ETravelSim eSIM Data Plans for Thailand

ETravelSim does not offer a truly unlimited data eSIM for Thailand. The plans that carry “Unlimited” in their title actually provide a fixed high‑speed data allowance, the largest of which is 100 GB for 7 days. After the 100 GB limit is reached, no additional data is supplied, and unless a reduced speed figure is stated (it is not in this case) the connection simply stops providing high‑speed data.

If a traveler wants a substantial amount of data without the uncertainty of unlimited usage, ETravelSim offers several fixed‑data alternatives. For example, the “Thailand eSIM (ZF) 80 GB – 10 days” plan gives 80 GB of high‑speed data for ten days, and the “Thailand eSIM (ZF) 50 GB – 10 days” plan offers 50 GB for the same period. These fixed plans can be more cost‑effective than a plan that advertises unlimited usage but actually caps data.

ETravelSim does not provide an eSIM for Thailand that includes a local phone number or SMS capability. All Thailand eSIM plans offered by ETravelSim are data‑only, so no inbound or outbound voice calls or SMS messages can be sent or received directly using a cell number from the carrier.

Travelers who need to make calls or send text messages can use VoIP applications such as WhatsApp, Telegram, or iMessage, which operate over the data connection and do not require a dedicated phone number or SMS service.

ETravelSim currently offers three single‑country data plans and ten multi‑country plans for Thailand. The plans range in price from $8.49 to $109.99, and data caps vary from 4 GB to 100 GB, with validity periods between 7 and 365 days.
