Thailand eSIM tips
- Install before you fly and switch data to it after landing. Each day counts from when it connects in Thailand. Activate by the date shown at checkout.
- About 1.5 GB a day covers maps, messaging and social. Pick Unlimited for video calls or hotspot use.
- Best Thailand roams on AIS and dtac, and can be topped up. Thailand Special Unlimited runs on TrueMove H at 10 Mbps.
- Both plans are data only, with no Thai phone number. Calls and messages work over apps such as WhatsApp and LINE.

Thailand eSIM questions
Which network do these eSIMs use in Thailand?
Best Thailand roams on AIS and dtac and can connect to either. Thailand Special Unlimited runs on TrueMove H. All three are Thailand's main networks with 5G in cities; on remote islands and in the mountains, signal can be weaker on any of them.
Do I get a Thai phone number?
No. Both plans are data only. Calls and messages work over apps such as WhatsApp, LINE and FaceTime, and ride-hailing apps work on data. Keep your home SIM switched on if you need SMS codes from your bank.
When should I install it, and when does it start?
Install it before you fly, on your home Wi-Fi, and switch mobile data to it after landing. The plan starts when it connects in Thailand, and a day is 24 hours from first use. If you install it after arriving, it starts right away.
Can I add more data?
Best Thailand can be topped up without a new eSIM. Thailand Special Unlimited cannot, so pick enough days up front. You have 60 days from purchase to activate either plan.
Is there a discount?
