RoamGo eSIM Data Plans for Thailand

RoamGo does not provide a truly unlimited high‑speed data eSIM for Thailand. The plans that carry the “Unlimited” label give a fixed daily high‑speed allowance of 1GB/day or 2GB/day and then offer unlimited data at a reduced speed of 384kbps after the daily quota is used. This is not a high‑speed unlimited plan.

Travelers who need large amounts of high‑speed data can choose RoamGo’s fixed data plans, such as the Thailand 50GB 10Days, Thailand 50GB 30Days, or Thailand 50GB 180Days options. These plans provide 5G coverage in Thailand and have validity periods of 10, 30, or 180 days, respectively, and may be more cost‑effective for heavy data users.

RoamGo does not provide an eSIM plan with a phone number or SMS capability for Thailand; only data‑only plans are available. Travelers can use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for voice and messaging, but they should verify that those services are accessible in Thailand before purchasing, as some destinations may block or restrict specific apps or VoIP services.

RoamGo lists 72 single‑country packages for Thailand and 188 multi‑country options that include Thailand. Prices for Thai‑specific plans run from about $0.75 to $438.75, with data caps ranging from 500 MB to 50 GB. The catalog offers both fixed‑data plans, which provide a set amount of data for the entire validity period, and daily‑cap plans, which reset the data quota each day.
