Tip: if your current phone doesn't support eSIM but you travel often, an unlocked, mid-range eSIM-capable phone (e.g., Pixel 7a, iPhone SE 3, Samsung Galaxy A55) makes an excellent secondary travel device , pair it with a Cellesim plan and you have a full mobile internet kit for any destination.
It's simple! We will email you a QR code immediately after purchase. Scan this QR code in your phone's settings before you fly (or by using the free Wi-Fi at Bangkok (BKK) / Phuket (HKT) airport). You'll be connected the moment you land.
These plans are typically data-only, which means they do not include a local Thai phone number. You can continue to use your existing number for apps like WhatsApp, Telegram, or iMessage, which all work perfectly over the eSIM data (VoIP).
Yes. Thailand has an excellent 4G/5G infrastructure, especially in tourist areas. You can expect a reliable, high-speed connection whether you are in the temples of Bangkok, on the beaches of Phuket or Koh Samui, or in the mountains of Chiang Mai.
An eSIM is much more convenient. You skip the long SIM card queues at the airport. You also avoid the mandatory passport registration and paperwork required for physical SIM cards in Thailand, which can be time-consuming. With an eSIM, you are connected instantly.
If you reach your data limit, your connection will simply stop. You will never be charged extra fees or unexpected roaming charges. If you need more data, you can easily purchase a new plan from our website to "top-up".
It depends on your trip. For a short trip to Bangkok (3-5 days) using maps and social media, a 3GB or 5GB plan is often perfect. However, if you are on a long backpacking trip, uploading videos, or island hopping, one of our 16 unlimited plans offers the best value and peace of mind.
These plans are typically data-only, which means they do not include a local Thai phone number. You can continue to use your existing number for apps like WhatsApp, Telegram, or iMessage, which all work perfectly over the eSIM data (VoIP).
This specific plan is valid only within Thailand. This is the most important question for backpackers. If you are on the "Banana Pancake Trail" and cross the border into Cambodia (for Angkor Wat) or Laos (Vientiane), your connection will stop. For a seamless multi-country journey, we highly recommend our Asia Regional eSIM, which covers Thailand, Vietnam, Cambodia, and more with one single plan.
Yes, absolutely. Our eSIM connects to premium networks that provide excellent 4G/LTE coverage not just in Bangkok and Chiang Mai, but also on all major islands like Phuket, Koh Samui, Koh Phangan (for the Full Moon Party), and Koh Phi Phi. You will have a strong signal on the main beaches and in the towns.
Yes, 100%. Buying a physical "Tourist SIM" at Bangkok (BKK) or Phuket (HKT) airport is cheap but often involves long queues, especially after a big flight lands. It also requires a mandatory passport registration process. Our eSIM is 100% digital, requires no ID registration, and can be installed before you fly. You will be connected the moment you land, ready to use Grab.
To give you the best speed and coverage, our eSIM connects to Thailand’s premium Tier-1 networks, typically AIS or DTAC. AIS is widely regarded as the #1 provider with the fastest speeds and the most extensive 4G/5G coverage, especially on the islands and in rural areas.
Yes, absolutely. Grab is the essential "super-app" in Thailand (Uber is not available) for booking ride-hailing (cars and motorbikes) and food delivery. Our eSIM provides fast, low-latency data, which is crucial for ordering a Grab from the airport, tracking your driver in real-time, and using Google Maps to navigate.
Most modern phones do, but you must check our specific list here: eSIM Compatible Devices to be 100% sure before purchasing.
