dropping to 10.8 Mn by June 2020, and 6.7 Mn by September 2020. This is explained not just by the likely drop in business activity, but probably more by the fact that with most firms deploying work-from-home (WFH) practices, employees did not have access to their office phones for international voice calls, and used their personal phones to call internationally using data services instead. Interestingly, international voice calls had picked back up to 7.2 Mn by March 2021, with firms shifting back to working in offices, and presumably the temporary recovery in business activity). (By the way, international incoming calls follow more or less a similar trend). The next few months would be interesting to see – with the third wave and impacts on business activity and work from home, how will the numbers change?
I think its important to look at these TRC numbers alongside some other numbers to see what it adds to the picture. Operator-specific data is hard to come by, and we only have Dialog Axiata releasing comprehensive data in annual reports and quarterly financials as they are listed on CSE (and some insights on Mobitel, because SLT is also listed). Dialog’s latest financials show that Average Revenue Per User (ARPU) has fallen from a high of LKR 390 in Q1 2019 to LKR 364 by Q1 2021.
Having said all this though, the ‘data usage’ numbers certainly suggest rising usage overall. Monthly broadband data usage (compiled by the Central Bank from four operators), which had been growing steadily from 60 Million Gigabytes in January 2019 to 90 million in February 2020, reached a peak of 120 million Gigabytes in April 2020 as Sri Lanka went into its first lockdown. Data usage since then has risen and fallen alongside Government imposition of lockdowns, to reach 150 million GB by December 2020. Year-on-year growth in broadband data usage stood at 80% by end 2020.
Dialog’s data usage per subscriber per month topped 8.2 GB in 1Q 2021, from 3.3 GB in the same period three years ago. And overall, revenue is up. Dialog registered a strong 12.3% YoY rise in revenue in Q1 2021 to LKR 32.85 bn. Mobitel’s revenues in Q1 2021 rose 8.1% YoY to LKR 11.6bn.
What we can’t tell from all these data usage numbers is any level of disaggregated by income/socio-economic group, by occupation type, and geographical location.
In summary, looking at the TRC data was interesting. I don’t know what major conclusions can be drawn from it. While the findings are not conjecture, they are not conclusive either. It just provided someone curious with an additional way of exploring the economic impacts of recent downturns. I will keep talking to folks in the telco sector to dissect this dat further, and understand the dynamics a bit more to see if more curious conclusion could be drawn. No doubt, the micro-data that telcos have would provide much richer insights, with all sorts of analytical ad research possibilities. I hope that the government and/or think tanks partner with them to conduct these; it could potentially inform policy making around Covid-19 relief, stimulus and recovery efforts.
