Astaroam eSIM Data Plans for Thailand

Astaroam does not provide a true unlimited‑data eSIM for Thailand. The plans that carry “Unlimited” in their name actually offer a daily data allowance—5GB per day or 3GB per day—after which the speed is throttled to 1000kbps. For travelers who need a larger, non‑throttled data budget, Astaroam offers fixed data plans such as 50GB for 90 days at $33.55 USD or 20GB for 30 days at $10.67 USD. These fixed‑data options can be more cost effective for most users compared to the daily‑limit plans.

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 lists 14 single‑country plans that cover Thailand and an additional 32 multi‑country plans that also include Thailand in their coverage.
The available plans vary in cost from about $1.33 to $49.09 and in data limits from 500 MB up to 50 GB. Some plans are fixed‑cap packages that provide a set amount of data for the entire validity period, while other plans are daily‑cap packages that give a specified amount of data each day. Most of the plans allow tethering, although some may impose a temporary speed reduction to 1000 kbps.
