Frequently Asked Questions
Does Firsty offer unlimited data eSIM for Thailand?
Firsty offers an unlimited data eSIM plan for Thailand called Firsty Free, which provides unlimited data for 1 day at a price of $0.00 USD. The plan includes advertising and a maximum speed of 256 kbps, with the light‑speed allowance subject to the provider’s fair‑usage policy.
Because the unlimited plan is capped at 256 kbps and may be thrott after heavy use, travelers who want to confirm whether the full data allowance can be consumed at higher speed should contact Firsty directly to inquire about the FUP limits and typical data volumes that remain available at normal speed.
Does Firsty offer Thailand eSIM with phone number and SMS?
Firsty does not offer any eSIM plans for Thailand that include a phone number or SMS capability. Only data‑only eSIMs are available from Firsty for travelers in Thailand. Over the data connection, popular VoIP services such as WhatsApp, Telegram, and iMessage can be used for voice calls and messaging.
How many data plans does Firsty offer for Thailand?
Firsty provides 16 single‑country plans that cover Thailand and an additional multi‑country option that includes Thailand as part of its broader coverage.
The plans are split mainly into two types: fixed‑data caps and daily‑data‑cap plans. Fixed‑data plans offer a set amount of data that does not reset each day, while daily‑data‑cap plans replenish a set data allowance each day for the life of the validity period.
Typical first‑tier listings show prices ranging from free to about $68.98, with data caps starting around 1.5 GB and extending to unlimited options depending on the chosen plan. Validity periods vary from a single day up to 30 days, giving travelers flexibility between short‑term day‑plans and longer‑term stays.
