No long-term contract is required. Service is available in periods of at least 30 days. Foreign customers can apply with a Residence Card or passport. If you do not top up for the next period, service is suspended and the number is later terminated under the carrier policy. Identity-verification availability can vary by registration details and the service used.

₩36,000 range｜Calls, texts and low-quality YouTube
Yes. After the first 300MB of high-speed data is used, the connection continues at up to 3Mbps, so YouTube can be watched at a reduced video quality. KakaoTalk, maps and web searches also remain usable. High-quality video and large downloads may be slow, and actual speed varies by location, time and network conditions.
- People who make and receive many calls
- People who mainly use Wi-Fi at home or work
- People who use KakaoTalk, web search and low-quality YouTube
The high-speed allowance is only 300MB, but data continues at up to 3Mbps afterward. The price is ₩36,000 or ₩36,300 depending on the network.
₩39,000｜15GB and up to 3Mbps
- People who use around 15GB per month
- People who use maps, social media, web browsing and video
- People seeking a balance between price and data
The plan includes 100 call minutes and 100 text messages. After 15GB is used, the speed is up to 3Mbps. If you make many calls, compare the ₩36,000-range plan as well.
₩66,000｜100GB and up to 5Mbps
- People who often use mobile data without Wi-Fi
- Heavy users of YouTube, video calls or tethering
- People who need up to 5Mbps after using 100GB
This plan suits heavy mobile-data users. Light users should check their actual usage first to avoid paying more than necessary.
