Frequently Asked Questions
Does Firsty offer unlimited data eSIM for South Korea?
Firsty offers an unlimited data eSIM for South Korea with its first‑time user plan, the Firsty Free plan. This plan provides unlimited data for 1 day at no cost, contains advertising, has a maximum speed of 256 kbps, and may throttle speeds after heavy use, as governed by a fair‑usage policy. If you anticipate intensive data use or need higher speeds, you should contact Firsty to confirm whether a different plan or a higher‑speed unlimited option applies and what the typical data allowance at normal speed will be.
Does Firsty offer South Korea eSIM with phone number and SMS?
Firsty does not provide an eSIM for South Korea that includes a local phone number or SMS capability. Only data‑only eSIM plans are available from Firsty for this destination. Travelers can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection to make calls and send messages without a traditional phone number or SMS service.
How many data plans does Firsty offer for South Korea?
Firsty offers 16 single‑country data plans and 1 multi‑country plan that cover South Korea. The single‑country options include both daily data cap plans, which reset each day, and fixed data cap plans that provide a set amount of data for the entire validity period. Prices for these plans range from free to about $105 USD, with data caps from 1.5 GB up to unlimited. Validity periods vary between one and thirty days. The multi‑country plan follows the same pricing and data cap spectrum but extends coverage to additional destinations.
