Simbye eSIM Data Plans for Thailand

Simbye does not provide a truly unlimited data eSIM for Thailand. All plans that carry the word “Unlimited” in their name actually have a data cap of 50GB or 2GB per day, and once the cap is reached the speed is throttled to 1000kbps.

Travelers who need a large amount of high‑speed data can instead choose one of Simbye’s fixed‑data plans. For example, the 50GB 180‑day plan costs $44.99 USD, the 50GB 7‑day plan costs $19.99 USD, and the 50GB 15‑day plan costs $34.99 USD. These plans provide a generous data allowance without the speed reduction that applies to the “Unlimited” plans, making them a more cost‑effective option for most users.

Simbye provides eSIM plans for Thailand that include a local phone number and full telephony support. The country‑specific options are the Thailand Unlimited 7 days, 15 days and 30 days plans, each priced between $16.99 USD and $42.49 USD and offering validity from 7 days up to 30 days. All three plans feature a real Thai phone number with the dialing code +66, allowing inbound and outbound voice calls and inbound and outbound SMS. For users who need specific call or messaging features, it is recommended they verify the details directly with Simbye.

Simbye lists 12 single‑country data plans and 14 multi‑country data plans that cover Thailand. The plan portfolio spans a price range from approximately $2.54 to $50.99 and data caps from 1 GB up to 100 GB, with validity periods between 7 and 180 days. Buyers can choose between fixed data‑cap packages, which provide a set amount of data for the duration of the plan, and daily‑cap packages that reset each day offering a set amount of data per day. This range allows users to find a plan that fits both budget and usage expectations.
