Frequently Asked Questions
Does Firsty offer unlimited data eSIM for Thailand?
Firsty does not provide any unlimited‑data eSIM plans for Thailand. All of Firsty’s plans in Thailand are fixed‑data packages with 5GB per day, such as the 5‑day plan costing $13.16 USD and the 10‑day plan costing $25.13 USD.
Choosing a fixed‑data plan can be more cost‑effective for most travelers, unless you are an extremely heavy data consumer who would otherwise exceed the daily allowance.
Does Firsty offer Thailand eSIM with phone number and SMS?
Firsty does not provide an eSIM for Thailand that includes a local phone number or SMS capability. The provider offers only data‑only plans for travelers. Travelers can still use VoIP services such as WhatsApp, Telegram, or iMessage via the data connection for voice and messaging.
How many data plans does Firsty offer for Thailand?
Firsty offers 16 single‑country data plans for Thailand. No multi‑country plans are available from this provider. The plans come in two formats: 14 daily‑cap options that limit the amount of data you can use each day, and 2 fixed‑cap options that provide a set amount of data for the full validity period. Prices run from approximately $1.79 to $71.79 and data caps range from 1.5 GB to 5 GB, giving travelers a broad spectrum of choices for short‑term connectivity.
