Simbye eSIM Data Plans for Thailand

Simbye does not offer a truly unlimited data eSIM for Thailand. All of its plans for Thailand have a hard data cap, after which the speed is throttled. For example, the “Thailand Unlimited 7 Days with Real Thai Phone Number on DTAC 5G” gives 50 GB of high‑speed 5G data before reducing the speed to 1 Mbps. Other similar plans provide 2 GB per day for the stated validity period, also with a reduced speed after the limit is reached. These fixed‑data plans can be a cost‑effective choice for most travelers unless they need unlimited high‑speed data.

Simbye offers several Thailand‑based eSIM plans that include a local phone number and full telephony support. The “Thailand Unlimited” plans provide a real Thai phone number with dialing code +66, allow inbound and outbound voice calls, and support inbound and outbound SMS. Prices range from $19.99 for a 7‑day plan to $49.99 for a 30‑day plan, each with a 50GB data allowance on DTAC 5G and optional tethering.

Simbye also sells international “Worldwide Orange Holiday” plans with a French phone number (dialing code +33). These plans are available for use in Thailand, offering inbound and outbound voice calls and SMS, with data caps of 20GB, 50GB, or 100GB for 30 days. Users interested in a specific feature set should confirm the details directly with Simbye before purchase.

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.
