nextSIM for South Korea FAQ

Does nextSIM offer unlimited data eSIM for South Korea?

No. nextSIM does not provide a true unlimited high‑speed data eSIM for South Korea. Plans that carry “Unlimited” in their names deliver fixed amounts of high‑speed data—typically 1 GB or 2 GB per day—and beyond that threshold the speed is reduced (e.g., to 512 kbps or 2000 kbps). For travelers who need higher data volumes, nextSIM offers large fixed‑data plans such as the eSIM Republic of Korea 100 GB 30 days Standard or the 50 GB 30 days Standard, which keep full speed for the entire validity period. These fixed plans can be more economical for heavy data usage, but none of them are unlimited.

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

nextSIM does not provide South Korea eSIMs that include a phone number or SMS capability. The plans it offers for South Korea are data‑only, so travelers will not receive a local South Korean number with voice or text services.

Customers who need phone or text functionality can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but this may depend on local restrictions. It is advisable to confirm that the specific apps you rely on are accessible in South Korea before purchasing an eSIM from nextSIM.

How many data plans does nextSIM offer for South Korea?

nextSIM provides 31 single‑country plans for South Korea and 75 multi‑country plans that include South Korea. The available plans vary widely. Prices across all offers range from approximately $3.84 to $1, 278.53, while data caps span from 1 GB up to 100 GB. Some plans are fixed‑data, giving a set amount of data for the validity period, whereas others use a daily data cap, limiting the data available each day. The validity length of these plans also ranges from one day to ninety days, allowing travellers to choose a duration that fits their trip.
