On the Phone
Make and receive phone calls, and set up appointments.
Phone Korean is harder than face-to-face Korean because you can't see facial expressions or gestures. This lesson covers the formulaic opening and closing phrases that every Korean phone call uses, plus how to make appointments and reservations.
Opening: 여보세요 (the universal phone greeting, used as 'hello?'). Asking for someone: [name] 씨 계세요? (is [name] there?). Identifying yourself: 저는 [name]인데요 (this is [name]). Booking an appointment: 예약하고 싶어요 (I'd like to make a reservation), [time]에 가능해요? (is [time] available?). Closing: 감사합니다. 안녕히 계세요. Mobile communication has shifted heavily to KakaoTalk messaging in Korea, but phone calls remain essential for restaurant reservations, customer service, and any urgent communication. Practice the formulaic openings until they come out automatically when you hear the line connect.
~(으)ㄹ까요? — Shall we? / Do you think?
Verb stem + (으)ㄹ까요? is used to suggest something together or ask someone's opinion. 가다 → 갈까요? (Shall we go?), 먹다 → 먹을까요? (Shall we eat?)
~(으)면 — If / When (condition)
Verb stem + (으)면 = if/when. Consonant stem → 으면, vowel stem → 면. 가다 → 가면 (if you go), 먹다 → 먹으면 (if you eat).
How It Works
-(으)ㄹ까요? asks for the listener's input, and the crucial feature is that the decision has not been made yet. 갈까요? genuinely opens the question of whether to go. This distinguishes it sharply from -(으)ㄹ게요, which announces a decision already taken.
The form works both as a suggestion including the listener ('shall we?') and as a request for opinion about yourself ('shall I?'). 몇 시에 만날까요? proposes; 제가 갈까요? offers. Context decides which reading applies, and Korean does not mark the difference.
-(으)면 builds conditionals and is mechanically simple: consonant stems take 으면, vowel and ㄹ stems take 면. 시간이 있으면, 모르면, 가면. It covers both 'if' and 'when' — Korean does not distinguish a hypothetical condition from a temporal one the way English does, so 비가 오면 can mean either 'if it rains' or 'when it rains' depending on context.
Phone conversations rely heavily on both. The conditional lets you set up contingencies and the -(으)ㄹ까요? form lets you propose times without committing, which is exactly what arranging a meeting requires.
Japanese speakers will find -(으)면 maps closely onto 〜たら/〜れば, and the same ambiguity between 'if' and 'when' exists in Japanese too.
Where You'll Hear It
여보세요 is used only on the phone. Saying it in person would be strange, and this narrow specialisation catches learners who treat it as a general greeting.
Arranging to meet is the classic use of -(으)ㄹ까요?. 몇 시에 만날까요? and 어디서 볼까요? are the two questions that structure almost every social arrangement, and they pair naturally with the day and time vocabulary from Level 3.
잠깐만요 ('just a moment') is essential on the phone, where you cannot use gestures to signal that you need time. It also works in person when you need someone to wait.
예약하다 comes up for restaurants, clinics and accommodation. 예약하고 싶어요 states the want; 예약했어요 confirms it is done. Korean restaurants often take reservations by phone rather than through apps, so this is a genuinely necessary skill rather than an optional one.
Phone numbers use Sino-Korean numbers read digit by digit, with 공 rather than 영 for zero in spoken sequences. The hyphen is read as 에, so a number is often given as a string interrupted by 에 — a pattern that sounds confusing until you know to expect it.
Cultural & Language Note
여보세요 is used only on the phone — never face to face. It descends from 여기 보세요 ('look here') and has narrowed to phone use exclusively, so hearing it in person would be jarring. Koreans also tend to identify themselves immediately after it rather than waiting to be asked, which differs from Japanese phone convention.
Common Mistakes to Avoid
을까요 asks for the listener's opinion or suggests together; 을게요 announces your own decision. Answering 갈까요? with 갈까요? loops the question back instead of deciding. The conditional 으면 attaches to the stem, so 가다 becomes 가면, not 가으면 — the 으 appears only after a consonant.
How to Practice This Lesson
Contrast -(으)ㄹ까요? and -(으)ㄹ게요 directly, since they look similar and mean opposite things. Write five pairs: 갈까요? / 갈게요, 먹을까요? / 먹을게요. Say each pair aloud and state which one asks and which one decides. This takes ten minutes and prevents months of confusion.
Phone practice is uncomfortable but disproportionately valuable, because you lose all visual cues. Rehearse a complete call: 여보세요 — 예약하고 싶은데요 — 몇 시에 가능해요? — 그럼 일곱 시로 할게요.
Drill your own phone number until you can say it without hesitation, using 공 for zero and 에 for the hyphens. You will be asked for it more often than you expect, and stumbling over your own number is a needlessly frustrating way to fail a conversation.
Japanese speakers should lean on the 〜たら intuition for -(으)면 and spend the time elsewhere.
