Simsima eSIM Data Plans for Thailand

Simsima does not provide a truly unlimited data eSIM for Thailand. The plans that carry the name “Unlimited” actually give 3GB of high‑speed data per day and, once that daily limit is reached, the speed is throttled to 1000kbps.

Travelers who need more data can choose from Simsima’s fixed‑data plans. For example, a 100GB plan is available for 180 days, a 50GB plan for 90 days, and a 20GB plan for 30 days. All of these plans use the 5G network in Thailand and offer a larger total data allowance, which can be more cost‑effective for users who consume a lot of data.

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 offers a range of data plans for Thailand that includes 12 single‑country options and 4 multi‑country options. The provider supplies both fixed data‑cap plans, where customers receive a set amount of data over the validity period, and daily data‑cap plans that limit usage to a daily maximum. Across all plans, prices vary from about $1.50 to $178.50, while data caps range from 100 MB up to 100 GB, giving travelers a broad spectrum of choices depending on their needs and travel duration.
