Best eSIM for Sri Lanka in 2026: 8 Providers Compared (Real Pricing)

Sri Lanka is one of those destinations where the size of the island tricks you — Colombo to Kandy to Ella to Mirissa can eat up ten days easily, and you'll want reliable data the entire way: booking last-minute seats on the hill-country train line, checking tuk-tuk fares, translating menus, and mapping temple visits that Google Maps still gets slightly wrong. I get asked about Sri Lanka eSIMs constantly by friends passing through Bangkok on their way there, so here's the real pricing, pulled straight from the 122 providers we track for the island specifically.

The good news is that Sri Lanka's eSIM market is genuinely competitive — you're not choosing between "cheap and unreliable" and "expensive and safe" the way you sometimes are elsewhere. The differences below come down to how each provider has packaged the same underlying network access, not how good the connection actually is once you land.

Quick-answer picks

• Cheapest short trip (~1GB): Revo eSim — $2.65 for 7 days
• Best value for a week (~5GB): Orbit Mobile — $7.50 for 30 days

Provider-by-provider breakdown

Orbit Mobile is the sharpest all-round value for Sri Lanka. Every tier — 1GB, 3GB, 5GB, 10GB, and 20GB — runs a flat 30-day validity, and the pricing beats or matches almost everyone else at the same size: $3.50 for 1GB, $7.50 for 5GB, $10.50 for 10GB, $17.50 for 20GB. If you're not sure exactly how the trip will go, Orbit Mobile is the safest default.

Revo eSim undercuts everyone on the smallest tier — $2.65 for 1GB over 7 days — making it the pick for a short beach hop or a long layover. Its larger tiers (10GB/30 days at $16.35, 20GB/30 days at $31.69) run more expensive than Orbit Mobile's equivalent sizes, though, so it's really a "small trip" specialist rather than an across-the-board winner. It's also one of only a few providers to offer a genuinely long-validity option: 50GB valid for 180 days at $98.55, useful if you're making repeat trips to Sri Lanka over the year on one eSIM.

eSIMo runs a simple five-tier fixed ladder from 1GB/7 days ($3.90) to 20GB/30 days ($22.90) — consistently a few dollars above Orbit Mobile at every matching size, but a fine choice if you already have an eSIMo eSIM installed from a previous trip elsewhere.

Ubigi is the one to reach for if fixed-data tiers don't fit your plans. It sells three separate unlimited windows (7, 15, and 30 days, at $24.00, $44.00, and $65.00) alongside a genuinely large 50GB/30-day bundle for $39.00 — the biggest single fixed bundle of any provider we track here, and cheaper than buying Ubigi's own 30-day unlimited plan if 50GB is realistically enough for you.

Maya Mobile sells unlimited-only, across four fixed windows: $9.99, $19.99, $27.99, $49.99 for 3/7/14/30 days. For a full month, it's meaningfully cheaper than Ubigi's own unlimited tier — if unlimited is specifically what you want for a longer stay, Maya is the better buy.

eSIMGlobe has by far the deepest tier catalog of any provider here — dozens of distinct data/duration combinations, from a 500MB/1-day plan at currently unavailable up to a 70GB/14-day plan at currently unavailable. It's the provider to check if your trip length is unusual (say, exactly 5 days) and you don't want to round up to a week-long or month-long bundle you won't fully use.

co:sim prices similarly to eSIMGlobe at the small end but runs noticeably higher at larger sizes — its own 50GB/180-day option costs $122.99, more than either eSIMGlobe's or Ubigi's roughly-equivalent bundles.

Bcengi is a prepaid, per-GB wallet rather than a bundle: roughly $1.81 per gigabyte actually used, with no expiry date. It's the most forgiving option if you genuinely don't know how much data an unpredictable Sri Lanka itinerary will burn through.

Why prices vary this much

The eSIM you buy is really just a resold slice of wholesale data-roaming capacity that some local Sri Lankan network has agreed to sell in bulk. Every provider on this list is reselling access to the same handful of underlying networks, so the difference in what you pay comes down to the wholesale rate each one negotiated, how thin a margin they're running, and how they've chosen to slice the same raw data into tiers — some optimize for the lowest possible headline price on a specific size, others for breadth of options, others for simplicity (Maya's unlimited-only approach, for instance).

Picking by trip type

A quick stop in Colombo or a beach weekend in Mirissa: Revo eSim's 1GB/7-day plan at $2.65 covers maps, messaging, and social media without much slack, but it's enough for a short trip.

The classic 10-day hill-country-and-coast route: Orbit Mobile's 10GB/30-day plan at $10.50 gives you real breathing room for navigation, photo uploads, and video calls home, at a price that doesn't need much thought.

A longer stay, working remotely from Colombo or Galle: Maya Mobile's 30-day unlimited plan at $49.99 removes the need to track usage entirely — the better move than Ubigi's pricier unlimited tier for the same month.

Multiple short trips across the year: Bcengi's per-GB wallet at roughly $1.81/GB never expires between visits, so you're not re-buying a fresh bundle, and losing whatever's left over, every time you land.

Practical caveats

None of the providers we track publish bundled voice minutes or SMS for Sri Lanka — every plan here is data-only. Keep your home number for calls and texts, or route calls through a VoIP app over the eSIM's data connection instead. Also confirm your phone is eSIM-compatible and carrier-unlocked before you fly (our eSIM compatibility guide shows the quick settings-based check that works regardless of phone model) — and get the eSIM installed and activated before you land, since airport Wi-Fi in Colombo isn't always dependable enough to trust for a first-time QR code scan.
