SimSmash does not provide a truly unlimited highspeed data eSIM for Thailand. All plans that use the word “Unlimited” in their name actually have a fixed data allowance—ranging from 490 MB to 10 GB for a single day—after which the speed is throttled.
Customers who need higher data volumes can choose from SimSmash’s fixed‑data offerings instead. For example, a 50 GB plan is available for 30 days at $34.49 USD and a 20 GB plan for 30 days costs $9.49 USD. These plans provide a larger data budget and are often more cost‑effective for regular travelers than the daily “unlimited” names.
SimSmash does not provide Thailand eSIM plans that include a local phone number or SMS capability. Only data‑only eSIMs are offered for Thailand. Travelers can still communicate and make calls using internet‑based messaging applications such as WhatsApp, Telegram, or iMessage, which work over the data connection without requiring a traditional phone number or SMS service.
SimSmash offers 13 single‑country data plans for Thailand and 18 multi‑country plans that include Thailand. The plans vary in price from roughly $0.79 to $94.99 and in data allowance from about 490 MB up to 50 GB, with some plans permitting tethering.
