eSIM for Thailand

What is important to know before choosing an eSIM for Thailand

• Local tourist SIM in Thailand is usually issued with a passport
  True/dtac explicitly states that the tourist SIM must be registered with a valid passport in accordance with NBTC requirements.

• eSIM for Thailand can be conveniently activated in advance
  AIS indicates that travelers from abroad can purchase a local eSIM online independently, and it is available for use immediately. This is exactly the scenario when internet access is needed right after landing, without searching for a service center.

• For Thailand, it is especially important to choose a plan based on the duration of the trip
  Local tourist packages often have a fixed duration: AIS offers options for 1, 5, 8, 15, and 30 days; True/dtac offers options for 8, 15, and 30 days, plus a separate data-only option for 10 days.

• After the tourist package expires, it may not always be possible to extend it simply by topping up
  True/dtac specifically states that the validity of the tourist SIM should not exceed 60 days, and after the expiration, it cannot be extended through a regular top-up — re-identification with a passport is required in-store or through support for continued service. For tourists, this is an important local feature: it is better to choose a plan based on the actual duration of the trip rather than expecting to "top up and continue using."

• 5G is available in Thailand, but it is not the main selection criterion
  In Thailand, tourist packages do indeed come with 5G, but access depends on coverage, the device, and the package itself; AIS clearly states that 5G may not work outside of coverage areas or if the package/device is not compatible. Therefore, on the Thailand page, it makes more sense to focus on data volume and validity period, while mentioning 5G as an additional benefit.
