TailSim for South Korea FAQ

Does TailSim offer unlimited data eSIM for South Korea?

TailSim does not provide a true unlimited data eSIM for South Korea. The plans that carry “Unlimited’’ in their name actually give 1 GB per day and reduce the speed to 512 kbps once that daily limit is reached, which is not the same as unlimited high‑speed data.

Instead, TailSim offers fixed‑data plans that allow substantial data usage over a set period. For example, the 50 GB plan for 30 days costs $49.99 and the 20 GB plan for 30 days costs $19.99. These high‑allowance options give travelers large amounts of data without the speed reduction that characterizes the “Unlimited’’ name.

Does TailSim offer South Korea eSIM with phone number and SMS?

TailSim does not offer an eSIM for South Korea that includes a phone number or SMS capability. All of the South Korea eSIMs available from TailSim are data‑only plans. Travelers can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging. Users should confirm that these apps are accessible in South Korea before purchasing, as some destinations may restrict certain services.

How many data plans does TailSim offer for South Korea?

TailSim offers a total of 24 data plans for travellers visiting South Korea, split into 6 single‑country plans and 18 multi‑country plans. The plans range in price from about $3.99 to $81.99 and provide data caps from 1 GB up to 50 GB. Among them, some plans deliver a fixed amount of data for the entire validity period, while others are structured as daily data caps that reset each day. This allows users to choose between a steady data allotment or a per‑day allocation depending on their usage habits.
