Set how many days you will be in Thailand and how much data you expect to use. The finder checks every plan listed by the 13 providers on our board and shows the ones that cover your whole trip, cheapest first.
Find the cheapest plan for your trip
Prices as each provider listed them on October 27, 2026; sale prices change, so confirm at checkout. A rule of thumb, not a measurement of your usage.
How the finder works
- A plan is shown only if its validity is at least as long as your trip, so a 7-day plan never appears for a 10-day stay.
- A fixed plan is shown only if its data is at least the size you pick. Unlimited passes appear when you switch them on or choose unlimited only.
- Many unlimited passes cap full-speed data per day, then slow down. The cap is printed under each pass; compare it, not only the price.
- Prices are what each provider listed on its own Thailand page on October 27, 2026. Yesim and Simbye price in euros, so they are listed apart and not converted.
- The days-a-trip figure divides the plan price by your trip length, not by the plan length.
Trips longer than a month
Past 30 days the list gets short. TonMobile lists 50 GB for 90 days at $45.00 and 100 GB for 180 days at $89.00; every other plan in the finder ends at 30 days. Holafly says it sells unlimited plans up to 90 days, but the prices we could read on its page stop at 30 days, so the finder only shows what is listed.
Before you buy
- Check that your phone supports eSIM and is not carrier-locked; the setup guide shows how.
- Not sure how much data you need? The data guide maps common trips to plan sizes.
- Compare what else matters, such as named networks and hotspot rules, on the provider board.
Plan finder questions
Which plans does the finder include?
Every fixed and unlimited Thailand plan with a price that we could read on the provider's own page on October 27, 2026, from 13 providers. Plans without a visible price, such as aloSIM's day-based tiers with no stated data, are left out.
Why are some prices in euros?
Yesim and Simbye show euro prices on their Thailand pages. We keep them as listed instead of converting at a rate that changes daily.
Is the cheapest plan always the best one?
Not always. Check the validity start, the daily cap on unlimited passes and whether the provider names the Thai network. The provider board scores those points.
