Airalo Thailand eSIM prices 2026
Airalo offers Thailand fixed-data plans with 3-, 7-, 15- and 30-day validity options, plus unlimited plans from 3 to 30 days. Compare the window you need: the shorter 5 GB plans cost less than the 30-day version.

Holafly Thailand eSIM prices 2026
Holafly only sells unlimited plans — no fixed data options. Their Thailand lineup spans six tiers from 3 to 30 days, with a per-day rate that drops sharply on longer plans: $3.97/day for 3 days, $3.93/day for 7 days, and $2.46/day for 30 days. That makes Holafly more competitive for month-long stays than for short trips.
Holafly unlimited plans
| Validity | Price (USD) | Price per day | FUP |
|---|---|---|---|
| 3 days | $11.90 | $3.97 | Not disclosed |
| 5 days | $20.50 | $4.10 | Not disclosed |
| 7 days | $27.50 | $3.93 | Not disclosed |
| 10 days | $36.50 | $3.65 | Not disclosed |
| 15 days | $50.50 | $3.37 | Not disclosed |
| 30 days | $73.90 | $2.46 | Not disclosed |
Worth knowing: On shorter trips Holafly is the most expensive option in this comparison — a 7-day plan costs $27.50, versus $9.99 for a 10 GB fixed plan from Travelsim Asia or $15 for Nomad's 10-day unlimited. On 30-day plans the per-day rate drops to $2.46, which is closer to competitive, but still totals $73.90 — more than triple the cost of a fixed 20 GB alternative that covers the same trip length comfortably for most travelers. Holafly also doesn't disclose their FUP threshold for Thailand.
Networks: TrueMove H and dtac, both brands on True's combined network. App optional — manageable via customer panel.
Nomad Thailand eSIM prices 2026
Nomad’s ten-day unlimited plan costs $15 on sale. Its 50 GB / ten-day fixed plan costs $15. Check the high-speed limit on unlimited plans and the validity window on fixed plans before choosing.

Networks: Saily does not publicly specify which Thai carrier they use. App required. Their 5 GB / 30-day plan costs $7.99, ten cents above Travelsim Asia’s $7.89. Saily's "unlimited" plans are technically unlimited in volume but throttle to slower speeds after 5 GB of high-speed data per day — which makes them poor value compared to Nomad's unlimited (cheaper) or fixed plans of equivalent volume.
Ubigi Thailand eSIM prices 2026
Ubigi offers one-off fixed and unlimited plans alongside subscriptions. Its 10 GB / seven-day plan costs $9, while 10 GB / 30 days costs $11. The unlimited 30-day plan includes 60 GB at full speed, followed by 2 Mbps for the rest of the plan.

Our 1 GB and 3 GB plans lead those sizes here, and our 5 GB and 10 GB plans lead their 30-day tiers.

Travelsim Asia leads four rows of this one-off comparison: 1 GB ($1.99), 3 GB ($4.99), 5 GB / 30 days ($7.89) and 10 GB / 30 days ($9.99). Airalo costs $1.99 less at 20 GB / 30 days; Nomad leads the 50 GB / ten-day tier at $15. Our 50 GB / 180-day plan costs $54.99, with no matching one-off validity window among the supplied alternatives. For seven-day trips, Airalo’s 5 GB at $7 and Ubigi’s 10 GB at $9 are cheaper than our 30-day plans.
Which Thailand eSIM gives the best value?
There's no single best answer — it depends on your trip length, usage, and priorities. Here's a straightforward breakdown:
- Best for short stopovers or budget travelers (1–3 GB): Travelsim Asia — cheapest 1 GB in this comparison at $1.99 and cheapest 3 GB at $4.99 with 15 days validity. Saily is next at 1 GB for $2.99 / seven days; Ubigi is next at 3 GB for $5 / 15 days. For a full 30 days at 3 GB, Saily costs $5.99.
- Best for standard trips (5 GB, 30 days): Travelsim Asia — $7.89, the cheapest 5 GB / 30-day plan in this comparison, with no app and no account. Saily is $7.99 and Airalo $8.00.
- Best for standard trips (10 GB, 30 days): Travelsim Asia — $9.99 is the cheapest 10 GB / 30-day plan in this comparison. Nomad is a cent behind at $10.00; Saily $10.99; Airalo $11.00; Ubigi $11.00. Planning a full month? See our dedicated best eSIM for Thailand 1 month guide for plan recommendations specifically for 30-day stays.
- Best for 20 GB (30 days): Airalo — $18.00. Travelsim Asia and Saily are tied at $19.99.
- Best for unlimited data: Nomad — $15 for 10 days (on sale) has the lowest total price among the ten-day unlimited plans in this comparison, and they disclose their throttling threshold. Holafly's 30-day $73.90 plan works out to $2.46/day compared with $18 for Airalo’s fixed 20 GB over the same period. These offer different amounts of high-speed data.
- Best for heavy short trips (50 GB / 10 days): Nomad at $15 / 10 days is excellent value at $0.30/GB, with Travelsim Asia's $15.99 / 10-day 50 GB plan the next option ; Airalo’s $27.50 option lasts 30 days rather than ten.
- Best for long stays and repeat visitors (1–6 months): Travelsim Asia’s 50 GB / 180-day pack costs $54.99. The 50 GB is one total allowance, usable across the full validity period. Compare that with a subscription’s monthly allocation if you make repeated trips.
- Best for frequent Thailand visitors (year-round): compare Ubigi’s subscription options with a one-off long-validity plan. Check the monthly allowance, renewal price and cancellation terms. Subscription prices are outside the 10 October one-off comparison.
- Among the worst value for short trips: Holafly — at $3.97/day on the 3-day plan and $3.93/day on the 7-day plan, a week of unlimited data costs $27.50, nearly three times the cost of Travelsim Asia's 10 GB fixed plan at $9.99.
Hidden costs to watch out for
The headline price rarely tells the full story. Here are the things that trip people up when choosing a Thailand eSIM.
- Throttling on unlimited plans. An unlimited allowance does not promise unlimited speed. Saily lists 5 GB a day before throttling; Nomad’s plan has a daily high-speed cap. Ubigi’s $49 / 30-day plan includes 60 GB at full speed, then 2 Mbps for the remainder. Holafly’s exact threshold is not stated in this comparison. Fixed-data plans avoid a daily fair-use clock, but actual speed still depends on signal, congestion and the plan.
- Validity mismatch. Always check validity alongside price. Airalo's 1 GB plan lasts only 3 days — fine for a Bangkok layover, frustrating for a longer trip. Travelsim Asia's equivalent lasts 7 days for less money. At the 3 GB tier, Saily's $5.99 plan lasts 30 days, but Travelsim's $4.99 plan at 15 days is cheaper if you don't need the full month.
- App requirements. Providers differ in purchase, installation and management steps; an available app does not mean it is required for installation. Download the instructions while you have Wi-Fi. Travelsim Asia delivers by email — installs from any browser, no account needed. If you're continuing to Japan after Thailand, the same setup process applies — see our Japan eSIM install guide.
- Sale prices. Nomad's unlimited 10-day plan at $15 is a sale price. Before making a decision based on it, verify it's still active. Competitor comparison: 23 October 2026; confirm the sale price before purchase.
Unlimited vs fixed: which is actually better for Thailand?
Thailand is a destination where this question comes up often — and the answer is more nuanced than for most Asian destinations. Usage patterns vary a lot depending on where you are.
Fixed or unlimited?
| Fixed data plan | Unlimited plan | |
|---|---|---|
| Speed | No daily cap; actual network speed varies | High-speed allowance, then reduced speed |
| Predictability | Know exactly what you're getting | Depends on daily usage patterns |
| Price | Lower for typical users | Higher — you pay for peace of mind |
| Best for | Most travelers | Heavy streamers, hotspot users |
| Runs out? | Yes; top-ups depend on the plan | No — but may throttle badly |
For most Thailand travelers, a fixed 5–10 GB plan is the sweet spot. Most islands and popular cities have excellent WiFi at guesthouses, cafés, and restaurants — so you're often only using mobile data for maps, Grab, and messaging while out. If you're island-hopping without reliable WiFi access, or working remotely, 10–20 GB fixed is more practical than unlimited. Unlimited plans in Thailand rarely justify the cost premium except for very heavy streamers. If you're traveling as a group and need to connect multiple devices, it's worth reading our eSIM vs Pocket WiFi breakdown — the same logic applies in Thailand.
How much data do you actually need for Thailand?
For a lighter trip, start with 5 GB for a week in Thailand and consider 10 GB for two weeks, using WiFi for heavier tasks. What pushes it higher is island-hopping rather than city time: moving between Samui and Krabi means more navigation and less of the guesthouse and cafe WiFi that covers most of your heavy use in Bangkok or Chiang Mai. Our Thailand data guide breaks that down app by app, and for stays of a month or more see our best eSIM for Thailand 1 month guide.
