Thailand eSIM

 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).

Yes, WhatsApp, FaceTime, and other video/voice calling apps work perfectly fine over mobile data and Wi-Fi throughout Thailand.

Thailand does not impose any restrictions on Voice over IP (VoIP) services, meaning you can freely use popular communication apps like WhatsApp, FaceTime, Line, Zoom, and Google Meet to make calls and video calls. As long as you have a stable internet connection, either via your eSIM's mobile data or a local Wi-Fi network, your calls will connect normally. An eSIM ensures you have reliable data coverage to support these applications by automatically connecting to the strongest available major network in Thailand. The exact network provider your eSIM connects to may vary depending on your specific plan, but you can expect consistent connectivity for all your communication needs.

 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.
