Teacher SIM Korea for EPIK Arrivals | eSIM + KT Transition
Teacher SIM Korea just got easier. With the Korvia Teacher Welcome Package from Kimchi Mobile × KT, new English teachers land in Korea already connected.
A New Era for Teachers Arriving in Korea
For newly arriving English teachers, securing reliable and affordable mobile service in Korea can be surprisingly stressful. Kimchi Mobile, in partnership with KT, is transforming that experience with the Korvia Teacher Welcome Package—a service designed specifically for Korvia teachers to enjoy the same benefits as locals, minus the usual hurdles. From smooth onboarding to real cost savings, this package is crafted to meet the actual needs of foreign teachers.
What Makes the Korvia Teacher Welcome Package Special?
From a Korvia teacher’s perspective, here’s what sets this package apart:
- Instant Mobile Access
Land in Korea and get connected right away. The prepaid eSIM includes 3GB of 4G/5G data, 200 minutes, and 200 SMS, valid for up to 60 days—all at an incredibly competitive rate. - Effortless Transition to Postpaid
Once you receive your Residence Card (formerly ARC), you can switch to a KT postpaid plan with 25GB or 110GB data options and up to 34% off standard pricing—unlocking exclusive discounts that go beyond what’s typically available even to Korean nationals. - English-language support is available; ARC verification and plan-specific documentation still apply
Skip the usual maze of translations, forms, and multi-step verifications. This is a plug-and-play experience built for ease. - Flexible Options
Choose from three tiers—Budget, Basic, and (coming soon) Premium. Budget and Basic are already live, delivering generous data and voice at exclusive teacher-only rates, while Premium will unlock even larger data buckets and added perks once it launches this summer. Whether you stick with prepaid or upgrade later, you stay connected from day one—no store visits, no paperwork delays, service continuity depends on activation timing. - Full-Service Teacher Support
Kimchi Mobile’s role ends after your phone is activated and your Residence Card upload is verified—but KT takes over with customer support channels are available:

Frequently asked questions for English teachers in Korea
The right plan depends on whether you have an Alien Registration Card (ARC). New arrivals usually start with a passport-based prepaid eSIM or SIM, then transition to a 12-month KT postpaid plan after the ARC is issued. Kimchi Mobile packages both paths in one workflow.
Yes. Passport-based prepaid SIMs and eSIMs are designed for the window between arrival and ARC issuance. They cover the orientation period, school onboarding, and KakaoTalk verification with co-teachers.
Most recent unlocked phones support eSIM and work on Korean networks. Apple lists iPhone XS, iPhone XS Max, iPhone XR, and later as eSIM-capable. For Android, check your device settings for eSIM or mobile network add options.
A Korean 010 number makes KakaoTalk verification, banking, and food delivery apps simpler. Kimchi Mobile plans that include voice and SMS provide a Korean 010 number for the duration of the plan.
Both packages include a 60-day prepaid data window that bridges the gap between arrival and ARC issuance, followed by a switch to a 12-month KT postpaid plan once the ARC is ready.
No. Kimchi Mobile serves a wider foreigner audience in Korea, including international students, ARC holders, exchange program participants, and short-term travelers. EPIK teachers are one of the long-supported groups.
