Astaroam eSIM Data Plans for Thailand

Astaroam does not offer truly unlimited data eSIM plans for Thailand. The plans that carry the label “Unlimited” actually provide 3 GB of high‑speed data each day and after that limit the speed to 1000 kbps. Because of this daily cap, these plans are not unlimited in the sense of providing high‑speed data without limits.

For travelers who require larger or truly unlimited data, Astaroam provides fixed‑data options instead. A 20 GB plan for 30 days or a 50 GB plan for 90 days are examples of the available fixed‑data plans in Thailand. Choosing a fixed‑data plan can be a more cost‑effective solution unless the user is an extremely heavy data consumer.

Astaroam does not offer a Thailand eSIM that includes a phone number or SMS capability; the provider sells only data‑only plans for Thailand. Travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for voice and messaging, but because some destinations block or restrict certain apps or VoIP services, users should confirm that the VoIP services they need are accessible in Thailand before purchasing a plan.

Astaroam offers 15 single‑country data plans and 32 multi‑country plans for travelers in Thailand. The plans range in price from $1.32 to $48.75 and provide data caps between 500 MB and 50 GB across validity periods of 3 to 90 days. Among them, 13 plans are daily data cap plans, which allocate a fixed amount of data each day, while 34 plans are fixed data cap plans that provide a set total data allowance for the plan’s duration. Optional features on some plans include tethering and a reduced‑speed threshold.
