AIS eSIM (2026)

Mobile carrier in Thailand

AIS offers eSIM to its customers in Thailand. But a local carrier eSIM usually needs local ID or residency — so for a short visit, a travel eSIM is faster and often cheaper: buy online, scan a QR code, and connect on arrival. Travel eSIMs for Thailand start at $5.00.

Does AIS offer eSIM?

Yes, AIS, one of Thailand's leading mobile network operators, has fully embraced eSIM technology and has been offering it to its customers for several years. As of 2026, eSIM is a standard offering for both new subscriptions and existing customers looking to convert their physical SIM cards. This means that whether you're a resident of Thailand or a long-term visitor with appropriate documentation, you can obtain an AIS eSIM for your compatible device.

How to get an AIS eSIM (for Thailand residents)

For residents of Thailand, acquiring an AIS eSIM is a straightforward process, typically requiring a visit to an AIS service center or flagship store. The process is similar for both prepaid and postpaid plans:

  • New Subscription: If you're signing up for a new AIS mobile plan, you can request an eSIM profile directly instead of a physical SIM card. The staff will guide you through the activation process, which usually involves scanning a QR code to download the eSIM profile to your device.
  • Converting Physical SIM: Existing AIS customers with a physical SIM card can typically convert it to an eSIM. This also requires a visit to an AIS shop, where a representative will assist with the conversion and provide the necessary QR code for your device.
  • Requirements: To obtain an AIS eSIM, you will need to provide valid identification. For Thai nationals, this is typically your Thai National ID card. For foreigners residing in Thailand, you will need your passport along with a valid visa (such as a work permit visa, long-stay visa, or student visa) and potentially proof of address. Your device must also be eSIM-compatible.
  • Activation: Once you receive the QR code, you'll scan it using your phone's settings (usually under 'Mobile Data' or 'Cellular Plan'). Your device needs to be connected to Wi-Fi during this initial setup. After successful installation, your AIS eSIM will be active and ready for use.

AIS eSIM for travellers and tourists

While AIS does offer eSIM, getting one directly from an AIS shop as a short-term tourist can be more cumbersome than necessary. Although it's technically possible to purchase a tourist SIM package (which might include an eSIM option) at an AIS store upon arrival, it often involves:

  • Physical Presence: You must visit an AIS shop at the airport or in a city, which takes time out of your travel schedule.
  • Documentation: You'll need to present your passport for registration, as required by Thai law for all SIM card activations.
  • Language Barriers: While major tourist areas have English-speaking staff, communication can sometimes be a challenge.
  • Limited Options: Tourist eSIMs directly from AIS might be tied to specific packages that may not offer the flexibility or data volume you need.

For these reasons, a dedicated travel eSIM from a global provider is often the preferred and more convenient option for most short-term visitors to Thailand. These travel eSIMs typically leverage the network of local carriers like AIS (or others like TrueMove H or Dtac) but are purchased and activated entirely online.

AIS vs a travel eSIM for Thailand

Choosing between an AIS eSIM directly from the carrier and a third-party travel eSIM depends largely on your specific needs and duration of stay.

AIS eSIM (Direct from AIS):

  • Pros: Full integration with the local network, access to local customer support, potential for better long-term rates for residents, and a local Thai phone number for calls and SMS.
  • Cons: Requires physical presence at an AIS shop, strict ID/residency requirements, potentially less convenient for short-term tourists due to registration processes and store visits.

Travel eSIM (Third-Party Providers like Airalo, Nomad, Holafly):

  • Pros: Unmatched convenience – purchase online before you travel, instant QR code delivery via email, activate upon arrival, no need to visit a physical store, no local ID registration hassle for the eSIM itself. Often data-focused, perfect for internet access, navigation, and messaging apps.
  • Cons: Typically data-only (or with very limited call/SMS features via VoIP apps), no local Thai phone number (unless specified by the provider), might be slightly more expensive for very long stays compared to a local long-term plan, and customer support is handled by the third-party provider, not AIS directly.

Conclusion: For residents and long-term visitors to Thailand, obtaining an AIS eSIM directly is a practical and cost-effective choice. However, for short-term tourists seeking immediate connectivity and maximum convenience without the hassle of store visits and local registration, a travel eSIM from a global provider is overwhelmingly the superior option. It allows you to land in Thailand with your internet already sorted, ready to connect from the moment you switch on your phone.
