Internet in Sri Lanka: the state of affairs


Sri Lanka is seeing a massive surge in computer usage and internet penetration, but are you using the right connection? Don’t fall for random promises of speed and cheap connectivity: here’s how things really are. Here’s the state of Sri Lankan internet.

First things first: the connection

Sri Lanka is connected to the internet mainly using connections made to two undersea cables: SEA-ME-WE-3 and SEA-ME-WE-4.

Both connections are owned by SLT, with other Internet Service Providers having access as well. SEA-ME-WE-3, or South-East Asia – Middle East – Western Europe 3, is an optical cable linking the three mentioned regions together. It was commissioned in 2000 and is administered by Singtel, which is something like Singapore’s SLT: government-owned. Likewise, SEA-ME-WE 4, set up as a compliment to SEA-ME-WE-3, provides much of the internet connectivity between South East Asia and Europe. 


Apart from this, Lanka Bell has access to the Fiber-Optic Link Around the Globe(FLAG), which was sent into active service somewhere in 1997. It connects the US, UK and Japan to quite a few places in between, and over time has grown a network of feeder links. It’s owned and operated by India’s Reliance Globalcom and is also used by Dialog and Etisalat.

The ISPs and service

Currently, we have a number of ISPs offering two types of connections to Sri Lankan users: Fixed Broadband and Mobile Broadband. Note that “Fixed” doesn’t necessarily mean wires trailing from the nearest telephone pole: stationary 4G routers are getting to be the norm now rather than the exception. In this regard, SLT, Lankabell and Dialog offer fixed broadband facilities while others offer mobile-only services: Dialog and SLT are the only ISPs that offer both mobile and fixed broadband connections.

All the ISPs offer packages at capped data limits, when exceeded, reduces the user’s internet speed to 64kbps dial up speeds. The only exception is Lanka Bell, where they offer unlimited, fixed 4G connections.

Currently fixed line bandwidth ranges from 512Kbps to 16Mbps across various ISPs. Only SLT offers 512Kbps connections and soon, as the TRCSL tell us, 512kbps connections would cease to be categorized as broadband: they’re planning to revise the definition for broadband to make i so that a connection should have a minimum 1mbps bandwidth for it to be considered. Anything less would soon be categorized as narrowband.

Each ISP is, by law, required to provide a major percentage of what they promise on paper. Remember that speed in the telecommunications industry is measure in bits per second, whereas we’re used to downloading in bytes per second. This difference is crucial. As one byte = eight bits, an 8Mbps line, therefore, is capable of a theoretical maximum of one megabyte per second and no more.

Considering the rest of the world, we’re somewhere in the middle of the pack. Our internet is nowhere near as expensive as, say, Brazil. Nevertheless, largely due to the cost per MB of connecting to the world, our connections are heavily data-capped.

How we got here

Sri Lanka Telecom (SLT) was the first to connect to the internet in Sri Lanka – they obtained connections to the internet in 1995. Lanka Internet started providing internet to consumers in the mid 90s using a Satellite link. At the time most household connections were on 14.4 Kbps dial up connections used mostly by enthusiasts. You could get 10KBps on your downloads on a really good day.

Choosing The Right One

Choosing the correct package and an ISP that suits you require some careful thinking depending on your needs.

If you don’t have a land line connection or you are moving around regularly, a 3G HSPA dongle is considered the norm. Although connections have been fairly fast since the beginning, these connections cost more per GB, need some heavy data budgeting to be used effectively and there are reports of bad Quality of Service (QoS) related to HSPA connections – mostly because 3G is inherently not as stable as we expect it to be.

The other trend is to use a SLT connection if you already have a land line connection to your home. It’s made even more simple if your idea of using the internet is to do some light browsing, watch an occasional YouTube video and connect with someone through Skype because SLT has got you covered with reasonably priced packages for the “light user” (usually uses less than 15GB per month) crowd.

Unfortunately, unless you plan on browsing purely text with all your flash plugins turned off and no downloads, 15GB will barely last the month. Most users in Sri Lanka are generally medium bandwidth users who can use somewhere around 35GB per month. This segment mainly uses Facebook, a bit of YouTube, maybe a Game of Thrones episode or a Hindi film every now and then. Almost all fixed bandwidth ISPs have competitively priced packages in this range.

Another bunch of users exist who do fairly heavy downloading – sometimes their usage can shoot up to around 60GB per month. These users download games, movies, TV Shows in addition to YouTube upload / download and standard browsing. At this range, most other ISPs fall off, with SLT, Dialog and Lankabell being pretty much the only cost-effective choices.

Finally there are the heavy users who download everything they see on the internet, sometime for the sake of downloading. They download everything from music, games and movies to software. If you are a gamer you can find yourself pushed into this category with the increasing download sizes for game related content.


Initially SLT, with their “unlimited” 512 KBps packages, were the undisputed choice for heavy users. As of late, however, SLT has been notorious for waging a covert war against these users to reduce their usage. The crux of the problem was that SLT initially offered unlimited connections for early users when they introduced broadband. Once SLT migrated to capped connections, these unlimited users could not be converted unless the users were willing to. SLT relies throttling techniques (basically slowing down your connection intentionally) to force those users to switch to newer capped connections. Unlimited connection are now, for all practical purposes, so heavily capped at certain intervals that they are basically very slow capped connections.

Dialog and Lanka Bell seems to be eager to jump into fulfill the needs of these heavy users who are frustrated with SLT’s heavy handed tactics. Both of them focus on different ends of the segment: Lanka Bell seems to favor expensive but unlimited connections for the true downloader, while Dialog strikes for a speed / price / cap balance.

However, it should be noted that most of the traffic from these heavy users are pirated material downloaded and uploaded through Peer to Peer(P2P) software. In some countries ISPs enforce strict restrictions on P2P usage. It’s interesting to see whether Sri Lankan ISPs would adopt this strategy in the future.

The Future: where do we go from here?

There are two sides of the coin here:
On one hand, data is genuinely expensive. Being the small country that we are, our connections to the outside world are woefully small compared to the likes of the US, and we are heavily reliant on Singapore for our data. ISPs pay quite a lot per megabyte – just enough to make a profit, though. Until the government and corporations focus and this and perhaps invest in another cable and the appropriate infrastructure, we’re not going to see radical changes. Cost per GB will go down at a slow rate.

In any case, we’re not likely to catch up with the gigalithic infrastructure of America, so comparisons are moot. At least we’re way cheaper than Brazil.

The other frontier is service, packages and uptime. SLT seems to be a running joke among most of Sri Lankan internet users: this is a niche Dialog and, to a lesser extent, Lanka Bell, are trying to exploit.Lanka Bell seems focused on providing unlimited amounts of data, while Dialog aims for a balance. The TRCSL is playing a big role in this regard – their policy is to lower the cost per bandwidth by encouraging competition among ISPs (which we’re already seeing).

On the other hand, we have data caps, which are truly too small in the increasingly data-heavy world we live in. For example, this 2012 map indicated we had the lowest entry level broadband cost in the world, but this is for entry level packages which are not adequate. The cost gets relatively high when the bandwidth and data caps get into acceptable ranges. This should be one area our policy makers should focus on if we plan to use the internet as tool to develop the knowledge of our citizens: find a way to make our ‘net cheaper.



  1. good write up. however on “At the time most household connections were 64kbps dial up connections used mostly by enthusiasts” 64kbps needs to be changed to 14.4kbps and that’s where dials were started. 64kbps was super luxury back then and it was only offered as lease circuits.

  2. Interesting article.

    But still couldn’t find the chart this paragraph says: “Chart above represents the internet and e-mail subscriber growth, where the blue line represents fixed line users and the red line represents the mobile users.” 😛

  3. Apart from the intentional throttling of bandwidth for unlimited package users, SLT is pretty reliable. Their capped packages are not so bad for a normal users. Heavy downloaders are mostly pain in the a** anywhere. They deserve to be limited to give the fair share of available bandwidth to other common users. Having said that, there are some people who knows how to use resources shared with others properly even though they like downloading stuff. With SLT I haven’t had an issue with bandwidth with their capped packages. Speed is just as they promised.

    Also I’m a Dialog 4G user from the beginning. It was way fast even hit 50mbps at my friend’s place, but the reliability goes down with the time when more users connect to the tower. Response time goes down drastically but once you get the response, the data flows much faster. Good for downloads but worst for browsing, FTP access, SSH etc. Same results in Col 09, Col 03 and Col 04 where I used them.

    For me SLT is #1 for reliable connectivity. Dialog is dependable. No idea about Lanka bell coz haven’t used their services. Having said that, SLT still have enough space to improve like setting up new connections.

    But the future seems promising regarding the internet infrastructure of our country. Let’s wait and see.

  4. So what’s your opinion on the best option? I work from home in Colombo, and download a large number of video files to work. Probably about 120GB per month. Currently with SLT, keen to hear your thoughts on whether Dialog or Lankabell would be a better option.

  5. SLT 512 KBps unlimited package currently charged Rs. 1,600/- + taxes as rental.
    Where as Lanka Bell & Dialog 4 G offer 4 MBps speed with average bandwidth 25-35 GB for a lesser price.
    Therefore it’s pointless to be with SLT

  6. I swiched to 35gb package from an unlimited one.. now feeling kind of restricted specially with few hours of skype video you hit 1gb a day without doing any browsing.. btw youtube and chromecast combo can easily finish up the limit in couple of days. So not only P2P users use heavy data even an average subscriber can end up in th 60gb+ a month league just by browsing youtube in HD quality 😉

    PS: switching back to unlimited

  7. hi,i am nuwan. i walking in Lanka bell. now over router price only Rs.1990/=.
    packages 50 GB – Rs.950/=, 70 GB – Rs.1350/=, 140 GB – Rs.3500/= without vat)
    nuwan – 0727266018 / 0702118382

  8. This broadband pricing map is inaccurate, I lived in Russia for 7 years paid ~1000 LKR per month to get a 100 Mbps speed and I used almost 250 GB per month, there were no caps and no connection charges….. SLT and Dialog have different reasons to hike the price of DATA. Don’t be fooled by inaccurate information. But I do admire the effort of trying to give a detailed report.

  9. I have an SLT fibre optic connection which gives a measured 110 Mbps download speed on my Ethernet connection with the SLT router. That is the good part of the connection. The bad part of the connection is that I have a 160 MB package but always lose at least 50% of the package as I am not prepared to use the Internet between midnight and 0600. I wish there were some alternative. Perhaps Nuwan at Lanka Bell might have a suggestion. I am still not used to the packages offered here in Sri Lanka, especially the SLT packages. I spend part of the year in Sri Lanka and part of the year in Europe and, of course, in Europe ALL of the Internet download / upload packages are unlimited.

  10. Some facts stated above are factually incorrect:
    Lanka Internet was the first entity to connect to the Internet backbone in Sri Lanka via a 64 kbps dedicated International Private Leased Circuit (IPLC) in May of 1995. The connection was to US Sprint backbone via SEA-ME-WE 2 Fibre optic submarine cable. First commercial email server was and first commercial web site was all established by Lanka Internet. Lanka Internet established a Satellite connection to the Internet backbone subsequently for much higher speed connectivity. Sri Lanka Telecom was the second entity to connect to the Internet in Sri Lanka.
