Best eSIM for Thailand in 2026: 6 Providers Compared (Real Prices)

I'm based between Bangkok and Chiang Mai, and Thailand is the trip half my friends abroad ask me about first — usually somewhere between "should I get a visa on arrival" and "which SIM do I buy." My answer for the last few years has been: don't buy a physical SIM at all, just get an eSIM before you land. Here's what the six providers we track actually charge for Thailand right now, checked against their real Thailand-specific pricing, not a generic Asia rate.

The quick answer

• Best overall deal in this whole comparison: Nomad eSIM's Unlimited 30-day plan at currently unavailable — dramatically cheaper than every other 30-day unlimited option here.
• Best short unlimited deal: eSIMCard's 7-day unlimited at $14.94 — the cheapest short unlimited tier across everything we checked. If you specifically want 10 days, Nomad eSIM's Unlimited 10-day plan at $15.00 is the better pick.
• Cheapest possible entry point: Ubigi's 1GB/1-day plan at $2.00 is the outright cheapest tier we found. If you want a full week instead of one day, Saily's 1GB/7-day plan at $2.99 is the best value.
• Best fixed-data value for a month: Ubigi's 20GB/30-days at $12.00 — well ahead of Airalo's 20GB/30-days at $18.00.

What you'll actually pay: six providers compared

Airalo

Airalo has one of the deepest Thailand lineups of any provider we checked, with real granularity between 3, 5, 7, 10, 15, and 30 days. A 1GB/3-day plan is $4.00, 3GB/7-days is $6.00, 10GB/7-days is $10.00, and the 30-day tiers run 5GB at $8.00 up through 50GB at $27.50. Unlimited tiers start at $9.50 for 3 days and run to $49.00 for a full month.

eSIMCard

eSIMCard has replaced Holafly in this comparison — Holafly no longer has an active affiliate relationship with us, so we don't feature it even though its plans are still technically for sale. eSIMCard's Thailand lineup is genuinely deep and competitively priced: Unlimited runs from $2.97 for 1 day up through $45.00 for 30 days, with a full ladder of stops in between (7 days at $14.94, 15 days at $25.84). Fixed-data options exist too — 10GB for 30 days is $15.95 and 20GB for 30 days is $27.69 — though Ubigi undercuts it on fixed data, below.

Nomad eSIM

Nomad eSIM is the one to beat for Thailand specifically. Its Unlimited 10-day plan is $15.00, and its Unlimited 30-day plan is currently unavailable — less than half of what Airalo, Ubigi, or Maya Mobile charge for the same 30 days, and dramatically less than Saily's 30-day unlimited (more on that below). On the fixed-data side, 10GB for 30 days is $10.00 and 5GB for 30 days is $8.00, both genuinely cheap. If you're only buying one eSIM for a Thailand trip, start by checking Nomad eSIM's price against whatever else you're considering.

Saily

Saily's 1GB/7-day plan at $2.99 is still one of the cheapest short-trip tiers we found, and its fixed-data 30-day tiers remain competitive: 20GB is $19.99, 10GB is $10.99, 5GB is $7.99. Its unlimited pricing, though, has moved up noticeably since we last checked — 30-day unlimited is now $59.99, making it the most expensive 30-day unlimited option in this whole comparison, well above Airalo, Ubigi, Maya Mobile, and Nomad eSIM alike. If you want unlimited data for a full month in Thailand, Saily is no longer the one to reach for — its fixed-data tiers are still worth a look, its unlimited tiers aren't the value they used to be.

Ubigi

Ubigi's Thailand fixed-data pricing rewards anyone willing to look past the homepage: 20GB for 30 days is $12.00, 5GB for 30 days is $6.00, and a 1GB/7-day starter is $2.50 — or go even shorter with a 1GB/1-day tier at $2.00, the cheapest single tier in this whole comparison. It also sells annual allowances for frequent visitors — 24GB spread over 12 months for $27.00, or 60GB over 12 months for $39.00 — which is unusual among the six and worth knowing about if you're in and out of Thailand regularly rather than on a single trip. Its unlimited tiers (7 days at $22.00, 15 days at $35.00, 30 days at $49.00) are reasonable but not the standout the fixed-data side is.

Maya Mobile

Maya Mobile charges the same flat rate here as everywhere it operates: $9.99 for 3 days, $19.99 for 7 days, $27.99 for 14 days, $49.99 for 30 days. For Thailand specifically it's mid-pack — Nomad eSIM and eSIMCard both undercut it at every duration where they overlap. Where Maya still makes sense is if Thailand is one stop on a longer multi-country trip and you'd rather manage one eSIM for the whole journey than juggle a Thailand-specific plan alongside separate ones for each other country.

Why the prices are all over the place

People message me all the time asking why one Thailand eSIM plan can cost three or four times another for the same rough duration. It's not a scam on either end — it's different pricing models colliding. Maya Mobile charges the exact same flat rate everywhere it operates, which is why it's competitive but not the outright winner here — Nomad eSIM, which prices Thailand specifically and aggressively, undercuts it. Saily's unlimited tiers, on the other hand, have simply gotten more expensive since we first compared these six — a reminder that these numbers move in both directions, not just downward. And Airalo, Nomad eSIM, Saily, Ubigi, and eSIMCard all sell a mix of fixed-data and unlimited, so the cheapest "unlimited" headline isn't automatically the cheapest plan for your actual usage.

My honest take after years of doing this: most people massively overestimate how much data they need on a Thailand trip. Grab, Google Maps, messaging apps, and social media scrolling add up to far less than people assume — a 10GB or 20GB plan from Airalo or Ubigi covers a normal two-week trip for most travelers, at a fraction of what unlimited costs.

How to pick based on your trip

A short island-hop or city stop, light data use: Saily's 1GB/7-day plan at $2.99 covers the basics — maps, messaging, social media — for a full week. If you only need a single day, Ubigi's 1GB/1-day at $2.00 is even cheaper.

A week to ten days, and you want unlimited: eSIMCard's 7-day unlimited at $14.94 is the best value we found at that length. If you specifically need the full 10 days, Nomad eSIM's Unlimited 10-day plan at $15.00 is the better fit.

A full month, fixed data is enough: Ubigi's 20GB/30-day plan at $12.00 is exceptional value — most travelers don't come close to using 20GB in a month of normal use.

A full month, and you want unlimited: Nomad eSIM, at currently unavailable — less than half of what Airalo, Ubigi, or Maya Mobile charge for the same duration, and far cheaper than Saily's current 30-day unlimited price.

You're combining Thailand with other Southeast Asian countries: a regional or global plan can simplify things, but check the per-day math against Nomad eSIM's Thailand-specific pricing first — it's genuinely one of the cheapest destinations in our entire dataset, and a single-country plan may still beat a regional one.

A few things worth knowing before you buy

Bangkok, Chiang Mai, Phuket, and the other major tourist areas all have strong, fast coverage — this is one of the more reliable eSIM destinations we track. Smaller islands and rural areas up north can be patchier, which is true of local SIMs too, not just eSIMs.

Install before you fly. Every provider here lets you activate the eSIM only once you land, so there's no reason to wait until you're at Suvarnabhumi hunting for airport wifi to scan a QR code.

Check your phone is eSIM-compatible and carrier-unlocked before you buy — it takes about a minute, and our beginner's guide to eSIMs walks through exactly how.
