Astaroam eSIM Data Plans for Thailand

Astaroam does not provide an truly unlimited data eSIM for Thailand. The plans that carry the “Unlimited” name give a data allowance of 3GB per day; once the daily amount is used, the speed is throttled to 1000kbps.

Customers who need a higher data volume can choose Astaroam’s fixed‑data plans instead, such as the 50GB plan valid for 90 days at $33.57 USD or the 20GB plan valid for 30 days at $10.38 USD. These options give a larger data pool without the daily limit and may be more economical for heavier data users.

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.
