Best eSIM for Sri Lanka 2026: 6 providers compared

Part of our Sri Lanka eSIM guide: all articles and key facts →

The best eSIM for Sri Lanka depends on how long you stay, how much you stream and which network you end up on. Almost every travel eSIM we read runs on SLT-Mobitel, the fastest network in Opensignal's latest report, but only one seller lists Dialog, the network that won every coverage award. The "unlimited" plans also hide very different caps, from 2 GB a day to 60 GB a month at full speed.

We read the Sri Lanka pages of six providers on 22 October 2026 and compared price, network and the rules that matter between Colombo, the Cultural Triangle, the Kandy to Ella train and the south coast. Prices are quoted in the currency each seller displayed, with euro conversions at the ECB rate where a page showed only dollars.

Which is the best eSIM for Sri Lanka?

For unlimited data, Yesim was the cheapest verified plan priced in euros for a day, a long weekend, ten days, two weeks and a month, and Ubigi for a week; eTravelSim undercut it in dollars for 7, 15 and 30 days. For a fixed allowance, Airalo and Ubigi led. Here are the winners by need, on prices checked on 22 October 2026:

• A stopover or a single day in Colombo or Negombo: Yesim sells 1 day of unlimited data for €3.50, Holafly for €5.90.
• A long weekend (3 days): Yesim costs €10.50, Airalo €11.50 and Holafly €12.50.
• Five days: Yesim and Airalo both cost €17.50, Holafly €19.50 and Nomad $26 (about €23.20).
• One week, the classic Sigiriya, Kandy and Ella loop: eTravelSim costs $19 (about €16.96), Ubigi €24 for 20 GB at full speed, Yesim €24.50, Airalo €25 and Holafly €25.90.
• Ten days, enough to add the south coast: Yesim costs €29.94, Airalo €32.50 and Holafly €34.90.
• Two weeks to a month: Yesim costs €39 for 15 days and €57 for 30 days; eTravelSim $39 and $59 (about €34.81 and €52.65); Ubigi €44 and €65.
• A light user who wants a fixed allowance: 10 GB valid 30 days costs €11 at Airalo or Ubigi, and 20 GB valid 30 days €17 at Airalo or $17.99 (about €16.06) at eTravelSim.
• A Sri Lankan number for calls and SMS: Airalo's Hutch-based package includes 200 minutes and 200 SMS with 20 GB for 30 days at €18.50.
• Access to Dialog: Holafly is the only seller we read that lists Dialog alongside Mobitel and Hutch.

If you fly on to Malé, read our Maldives eSIM guide: none of the Sri Lanka plans above covers the Maldives, so you will need a second plan or a regional one.

The Sri Lanka eSIMs side by side

The table lists the Sri Lankan network each provider names, its unlimited week and a typical fixed plan. All figures were read on the providers' own pages on 22 October 2026 and are quoted in the currency each page displayed.

Unlimited prices by length tell the rest of the story. Yesim and Holafly sell any number of days; Airalo sells 3, 5, 7, 10, 15 and 30 days; Ubigi and eTravelSim sell 7, 15 and 30 days.

The comparison database esimdb listed 13,955 plans from 244 providers covering Sri Lanka on 22 October 2026, so this is a sample of well-known sellers, not the whole market. Saily also sells Sri Lanka plans, but its page refused automated reading on 22 October 2026, so we leave it out of every verdict.

What does "unlimited" really mean on a Sri Lanka eSIM?

It means anything from 2 GB a day at full speed to 60 GB a month, and only some sellers publish the figure. Here is what each page said on 22 October 2026:

• Airalo: "Lower speed rate of 1 Mbps after 3 GB usage per day" on every unlimited plan.
• Nomad: "2GB/day at 4G/5G. 1 Mbps after 2GB", the tightest cap we found.
• Ubigi: a total rather than a daily cap: 20 GB at full speed for 7 days, 30 GB for 15 days and 60 GB for 30 days, then 2 Mbps (see the 30-day plan page).
• Holafly: operators may apply a fair usage policy "for no more than one (1) day", with no data threshold given.
• Yesim: "Data speed may be limited in accordance with the network operator's Fair Usage Policy", without a figure.
• eTravelSim: no speed rule on its page for the unlimited plans.

For maps, messaging and a few uploads, 3 GB a day is plenty. Heavy streamers will find Ubigi's monthly pool more forgiving than a daily cap.

Compare with the local option: SLT-Mobitel's 30-day tourist plan offers "Non-stop Data" for Rs 5,131 (about €13.76), but the page adds "FUP and Conditions apply" without stating the threshold.

Dialog, Mobitel or Hutch: which network does each eSIM use?

Most travel eSIMs put you on SLT-Mobitel, which won all four speed awards in Opensignal's latest Sri Lanka report; Dialog, the coverage leader, is listed only by Holafly. Sri Lanka has three mobile operators: Dialog Axiata, SLT-Mobitel and Hutch. Airtel Lanka no longer exists as a separate company: Dialog completed its amalgamation with Airtel Lanka on 30 August 2024 and kept the Airtel brand.

On the seller pages, Airalo's data plans are a "4G Data-only eSIM working on Mobitel network"; Yesim names Mobitel (3G and LTE); eTravelSim names Mobitel; Nomad names "Hutch / Mobitel"; Ubigi names Hutch and Mobitel; Holafly lists "Mobitel (Pvt) Ltd / Dialog Axiata PLC / Hutch Sri Lanka". Airalo also sells a separate Hutch package with minutes and SMS.

The independent figures come from Opensignal's Sri Lanka Mobile Network Experience report of February 2026, built from measurements by its users between 1 October and 29 December 2025:

Opensignal named Dialog "Best Network" with eight outright wins, while SLT Mobitel took all four speed awards. Both launched commercial 5G in December 2025 after the regulator's spectrum auction; Hutch did not bid. The more recent Ookla Speedtest Global Index put Sri Lanka's median mobile download at 57.24 Mbps in September 2026, all operators combined.

For a traveller, the practical gap is between Mobitel or Dialog on one side and Hutch on the other. A plan that names Hutch and Mobitel, like Nomad's or Ubigi's, can usually pick Mobitel; check in your phone's network settings which operator you are on if speeds feel slow.

Pros and cons of each provider

Each provider below was read on 22 October 2026. Prices are for Sri Lanka-only plans.

Yesim

Pros: the cheapest verified euro-priced unlimited plans for 1, 3, 10 and 30 days (€3.50, €10.50, €29.94, €57) and joint cheapest for 5 days; any length from 1 to 30 days; validity "begins upon connection to a compatible network" and the plan can be activated within 180 days of purchase; "ID verification: Not required". Cons: Mobitel only; hotspot "depends on operator"; no figure for the fair usage limit; fixed plans are shown as large discounts on list prices.

Airalo

Pros: a clear published cap (3 GB a day at full speed, then 1 Mbps); cheap fixed plans (10 GB for 30 days at €11, 20 GB at €17, 50 GB at €33.50); the only seller we read with a Sri Lankan number option, on Hutch. Cons: its data plans run on Mobitel only; no hotspot rule on the page; the Hutch package starts its validity at installation and asks for a Sri Lankan address by SMS.

Holafly

Pros: the only seller we read that lists Dialog as well as Mobitel and Hutch; any length of unlimited data; 1 GB a day of shared hotspot data; an honest coverage warning for "certain parts of Yala and Wilpattu national parks, along routes in the Knuckles Mountain Range, and in some isolated areas of the Central Highlands". Cons: the most expensive unlimited plan at every length we compared (€25.90 a week, €68.90 a month); no fixed plans.

Ubigi

Pros: a monthly pool rather than a daily cap (20 GB at full speed for a week, 60 GB for a month); "Smartstart" starts the plan on arrival; "Data sharing allowed"; 10 GB for 30 days at €11. Cons: names Hutch first and Mobitel second, and you cannot choose in advance; only 7, 15 and 30-day unlimited plans.

Nomad

Pros: hotspot supported; 20 GB valid 30 days for $21 (about €18.74); the plan starts on connection and can be activated up to 60 days after purchase. Cons: unlimited only for 5 and 10 days, at $26 and $45, with the tightest cap we found (2 GB a day, then 1 Mbps); prices in US dollars.

eTravelSim

Pros: the cheapest unlimited plans we found for 7, 15 and 30 days ($19, $39, $59); cheap fixed plans (20 GB for 30 days at $17.99). Cons: Mobitel only; hotspot "Allowed in limited data plans Only", so not on unlimited; no published speed rule; its page says eSIM activation is "Automatic after installation", so install it just before you fly; prices in US dollars.

Is a Dialog or Mobitel tourist SIM cheaper than a travel eSIM?

Yes, by a wide margin, if you can spend a few minutes at a counter after landing. On 22 October 2026, Dialog's tourist page listed three plans billed as a "Monthly Rental": 20 GB for Rs 1,399, 30 GB for Rs 1,799 and 50 GB with unlimited WhatsApp for Rs 2,450, each with a small call credit. At the Central Bank of Sri Lanka's indicative rate of 22 October 2026 (Rs 372.90 to the euro), that is about €3.75, €4.82 and €6.57.

SLT-Mobitel's tourist packs include unlimited local calls and 1,000 SMS: 15 GB for 7 days at Rs 821 (about €2.20), 30 GB for 30 days at Rs 1,540 (about €4.13), and 30 days of "Non-stop Data" at Rs 5,131 (about €13.76).

Against that, the cheapest euro-priced travel eSIM month costs €57 at Yesim. The catch is the counter: Dialog asks you to "present your passport to a Customer Service Representative for verification" at its two airport stores after customs, and Mobitel says "You only need your foreign passport." Mobitel issues its tourist eSIM only at the arrival lobby or an outlet; its online portal is for residents with a Sri Lankan ID. Our Sri Lanka local SIM guide compares the three operators, the airport counters and the online options in detail.

Many travellers combine both: a small travel eSIM for the first hours, then a local line.

Which eSIM should you pick for your trip length?

Yesim for euro-priced unlimited data at almost any length, eTravelSim if you pay in dollars and never need a hotspot, Ubigi if you want a large monthly pool, and Airalo or Ubigi for a fixed allowance. Here is how the choice plays out on typical itineraries.

A few days in Colombo and Negombo

Bandaranaike International Airport lies about 32.5 km north of Colombo, close to Negombo. For 3 days, Yesim's €10.50 is the cheapest verified unlimited plan; a light user will be fine with Airalo's 3 GB for 7 days at €6.

One week in the Cultural Triangle and Kandy

Sigiriya, Dambulla, Polonnaruwa and Kandy make a dense week of driving and climbing. Ubigi's €24 week with 20 GB at full speed and Yesim's €24.50 week are the best euro-priced options; eTravelSim's $19 week is cheaper but without hotspot, which matters if your driver's tablet or a travel companion shares your connection.

Ten days to two weeks with the train to Ella and the south coast

Yesim's 10 days at €29.94 and 15 days at €39 are the cheapest euro-priced options; eTravelSim's 15 days cost $39 (about €34.81). If you will tether a laptop in Ella or Mirissa, prefer Holafly (1 GB a day of hotspot) or Nomad and Ubigi, which allow sharing.

A month or more

Yesim's €57 for 30 days is the cheapest euro-priced month, eTravelSim's $59 the cheapest in dollars. For that length, a local tourist SIM is the obvious saving: Dialog's monthly 50 GB plan costs about €6.57.

Sri Lanka and the Maldives

The Maldives is a common second leg, and none of the Sri Lanka plans we compared covers it. See our Maldives eSIM guide; if you are comparing Indian Ocean destinations, our guides to the best eSIM for Mauritius and the best eSIM for the Seychelles apply the same method.

Will an eSIM work on the Kandy to Ella train, in Yala and on the south coast?

In towns and along the main roads, yes; on the mountain stretches of the railway and inside the parks, expect gaps whatever you buy. No operator publishes coverage figures for individual routes or parks, and we found no independent measurement at that level: Opensignal's report is national only, and nPerf publishes no Sri Lanka barometer.

What the national figures do say: Dialog users had the widest coverage in Opensignal's measurements (Coverage Experience 9.2 out of 10, against 7.5 for SLT Mobitel and 5.6 for Hutch), and all three networks kept users on 3G, 4G or 5G more than 90% of the time. A Mobitel eSIM is therefore a reasonable bet outside the cities, and a Hutch connection the weakest.

The Kandy to Ella line climbs through tea country to its summit at Pattipola, 1,898 m above sea level, and runs through a long series of numbered tunnels between Nanu Oya and Badulla, so short drop-outs on the train are normal. Holafly, the one seller that writes about it, warns that coverage may be weaker in "certain parts of Yala and Wilpattu national parks, along routes in the Knuckles Mountain Range, and in some isolated areas of the Central Highlands".

Download offline maps of the hill country and the parks before leaving Colombo or Kandy, and save your train e-ticket and hotel addresses offline. Our local SIM guide sets out what each network's measurements mean outside the cities.

When does the plan start, and can you share it?

Most providers let you install the eSIM at home and start the plan in Sri Lanka, but two exceptions matter. Yesim's validity begins on connection to a compatible network; Airalo's data plans start on first use; Ubigi's Smartstart starts the plan on arrival; Nomad's plans start on connection and must be activated within 60 days of purchase; Holafly's plan starts when the eSIM connects to a supported network. The exceptions: eTravelSim says activation is "Automatic after installation", and Airalo's Hutch package with minutes starts its validity at installation, so install those just before departure.

Hotspot rules differ:

• Holafly: 1 GB of shared data a day.
• Nomad: "Yes, Nomad's eSIMs support tethering / hotspot."
• Ubigi: "Data sharing allowed."
• Yesim: "Depends on operator".
• eTravelSim: limited-data plans only, not unlimited.
• Airalo: no hotspot rule on its Sri Lanka page.

Only Airalo's Hutch package includes a Sri Lankan number, with 10 to 500 minutes and SMS depending on the plan, and "International outgoing calls are not included". Keep your home line on with data roaming off if you need bank codes by SMS; our guide to running two eSIMs at the same time explains how.

What should you sort out before landing in Colombo?

Install the eSIM at home (except the two plans that start on installation), check that your phone is unlocked, and download offline maps. You will want data in the arrivals hall for a ride-hailing app or to message your driver.

• eSIM support: find your model on our list of eSIM-compatible phones. If your iPhone refuses the profile, read why an iPhone says eSIM not supported.
• Unlocked: a phone locked to your home operator will refuse a Sri Lankan profile, and Dialog itself warns that carrier-locked devices may not download its eSIM. Read do you need an unlocked phone for a travel eSIM.
• Installation: on Android, follow our step-by-step eSIM activation guide; if the line stays on "Activating", see our fixes for an eSIM stuck on activating.

If a seller asks for your phone's EID, our guide shows where to find the EID number. If nothing connects on arrival, check that data roaming is on for the eSIM line (Airalo's Mobitel plans and most travel eSIMs need it), then work through 10 fixes for a travel eSIM not working abroad.

How we compared

We read each provider's Sri Lanka page, or the plan data it embeds, on 22 October 2026, and recorded price, validity, data, network, speed rule, start of validity and hotspot rule. Where a page offered a currency choice we used euros; Nomad and eTravelSim are quoted in the US dollars they displayed and converted at the ECB reference rate of 22 October 2026 (1 euro for 1.1205 dollars). Rupee prices are converted at the Central Bank of Sri Lanka indicative rate of the same day (Rs 372.90 to the euro).

Network quality comes from Opensignal's February 2026 Sri Lanka report and Ookla's Speedtest Global Index for September 2026. Visitor numbers come from the Sri Lanka Tourism Development Authority report for January to September 2026. We did not buy the plans or measure speeds in Sri Lanka, and we could not read Saily's page. Prices change often, so check the provider's page before you buy.
