The best eSIM for Thailand and Singapore in 2026.

Bangkok to Singapore is a short flight, and one Asia eSIM covers the whole route. I priced six brands on the same day, set them against Ringo Light, and tell you where a rival is the better buy.

Cheapest unlimited eSIM for Thailand and Singapore: Ringo Light, $34.99 for 2 weeks and $59.99 for 30 days (Ubigi $45 and $66). Prices read 25 October 2026.

The short answer

Bangkok, the islands, then Singapore on the way home is a trip I see planned a lot. I priced the six Asia regional plans on 25 October 2026 for a week, two weeks and a month, read what unlimited means at each brand, and added up what Ringo Light charges for its Thailand and Singapore plans separately. The sums are closer here than on other routes, so I show them in full.

What to do in Thailand and Singapore, and what your phone needs for it

Seven places a trip across Thailand and Singapore often includes, with the one thing your data does for you at each. Both countries are on Ringo Light's Asia plan, so one eSIM works from Bangkok to the Singapore skyline.

The Grand Palace and Wat Phra Kaew, Bangkok
BangkokThe Grand Palace and Wat Phra KaewThe former royal palace and the temple of the Emerald Buddha share one walled compound by the river. Go at opening time, before the heat and the tour groups, and cover your shoulders and knees.✓Ignore anyone outside who says the palace is closed today; check the official site on your phone instead.
Wat Arun, Bangkok
BangkokWat ArunThe Temple of Dawn rises across the Chao Phraya from the palace, its tower covered in pieces of porcelain. It glows at sunset from the east bank.✓The cross-river ferry takes cash only; a maps app shows which pier it leaves from.
Maya Bay, Koh Phi Phi
Koh Phi PhiMaya BayThe cove from the film The Beach, closed for years so its reef could recover and now open again with swimming banned. Boats leave from Phuket, Krabi and Phi Phi Don.✓The bay closes to visitors for part of each year; check the national park page before you book the boat.
Railay, Krabi
KrabiRailayA peninsula cut off by limestone cliffs, reached only by longtail boat from Ao Nang. Climbers come for the walls and everyone else for the beaches at West Railay and Phra Nang.✓Look up the tide times: at low tide the longtails drop you in the shallows and you wade in.

One plan for both countries: Ringo Light

Thailand and Singapore are linked by short, cheap flights, and a regional eSIM means one install and no change at the border. Two country eSIMs mean installing the second one in a hotel in Bangkok or a hostel room in Singapore, and paying twice. I would take the single plan.

I read Ringo Light's Asia plan at $34.99 for 2 weeks and $59.99 for 30 days, and nothing renews. For about two weeks of regional unlimited, I read Ubigi at $45 for a fixed 30 GB at full speed, Airalo at $49, Holafly at $51.50 and Saily at $54.99. For a month, $66 to $86.99.

Ringo Light's country plans are cheap here, so the gap with the Asia plan is smaller. Thailand's 2 weeks is $22.99 and Singapore's $17.99 on their own pages, $40.98 together, against $34.99 for the Asia trip that covers both. For a month, Thailand's 30 days is $32.99 and Singapore's $29.99, $62.98 together, against $59.99.

That month is only $2.99 apart, so I would weigh the install. If you spend nearly all of the month in one country, its own page wins: Thailand's 30 days at $32.99, or Singapore's at $29.99, each beats $59.99. Singapore's page also sells 3 days of unlimited at $8.99, which the Asia plan lacks.

Which plans cover both countries

Ringo Light covers both. Thailand and Singapore are on its list of 20 countries, so one eSIM works in each, at one price and with the same terms.

For the rivals, the Asia post gives me their country counts (Airalo 18, Holafly 16, Saily 22, Nomad 14, Ubigi 17) and the few countries some of them leave out. Neither Thailand nor Singapore is one of those. I could not confirm both on each brand's own list on the day, so I would read the list for your plan before you buy.

If your route reaches Malaysia, Ringo Light covers it too, on the same eSIM. If it reaches Laos, it does not, and Airalo and Holafly list Laos.

If you want a data bucket: Nomad or Airalo

  • Nomad, $21 for 10 GB. Its APAC plan, 14 countries, has the lowest 10 GB price, and 20 GB for 45 days at $35 (on sale, regular $40).
  • Airalo, $25 for 10 GB. Asialink covers 18 countries. 20 GB for 30 days is $39, and buckets start at $4 for 1 GB.
  • Ubigi, $28 for 10 GB. Best Asia, 17 countries. Its 20 GB at $19 is a monthly plan and renews until you stop it.
  • Saily, $35.99 for 10 GB. Asia and Oceania, 22 countries, and no 20 GB bucket on its listing when I read it on 25 October 2026.
  • ✓Ringo Light, no buckets. It sells unlimited only: 2 weeks at $34.99, 30 days at $59.99. A fixed 10 GB costs less at Nomad and Airalo, and 20 GB costs less at Nomad, Airalo and Ubigi's monthly plan. I would buy Ringo Light for unlimited, not for a bucket.

What Ringo Light is

Ringo Light is Ringo's own data eSIM. I write for Ringo, so judge my picks with that in mind. It is sold to fund the full Ringo, one plan that works everywhere with your own number ported onto it. For Asia it sells two trips across 20 countries, Thailand and Singapore among them, both unlimited data at full speed: 2 weeks at $34.99 and 30 days at $59.99. Nothing renews. The eSIM arrives by email in seconds and installs with one scan, no app.

The card to buy it is further up this page, just after the side-by-side table.

Pick by trip

A week in Thailand only

I would read the Thailand page. Ringo Light sells no week, and its Thailand 2 weeks at $22.99 costs less than the Asia plan.

A stopover of three days in Singapore

Ringo Light's Singapore page sells 3 days at $8.99. On the regional plan, Airalo unlimited, 3 days, is $11.50.

Two weeks across both countries

I would buy Ringo Light unlimited, 2 weeks, $34.99, less than any rival charges for two weeks on a regional plan.

A month, working from cafes in both

I would buy Ringo Light unlimited, 30 days, $59.99, unless most of the month is in one country, where its own page costs less.

Light use, budget first

I would buy Nomad 10 GB for 30 days at $21, if its 14 countries include both of yours.

You need your own number to keep ringing

No travel plan here does that. The full Ringo, which Ringo Light funds, ports the number you have.

Frequently asked questions

Does one eSIM work in both Thailand and Singapore?+
Yes, on a regional Asia plan. Ringo Light's covers both on one install at one price. For the rivals I would read the country list on the brand's page first.
Which eSIM is cheapest for a Thailand and Singapore trip?+
For two weeks or a month of unlimited data, I would buy Ringo Light: $34.99 for 2 weeks and $59.99 for 30 days on 25 October 2026, against $49 and $73.50 at Airalo. For 3 days, Airalo at $11.50. For a 10 GB bucket, Nomad at $21.
Is unlimited really unlimited?+
Every brand has a limit somewhere, and I read each one. Airalo slows you after 3 GB a day, Saily after 5 GB, Nomad after 2 GB, Ubigi after its fixed full-speed amount. Holafly states no daily cap for your own phone. Ringo Light is unlimited data at full speed.
Should I buy two country eSIMs instead?+
For two weeks, not in my reading: Ringo Light's Thailand and Singapore plans cost $40.98 together, against $34.99 for the Asia plan. For a month the gap is $62.98 against $59.99, so it is close, and I would still take one install over two.

How we compared, and our sources

Airalo, Holafly, Saily, Nomad, Ubigi, Ringo Light

We priced Airalo, Holafly, Saily, Nomad, Ubigi and Ringo Light for Thailand and Singapore on 25 October 2026, all on the same day, in US dollars. Each rival's price comes from its own website where it showed dollars, otherwise from an esimdb.com listing, and every source and its date is listed below. Ringo Light's prices come from the catalogue our checkout charges.

We compare the trips people actually book: a week, two weeks and a month of unlimited data, and a 10 GB bucket. We read each brand's fair use and speed rules and quote them as the brands state them. We did not run speed tests, so this page makes no speed claims for any brand.

Ringo Light is our own product. We put it in the table on the same terms as everyone else, and where a rival is the better buy the page says so.

Left out: Maya Mobile. We could not read its own prices for this country on the day, so it stays out rather than being guessed.

Written and priced by the Ringo team. Prices change often; if you spot one that has moved, tell us through the contact page and we will update the table.
