Simsima for Thailand FAQ
Does Simsima offer unlimited data eSIM for Thailand?
Simsima does not provide a truly unlimited high‑speed data eSIM for Thailand. The plans that carry the word “Unlimited” in their name actually offer 3 GB per day; after that limit the speed drops to 1000 kbps. If a traveler needs more data without daily restrictions, simsima offers several fixed data plans. For example, a 100 GB plan is valid for 180 days and costs $84.53 USD, while a 50 GB‑30‑day plan costs $38.90 USD. A 20 GB‑30‑day plan is also available for $14.20 USD. These fixed‑data options can be more cost‑effective for heavy data users.
Does Simsima offer Thailand eSIM with phone number and SMS?
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.
How many data plans does Simsima offer for Thailand?
Simsima lists 12 single‑country plans and 19 multi‑country plans for Thailand. The plans cover a price range of roughly $0.40 to $84.53 and offer data from 100 MB to 100 GB over validity periods of 5 to 180 days. Some options use a daily data cap that resets each day, while others provide a fixed data allowance that applies for the entire validity period.
