Best eSIM for Thailand: detail guide
1.esimNB
✅ Top-up & hotspot avaliable
✅ Supports over 140+ countries
✅ Plans start from $1.50
esimNB partners with established eSIM suppliers across Asia and offers affordable plans with broad 5G network coverage.
For its Thailand eSIM, esimNB connects to major Thai carriers AIS and TrueMove H, both known for strong nationwide coverage and reliable 5G performance.
This means you can travel around Thailand without worrying about losing signal.
The data plans range from 1GB to 50GB, starting at just $1.50, making them one of the most budget-friendly options on the market.
| Destinations | Duration | Data Plans | Price (USD) |
|---|---|---|---|
| Thailand | 7 days | Total 1GB | $1.50 |
| Thailand | 30 days | Total 3GB | $4.00 |
| Thailand | 30 days | Total 5GB | $5.50 |
| Thailand | 30 days | Total 10GB | $9.50 |
| Thailand | 30 days | Total 20GB | $16.50 |
If you often watch YouTube or browse Instagram, the Thailand 10GB / 30 Days eSIM is a solid choice for everyday use.
esimNB supports hotspot sharing, data top-ups, and provides an online dashboard to check your remaining data. There’s also a clear step-by-step installation guide, making it beginner-friendly.
Customer support is available through WhatsApp and email, handled by real agents — though replies may take 1–6 hours depending on the time of day.
Overall, esimNB is a great pick for travelers who value simplicity, flexibility, and cost-effectiveness over brand recognition.
2.Yesim
Yesim’s Thailand eSIM supports DTAC and AIS networks.
Unlike esimNB, which uses TrueMove H, Yesim connects through DTAC. In terms of pricing, Yesim’s Thailand eSIM tends to be slightly more expensive than esimNB’s plans.
When comparing network coverage and signal performance between TrueMove H and DTAC, both are among Thailand’s major telecom operators.
However, earlier reports around 2020 noted that DTAC’s download speeds lagged behind its competitors.
As a result, if you plan to stay mainly in urban areas or popular tourist destinations, TrueMove H generally offers better coverage and 5G availability.
Overall, Yesim remains a solid option for travelers looking for a reliable Thailand travel eSIM, even though it may cost a bit more than esimNB.
| Destinations | Duration | Data Plans | Price (USD) |
|---|---|---|---|
| Thailand | 30 days | Total 10GB | $12.00 |
| Thailand | 30 days | Total 20GB | $19.20 |
| Thailand | 30 days | Total 30GB | $26.40 |
3. simOptions
SimOptions is one of the earlier online eSIM stores and has built a fairly solid reputation over time.
However, its website design feels somewhat outdated, and the information layout can be a bit cluttered.
That said, given its popularity and the large number of users who purchase from it, I still consider it a trustworthy option.
SimOptions doesn’t clearly specify which Thai network its Thailand eSIM supports—it only mentions 5G connectivity. The pricing is relatively high, and its eSIM plans do not support top-ups or extensions.
On the bright side, SimOptions has earned a 4.4 out of 5 rating on Trustpilot, which reflects a generally positive user experience.
| Destinations | Duration | Data Plans | Price (USD) |
|---|---|---|---|
| Thailand | 7 days | Total 1GB | $3.90 |
| Thailand | 30 days | Total 3GB | $4.90 |
| Thailand | 30 days | Total 5GB | $7.90 |
| Thailand | 30 days | Total 10GB | $14.90 |
| Thailand | 30 days | Total 20GB | $24.90 |
4.Nomad
Nomad, like Yesim, supports the same Thai mobile networks — DTAC and AIS. Their 10GB plans are also priced about the same.
One thing to note, however, is that Nomad may not offer refunds for smaller data plans, such as 1GB or 3GB packages. Since plan requirements vary by country, the supported network operators may also differ depending on the data package.
Therefore, it’s important for users to check the plan details carefully and compare options based on their specific travel needs.
| Destinations | Duration | Data Plans | Price (USD) |
|---|---|---|---|
| Thailand | 7 days | Total 1GB | $5.00 |
| Thailand | 30 days | Total 10GB | $12.00 |
| Thailand | 10 days | Total 50GB | $9.00 |
5. Alosim
AloSIM uses the AIS network in Thailand, operating on LTE rather than full 5G coverage, which makes it somewhat less advanced compared to other eSIM providers.
Its pricing is also on the higher end, making it one of the more expensive options among Thailand eSIMs.
However, AloSIM does have one unique advantage — when you purchase a Thailand eSIM, it includes a free international phone number. You can find more details about this feature directly on AloSIM’s official website.
| Destinations | Duration | Data Plans | Price (USD) |
|---|---|---|---|
| Thailand | 7 days | Total 1GB | $3.00 |
| Thailand | 30 days | Total 3GB | $6.00 |
| Thailand | 30 days | Total 5GB | $8.00 |
| Thailand | 30 days | Total 10GB | $16.00 |
| Thailand | 30 days | Total 20GB | $19.50 |
