Simsima eSIM Data Plans for Thailand

Simsima does not offer a truly unlimited data eSIM for Thailand. All of its available plans for Thailand are fixed‑data plans. For example, the “100 GB – 180 days” plan gives 100GB of high‑speed data for 180 days, and the “50 GB – 30 days” plan provides 50GB for 30 days. The plans that carry the word “Unlimited” in their names actually allow 3 GB of high‑speed data per day; after reaching that daily limit the network speed drops to 1 Mbps. If a traveler needs larger, unrestricted data volumes, choosing a fixed‑data plan such as the 100‑GB or 50‑GB bundles may be more cost‑effective.

Simsima does not provide a Thailand eSIM that includes a phone number or SMS capability. Only data‑only plans are offered for travelers heading to Thailand.

Travelers can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection, but some destinations may block or restrict these services, so it is advisable to verify that the apps you rely on are accessible in Thailand before purchasing a plan.

Simsima provides a mix of single‑country and multi‑country data plans for Thailand, with 14 single‑country options and 21 multi‑country options available. The plans span a price range from about $1.50 to $178.48 and offer data caps between 100 MB and 100 GB. Some plans feature a daily data cap, limiting usage each day, while others offer a fixed data amount that can be used over the entire validity period. This variety allows travelers to choose a plan that best fits their data needs and budget.
