What Kimchi Mobile B2B covers

Pre-arrival eSIM distribution: activate the group plan before arrival in Korea so the team lands with data ready.
Korean 010 numbers: for groups that need voice and SMS verification with KakaoTalk, banking, and Korean services.
ARC transition path: for long-stay foreign staff or students, prepaid plans on arrival and a switch to postpaid after the Alien Registration Card is issued.
Single point of contact: one account manager handles the team setup, billing, and renewal cycle.
English-speaking support: support for HR, international office, and international patient service staff, in English.

How the B2B workflow runs

Share your group size, arrival timeline, and use case in the contact form below.
Kimchi Mobile responds with a plan structure and quote tailored to the group.
Once confirmed, the team receives pre-arrival eSIM QR codes (or physical SIM cards if needed) and onboarding instructions.
On arrival, the team activates the line and the data starts counting from that point.
For long-stay teams, we coordinate the ARC pathway and postpaid transition.

Why Korea-native B2B matters

Korea has three nationwide mobile network operators (KT, SK Telecom, LG U+) and a long list of MVNOs. Most B2B mobile is sold as direct carrier contracts or through Korean-language resellers, which is a hard fit for international staff and program coordinators who need English support, foreigner ARC understanding, and visibility into the prepaid-to-postpaid transition.

Kimchi Mobile has supported foreigner customers in Korea since 2010 and operates the group workflow in English. For background on the Korean mobile landscape from a foreigner viewpoint, read Korea MVNO for foreigners.

Frequently asked questions

What is the minimum group size for a B2B plan?

Kimchi Mobile B2B is designed for groups of foreign staff or students who arrive together or share a single point of contact. For small groups, individual product pages may also be a fit. The contact form lets you describe the group, and we recommend the right structure.

Can you ship eSIM QR codes before arrival?

Yes. eSIM QR codes can be emailed to the team or HR contact before arrival. The eSIM profile installs on each member’s phone in advance and stays dormant until activated after landing in Korea.

Does Kimchi Mobile support physical SIM cards for groups?

Yes. For groups whose members have non-eSIM phones, physical SIM cards can be coordinated. Mixed eSIM and physical SIM groups are common for cohorts with different device generations.

How is the B2B group billed?

Billing structure is set during the quote process. Common options include a single invoice to the school or company, individual billing to each member, or a hybrid where the program covers the initial period and members handle later renewals.

Does Kimchi Mobile cover voice and SMS for groups?

Yes. Data-only plans are available for short-term cohorts, and plans with Korean 010 numbers, voice, and SMS are available for groups that need them. For long-term residents, the path includes a postpaid plan after ARC.

What if a member leaves the program mid-plan?

Plan transfer, cancellation, and refund options vary by plan type. The account manager can adjust the group during the term as members join or leave, within the limits of the carrier and plan agreement.
