Frequently asked questions

How do I know if my phone is compatible with a Thailand eSIM?

Most unlocked smartphones released after 2018, including iPhone XS and newer, Samsung Galaxy S20 and up, and Google Pixel 3 onwards, support eSIM technology. Your device must also be carrier-unlocked to connect to local Thai networks. You can verify compatibility by checking your phone's settings for an EID number.

How much data do I need for my trip to Thailand?

For standard travel activities like using Google Maps, messaging, and taxi apps, 1 GB to 2 GB per day is typically sufficient. If you stream video, work remotely, or upload heavy content to Instagram, opt for an unlimited plan or at least 20 GB for a two-week vacation. Thailand features fast 5G networks in major tourist areas, which can consume data quickly if unmonitored.

When is the best time to install my Thailand eSIM?

You should install the eSIM right before your flight while connected to a stable Wi-Fi network at home or the airport. Keep the eSIM line turned off until you physically arrive at your destination in Thailand. Upon landing, turn on the eSIM line and enable Data Roaming to automatically connect to a local network.

Will WhatsApp, Instagram, and iMessage still work in Thailand?
Yes

all your apps, including WhatsApp, Instagram, iMessage, and Grab, will function normally without any extra configuration. WhatsApp and iMessage will automatically retain your primary home phone number for contacts and chats. The eSIM simply provides the mobile data connection required to keep these services online.

Does the Thailand eSIM include a local phone number?

Some Thailand eSIMs are data-only, while prepaid travel eSIMs from major local carriers like AIS or DTAC include a local (+66) phone number with calls and SMS. If you need a local number to register for local apps or call Thai businesses, choose a plan that specifies phone call credits. Data-only plans still allow internet calling through apps like WhatsApp or Line.

What should I do if my eSIM does not connect upon arrival in Thailand?

First, verify that the eSIM line is enabled and Data Roaming is toggled on for that specific profile in your device settings. Next, restart your phone to force a reconnection to local partner networks like AIS or TrueMove. If issues persist, verify that your APN settings match the setup instructions provided with your purchase.

How does a Thailand eSIM price compare to traditional international roaming?

Using a Thailand eSIM is significantly cheaper than traditional carrier roaming, which often costs $10 to $15 per day from home providers. Prepaid Thailand eSIM plans typically offer high-speed 5G data starting at just a few dollars for several days. This allows you to avoid unexpected pay-as-you-go bill shocks while enjoying local network rates.
