What works in Korea without a Korean phone number, and what doesn't

Can I travel around Korea without a Korean phone number?
Yes, for getting around, buying a transit card and booking restaurants. Where you get stuck is Korea's mobile identity verification. Every Kedanto Korea eSIM is data-only, so there's no Korean 010 number and no SMS. Calls and texts to your usual number still reach the SIM you already have. LG U+ says the same about its own data-only traveler SIM: "SMS verification is not available." Each verdict below comes from official guidance we checked on 11 September 2026.
| Service | Verdict | Notes / alternative |
|---|---|---|
| Taxi hailed on the street | No number needed | Cash, card or Tmoney |
| Tmoney transit card | No number needed | 3,000–5,000 won |
| KakaoMap | No login needed | Search and directions |
| CatchTable Global | No Korean number needed | Email, Google or Apple sign-up |
| Uber | Works with your home account | No country change needed |
| TADA | Home number works | Foreign card |
| KakaoTalk | Home number works | No virtual numbers |
| Coupang, Coupang Eats | Phone verification required | FAQ covers residents only |
| Bank and government identity checks | Korean identity verification | Even a traveler voice SIM fails |
| Kakao T, k.ride | Not confirmed | TADA, Uber |
| Baemin, Tabling | Not confirmed | Shuttle Delivery, CatchTable Global |
| KTX online booking | Not confirmed | Station ticket office |
If most of what you need sits in the top seven rows, finish every sign-up with your home number before you fly. Once you land, the data comes from a Kedanto Korea eSIM.
What can I do in Korea without a Korean number?
Can a foreigner take a taxi in Korea without a Korean number?
In Seoul, hail a taxi on the street or queue at a taxi rank, and you need neither a number nor an app. The Seoul Tourism Organization (서울관광재단) transport guide says taxis are easy to flag down, ranks are common, and most cars take cash, credit cards and Tmoney. Sign-up only comes into it when you want to book a car in an app. That's covered in the Uber and Kakao T question below.
Do I have to register to buy a Tmoney card?
No. You buy a Tmoney card (티머니) over the counter and load money onto it. The Korea Tourism Organization (한국관광공사, VisitKorea) says the cards are sold at convenience stores such as GS25, CU and 7-Eleven, and at the information centers of Seoul subway lines 1 to 8. They cost 3,000 to 5,000 won. The only registration it mentions is for under-18s who want the youth discount. At a convenience store, you hand over the card and say how much to add. Tmoney's official blog warns that some station top-up machines take cash only.
Do Korean map apps work without signing in?
KakaoMap (카카오맵) lets you search and get directions without logging in. Kakao's help center says basic map use, including search and directions, works without an account. Favorites, saved home and work places, reviews and syncing across devices need a Kakao account. Kakao's service page lists routes by public transit, car, walking and bike, but it doesn't say whether the app comes in English. Naver Map (네이버 지도) does. Naver said in December 2024 that the app runs in Korean, English, Chinese and Japanese and shows real-time transit arrivals. That announcement doesn't cover signing up. For Google Maps, a review council of the Ministry of Land, Infrastructure and Transport (국토교통부) conditionally approved exporting Google's 1:5,000 map data on 27 February 2026. The announcement gives no date for when that will change directions in Google Maps.
Can I book a restaurant or join a waitlist without a Korean number?
Yes, at restaurants listed on CatchTable Global (캐치테이블 글로벌). Its App Store listing says "No Korean phone number required." You can book more than 8,000 restaurants with your email and a credit card, and search in 20 languages. Confirmations arrive by email and in-app notification. You can also join a restaurant's waitlist remotely before you walk over. VisitKorea's guide, published in September 2024, adds three points:
- You can sign up with a Google or Apple account.
- You can pay with a card issued outside Korea.
- Only restaurants that take reservations charge a deposit. Remote and on-site waitlists don't.
What works with my home phone number?
Can I use Uber or Kakao T in Korea with my home number?
Uber works with the account you already use at home. For Kakao T, we couldn't confirm it. Uber's help center says the service "is available in any area, regardless of the country automatically set up when you sign up for your profile." That means you can use it abroad without changing the country setting. In Korea, the Uber app calls licensed taxis in Seoul, Busan, Daegu, Daejeon, Incheon, Ulsan, Gwangju, Gyeongju, Bundang/Seongnam and Jeju. Uber's Seoul page says you can choose "in-person payment" and pay the driver in cash or by card at the end of the ride. You can also add a credit card to your Uber account instead.
Kakao T (카카오 T) is less clear. VisitKorea's ride-hailing guide (last updated October 2025) says you first need a Kakao account made through KakaoTalk, and that "You can use your local mobile number to sign up." It doesn't say whether a KakaoTalk account made with a foreign number gets you into Kakao T.
Kakao Mobility built a separate app for visitors, k.ride. You don't need a Kakao account. You enter a phone number and then verify with Google, Apple or email. The app takes cards issued abroad, as well as Alipay+, WeChat Pay and GrabPay. Its screens are in English, Japanese and Chinese. In Korea it calls Kakao T Blue, Venti, Black and deluxe (모범) taxis. None of Kakao Mobility's pages say which country codes the phone field accepts, so we've listed k.ride as not confirmed.
The ride-hailing app that VisitKorea explicitly says "accepts international mobile number for app sign up and credit card for payment" is TADA (타다).
Can I sign up for KakaoTalk with a foreign number?
Yes. KakaoTalk (카카오톡) works with 230 country codes, and the verification text goes to your home number. Kakao's help center tells you to pick your country code, enter your number without it and complete SMS verification. To prevent spam, it doesn't accept "virtual numbers, internet phone numbers, etc." Sign up while you're still at home. If the verification text fails to send, Kakao says to ask your carrier whether your line can send messages, including overseas. Kakao also warns that repeated sign-up or verification attempts can get your use restricted.
What should I do with my home SIM when I add a Korea eSIM?
Keep your home SIM on and switch only cellular data to the Korea eSIM.
- iPhone: Apple's Dual SIM guide has you choose the data line under Settings › Cellular › Cellular Data. Both numbers can still send and receive texts.
- Pixel: Google says you can choose which SIM handles data, calls and texts.
If you turn your home line off, a re-verification text has nowhere to reach you in Korea. Before you fly, ask your home carrier what it charges to receive texts abroad and whether it can block data roaming. Apple's own travel guide warns: "You might still incur roaming fees from your home eSIM." To check whether your phone takes an eSIM at all, see our device check page. For carrier locks, see what to check on your phone before you buy.
Can I make or receive calls on a data-only eSIM in Korea?
Not on the Korea eSIM. Your calls go through your home number. Any call to or from your phone in Korea is an international roaming call on your home line and may cost extra. That includes calling a restaurant and a taxi driver calling you. When a form asks for a contact number, give your home number with its country code. For calls that don't use a phone number at all, Kedanto's FAQ suggests data calling apps like WhatsApp or KakaoTalk.
Where does Korean identity verification stop me?
Bank and government identity checks stay closed to travelers, even with a Korean number. Korea's mobile identity verification (휴대폰 본인확인) works by sending a code to a phone line registered in your own name with a Korean carrier, according to KISA's identity verification portal. LG U+ says its traveler SIM with a 010 number, calls and SMS passes the text check in restaurant and taxi booking apps. But it also says: "Identity Verification for banking or government services is not supported." We couldn't confirm how the SKT and KT traveler SIMs handle this. For an example of this blocking a public booking, see our Seokjojeon reservation post.
Can I use Coupang or Coupang Eats without a Korean number?
Coupang's own FAQ requires phone verification even for foreigners who live in Korea. The FAQ (July 2026) says foreign residents can join Coupang (쿠팡). It also says phone verification is needed so the company can send order notices, and that service is restricted without it. Other points from the same FAQ:
- Prepaid phones can't pass the real-name check.
- Coupay (쿠페이) requires a phone line registered in your own name with a Korean carrier.
The FAQ is written for residents and doesn't mention visitors. Coupang Eats (쿠팡이츠) bases its perks on Coupang's WOW membership.
What couldn't we confirm from official guidance?
Can I order from Baemin without a Korean number?
The only delivery app that official guidance says works without a Korean number is Shuttle Delivery (셔틀딜리버리). VisitKorea says you can "Sign up without a Korean phone number" and pay with a foreign credit card or PayPal. The app is in English, Japanese and Chinese, but menus are only in Korean and English. That guide lists these service areas:
- Seoul: Yongsan, Gangnam, Mapo, Seodaemun, Jung, Jongno and Gwangjin
- Pyeongtaek
- Busan: Haeundae, Gwangalli and Seomyeon
- Daegu: Nam-gu
The list dates from May 2025, and we couldn't confirm today's coverage.
Baemin (배달의민족) says on the App Store that it "is now available in English, Chinese, and Japanese." The app uses your phone's language setting. Its engineering blog (February 2024) describes sign-up as "Continue with phone number" (휴대폰번호로 계속하기). That flow uses Korean carrier identity verification with your name, date of birth and phone number, and the post says nothing about foreign numbers. We found no official statement that visitors can sign up without a Korean number.
Can I join a Tabling waitlist with a foreign number?
Tabling (테이블링) collects your mobile number and a CI (연계정보) when you join. A CI is the identity code that Korean identity verification issues. The privacy policy (effective 18 November 2025) includes a "foreigner or not" field, but it doesn't say what number a foreigner signs up with. Tabling sends its notices through KakaoTalk AlimTalk (알림톡). Its terms also say a booking may be refused or cancelled automatically if the number you book with doesn't match the one you signed up with. The App Store lists the app in Korean only. We also couldn't find out whether the waitlist tablets at restaurant doors accept a foreign number. For queuing, restaurants on CatchTable Global are the safer option.
Can I book the KTX without a Korean number?
Since 1 September 2026, high-speed trains to and from Suseo (수서) are also booked as KTX. You book them in the Korail+ (코레일+) app, on the Korail website or at station ticket offices. SR said its SRT app and website would run only until 31 August, so you don't need a separate SRT booking.
According to SR's Q&A on the merger, a non-member ticket in Korail+ arrives by KakaoTalk AlimTalk at the phone number you enter. The Q&A doesn't say whether a foreign number is accepted. Korail's English booking site is at korail.com/global/eng/main. VisitKorea lists an English-only Korail customer center at +82-1599-7777, open 08:00–20:00. Korail's official guidance doesn't confirm whether a visitor can finish an online booking without a Korean number. If you can't, buy your ticket at the station ticket office.
What should I do when an app asks for a 010 number?
If the number field has a country-code list in front of it, pick your country and get the text on your home number. If the field only takes 010, switch to an app that does the same job:
- Taxis: TADA or Uber
- Restaurant queues: CatchTable Global
- Food delivery: Shuttle Delivery
For bank and public bookings that open an identity check, go back to a counter or turn up in person. The time a Korean data line matters most is when you're on the street, downloading a new app and getting through its sign-up.
Sort your data out before you fly
You keep your SIM and add one data line. Your home number stays on your usual SIM; whether its calls and texts reach you abroad depends on your home carrier's roaming.
