Simbye eSIM Data Plans for Thailand

Simbye does not offer a truly unlimited data eSIM for Thailand. All of the plans listed for Thailand have a data cap—either a fixed 50 GB allowance or 2 GB per day. For example, the Thailand 50GB 180Days plan provides 50 GB of high‑speed data for 180 days at $44.99 USD. Other “Unlimited” named plans, such as the Thailand Unlimited 7 Days with Real Thai Phone Number on DTAC 5G, are also capped at 50 GB; after the limit is reached the speed drops to 1000 kbps. Fixed data plans like the 50 GB 180‑day option are available and may be more cost‑effective for travelers who do not need a wide open data allowance.

Simbye offers Thailand eSIM plans with a real Thai phone number, enabling both inbound and outbound voice calls and inbound and outbound SMS messages. The plans are available for 7, 15, and 30 days, with data caps of 50 GB and prices ranging from $19.99 USD for the 7‑day option to $49.99 USD for the 30‑day option. The phone numbers use the local dialing code +66, so they are treated as domestic Thai numbers. All plans support communication in both directions for voice and SMS, and users should confirm specific requirements with Simbye before purchasing.

Simbye offers 12 single‑country data plans that cover Thailand alone and 11 multiple‑country plans that include Thailand as part of a broader network. The plans range in price from $3.00 to $60.00 and provide between 1 GB and 50 GB of data, with validity periods ranging from 7 to 180 days. Within the catalog there are both fixed data cap plans—where a set amount of data (such as 1 GB, 5 GB, 10 GB up to 50 GB) is available for the entire validity period—and daily data cap plans (3 of them), where a smaller amount of data is used on a day‑by‑day basis, offering users flexibility based on their usage habits.
