Simsima for South Korea FAQ
Does Simsima offer unlimited data eSIM for South Korea?
Simsima does not provide a truly unlimited high‑speed eSIM for South Korea. The plans that carry the name “Unlimited” give 3GB of data each day; once that amount is used the speed is throttled to 1000 kbps, so the data is not unlimited.
If you need a large, flat amount of data instead, Simsima offers fixed‑data plans such as 100GB for 180 days at $84.00 USD, 50GB for 30 days at $34.86 USD, and 20GB for 30 days at $14.41 USD, all of which provide 5G coverage in South Korea.
Does Simsima offer South Korea eSIM with phone number and SMS?
Simsima does not offer South Korea eSIMs that include a local phone number or SMS capability. Travelers can purchase only data‑only plans from Simsima for use in South Korea. Voice and text can still be carried out over the data connection via VoIP applications such as WhatsApp, Telegram, and iMessage. Since some destinations may block or limit specific VoIP services, travelers should verify that the apps they intend to use are accessible in South Korea before making a purchase.
