OthersBangkok’s traffic, Phuket’s beaches, Chiang Mai’s temples and the islands of the Gulf — a Thailand eSIM keeps your phone online across all of it without a roaming bundle from home or a queue at a counter in Suvarnabhumi. Buy a prepaid eSIM for Thailand online, install it over Wi-Fi before you fly, and your phone joins a Thai network automatically on arrival. Your own number and WhatsApp keep working on your primary SIM.
GlobaleSIM’s Thailand plan runs on AIS (Advanced Wireless Network), Thailand’s largest mobile operator, with 4G LTE and 5G in Bangkok, Chiang Mai, Pattaya, Phuket, Krabi and Hua Hin and reliable 4G in provincial towns, on the main highways and across the popular islands — Koh Samui, Koh Phangan, Koh Tao, Koh Lanta and Koh Phi Phi. AIS’s footprint extends well into the north around Pai and the Golden Triangle and along the Andaman coast; on remote beaches and in national parks expect weaker signal, as on any Thai network.
Plans start from $4 for 1GB, and Thailand is one of the destinations where GlobaleSIM offers a 50GB plan for long stays, digital nomads and heavy streaming. Sizes are 1GB, 2GB, 3GB, 5GB, 10GB, 20GB and 50GB. Validity for Thailand: 1GB is valid for 7 days, 2GB for 15 days, and every plan from 3GB upward for 30 days. Two weeks of beaches and cities with Grab rides, maps, translation and social media typically uses 5–10GB; a month in Chiang Mai working remotely or a family sharing a hotspot should pick 20GB or 50GB. Validity starts only when your phone first connects to a Thai network, so installing before departure is free.
Add voice minutes (+100, +200 or +300) to your Thailand data plan and you receive a dedicated international phone number for calls and SMS — for hotel and dive-shop bookings, ferry and minibus operators, restaurant reservations and verification codes. Voice service works over your eSIM data or Wi-Fi, and data-only travellers keep WhatsApp, LINE and iMessage on their existing number.
Grab for taxis and food delivery, BTS and MRT navigation in Bangkok, ferry and bus bookings between islands, translation for menus and market haggling, and mobile payments that are increasingly QR-based — a working connection is the backbone of a Thai trip. Café and hotel Wi-Fi is widely available but slow on islands and unusable on the move. Continuing to Vietnam, Malaysia, Singapore, Cambodia or Indonesia? The South East Asia regional plan covers Thailand and its neighbours on a single eSIM with automatic switching.
AIS network coverage, transparent one-time pricing with no roaming surprises, plans up to 50GB, hotspot support, the option of a real phone number, and human support around the clock. Compatible with any carrier-unlocked eSIM device, including iPhone 11 and later, Samsung Galaxy S20 and later, and Google Pixel.
