Lifesaver for Thailand trip
I was nervous about connectivity but this worked flawlessly. Fast 4G in Bangkok and even decent speed in Chiang Mai. Price was way cheaper than my carrier roaming plan.

Traveller reviews for Thailand
1 verified reviewThailand eSIM plans at a glance
Wanderly lists 56 fixed-data Thailand plans, ranging from 1GB up to 50GB over 7 to 365 days. Prices start at $1.99, and the lowest cost per gigabyte is $0.24/GB on the 50GB 10-day plan.
Unlimited day-passes are also available from $1.99 per day, billed per day rather than per gigabyte. All 76 Thailand plans can be topped up without reinstalling the eSIM.
Every plan is data-only and installs from a QR code, so your home number stays active on its own line. Validity starts when the eSIM first connects to a network in Thailand, not at purchase, which means you can install before you fly.
🇹🇭 About eSIMs in Thailand
Thailand's two best carriers, AIS and TrueMove H, deliver excellent 4G and expanding 5G across every place a traveler actually goes — Bangkok, Chiang Mai, Phuket, Koh Samui, Krabi and Pai. Wanderly Thailand eSIM plans connect to one of these tier-1 networks, so you get strong signal on Sukhumvit Road, on longtail boats around Phi Phi, and even in the Chiang Mai hills.
Data burns fast in Thailand because you are Grab-ing everywhere, translating menus, and posting sunsets. A 7-day, 10 GB plan is comfortable for a first-timer; two-week island hoppers usually want 15–20 GB. Unlimited plans are worth it if you rely on Google Meet, Zoom or Netflix in the evenings.
The SIM booths at Suvarnabhumi and Don Mueang work fine but are marked up. An eSIM installed at home lets you skip the queue entirely and be on Google Maps the moment your flight lands.
How to activate your eSIM in Thailand
- 1Install at homeScan the QR while you still have hotel or home Wi-Fi. You do not have to activate yet — the timer starts when data is first used.
- 2Turn on after landingEnable the Thailand eSIM as your primary data line, keep your home SIM for iMessage. Turn on Data Roaming (required for eSIMs).
- 3Grab and LineInstall the Grab app for taxis and Line for restaurant bookings and guesthouses — both need data to sign up.
- 4Hotspot for travel buddiesWanderly Thailand plans allow tethering, so your partner or a group of friends can share one plan on longer trips.
