How to Add T-money to an iPhone in 2026 — Charging with Foreign Cards for Tourists, Apple Pay Transit Card Requirements, and Android Samsung Wallet

Can You Use T-money on an iPhone Without a Korean Card?

Yes. But you have to choose the right entrance.

Apple has pinned down the route of creating T-money directly in Apple Wallet: 「a credit card or check card issued in Korea is required」. Without a Korean card, this route is blocked.

Instead, if you create the card through the Mobile T-money (모바일티머니) app, you can charge it with a foreign-issued card. The supported brands T-money lists in its app introduction are Mastercard, American Express, and UnionPay, and its update notes also mention JCB. Apple Pay charges it directly inside the app. Visa is not on this list — if you only have Visa, go to the "When You Only Have a Visa Card" section below.

On Android, the Samsung Wallet transit card charges onto the phone's USIM, and the Mobile T-money app is also available on Android.

1) iPhone — Create It with the Mobile T-money App and Charge with a Foreign Card

This is the route for travelers without a Korean card. T-money states that when the card is issued through the app, both issuance and charging work without a Hyundai Card.

Registration steps — Install the Mobile T-money app and issue a card within the app. The T-money card then appears in Apple Wallet.

Charging — In the app you can charge from a bank account, KakaoPay, Naver Pay, or mileage, and foreign-issued cards (Mastercard, American Express, UnionPay, JCB) are charged directly in the app via Apple Pay.

Express Transit Card — Go to Settings → Wallet & Apple Pay → Express Transit Card and select T-money. With this turned on, you only need to hold the phone to the fare gate.

2) iPhone — Create It Directly in Apple Wallet (When You Have a Korean Card)

This is the route for people with a credit or check card issued in Korea. You buy it with a Hyundai Card registered to Apple Pay.

Registration steps — Open the Wallet app, tap the add button → Transit Card → select T-money from the list → Continue → choose the amount to load and tap Add. You charge it in the Wallet app with the same card.

T-money in Apple Wallet is prepaid only. There is no postpaid version, and convenience store payments and online payments do not work — treat it as transit-only.

3) Android — Samsung Wallet Transit Card and the Mobile T-money App

The Samsung Wallet transit card works by charging T-money or Cashbee onto the phone's SIM card, prepaid or postpaid, and using it over NFC. It works in both card mode and basic mode. Samsung's guidance only goes as far as 「the phone's USIM」 — there is no guidance on SIMs bought abroad or travel eSIMs.

The Mobile T-money app is also on Android. T-money states in its Android guidance that you can charge from a bank account, check/credit cards, or phone billing.

4) Top-up Methods Compared

The same T-money card takes different money depending on which entrance you used. Here it is in a table.

5) When the Phone Dies, and What Doesn't Work

Even when the battery runs out and the phone turns off, T-money keeps working for up to 5 hours in power reserve mode. Even if the battery dies in the evening, you still get through the fare gate.

Some things do not work. T-money in Apple Wallet does not support convenience store payments or online payments, and only the prepaid version is supported.

6) Buying T-money at Incheon International Airport and Gimpo Airport

Incheon International Airport — Incheon International Airport is on T-money's official list of sales and recharge locations. The same list includes convenience stores (GS25, CU, 7-Eleven, MINISTOP, Story Way, Emart24, 365PLUS), subway station recharge machines and customer service centers, and the T-money Town at Seoul Station Exit 10. A physical card works right away with no ID, no sign-up, and no app. Charging is in 1,000 won units from 1,000 won up to 90000 won, with a maximum of 500000 won per card.

Gimpo Airport — The airport has Gimpo Airport Station, served by Line 5, Line 9, and the Airport Railroad. The recharge machines and customer service centers at the subway station are T-money sales and recharge points, so once you arrive at Gimpo, buy and charge the card at the station.

When leaving — Hand the card to a sales or recharge location and say how much you want back, and they refund the balance. A 500 won fee is deducted, but if you have spent 80% or more of the charged amount and then suspend the physical card in the Mobile T-money app, there is no fee. If Korean is a barrier, press 9 at the Seoul Metropolitan Government's Dasan Call Center at 120 for foreign-language support.

7) When You Only Have a Visa Card

Visa is not on the app's foreign card charging list. Even so, there are 2 routes.

One is the 440 new transit card ticket machines at 273 stations on Seoul Lines 1–8. From 2026-03-17 they accept credit and check cards issued abroad, and the example the Seoul Metropolitan Government gave was 「Visa, Mastercard, and others」. Here you can buy Climate Card (기후동행카드) short-term passes (1-, 2-, 3-, 5-, and 7-day passes) and single-ride tickets, and an average service fee of 3.7% applies.

The other is to charge a physical T-money card with cash at a sales or recharge location. The card itself needs no app and no sign-up, so this is the most reliable option.
