2 Best Thai Sim Card 2025 in the United States

The AIS Thailand Traveller SIM Card offers 15 GB of non-stop internet for 8 days, making it ideal for tourists visiting Thailand. One of its strongest points is the generous data allowance, which should be sufficient for most users' internet needs. However, after 15 GB, the speed drops to 384 kbps, which might impact those relying heavily on high-speed internet.

The SIM also includes unlimited data usage on popular social apps like Facebook, Instagram, and WhatsApp, but this is restricted to app usage on your phone only and not when sharing internet with other devices or using browsers. Activation is simple and hassle-free; just insert the SIM into an unlocked phone upon arrival in Thailand, turn on mobile data, and it activates automatically. This ease of activation is a significant advantage for travelers who want to start using their phones immediately.

On the downside, the SIM does not support making calls, which could be a drawback for users who need voice communication. Additionally, it does not offer roaming services outside Thailand, limiting its use to within the country. The physical nature of the SIM means it cannot be converted to an eSIM, which might be a limitation for some modern phone users. In summary, the AIS Thailand Traveller SIM Card is best suited for tourists needing reliable data usage within Thailand, especially for social media and internet browsing, but it may not be ideal for those requiring call services or international roaming.

This 10-day Thailand eSIM offers 50 GB of high-speed 4G data and 100 minutes of local calls, which is quite generous for travelers needing reliable internet and calling without a physical SIM card. Its coverage is stable and fast thanks to LTE technology, so you should get good signal strength around Thailand. Activation requires registering online at least two days before use, which could be a bit inconvenient if you decide last-minute. After activation, you'll receive a QR code to set up the eSIM easily on compatible and unlocked devices.

The validity of the plan is fixed at 10 days, ideal for short trips but not flexible for longer stays. The product mentions 24/7 WhatsApp customer support. This eSIM is well suited for visitors looking for hassle-free, high-data mobile access during a brief visit to Thailand, especially if you prefer digital convenience over physical SIM cards. Just keep in mind to prepare in advance for activation and confirm your device compatibility.
