Classroom Korean and phone Korean are cousins, not twins.
On the phone you can’t rely on bows or facial expressions. In texts, people shorten everything and sprinkle endings that never appear in your first textbook chapter.
This beginner guide covers useful phone and text phrases without pretending you’ll sound like a teen on KakaoTalk overnight.
First: formal or casual?
Same rule as real life.
- Teachers, staff, new contacts, anyone older / higher status → polite
- Close friends who already use 반말 with you → casual
If you’re unsure, stay polite. You can always loosen later. Going casual too early is harder to undo.
Phone: answering and starting
Polite answer:
여보세요?
Hello? (phone)
Yes, it’s different from 안녕하세요. Phone culture has its own opener.
Polite self-intro on a call:
안녕하세요. 마이클인데요.
Hello, this is Michael.
(Replace with your name.)
If you dialed them:
안녕하세요. 저 마이클이에요.
Hi, this is Michael.
Phone: can’t hear / bad signal
These are gold:
잘 안 들려요.
I can’t hear well.
신호가 안 좋아요.
The signal’s bad. / Connection isn’t good.
다시 말해 주세요.
Please say that again.
잠시만요.
One moment.
Phone: ending the call
Polite:
끊을게요.
I’ll hang up. (common closing)
통화 고마워요. / 통화 감사합니다.
Thanks for the call. (choose politeness for the relationship)
수고하세요.
Used toward people still working / in certain service contexts — learn it, use carefully.
For more goodbye nuance, see the goodbye guide on Ready Korean. Phone closings and in-person closings overlap but aren’t identical.
Texting: the polite basics
Safe messages:
안녕하세요.
Hi (polite)
지금 괜찮으세요?
Is now okay? / Are you free now?
나중에 연락드릴게요.
I’ll contact you later. (polite)
확인했어요.
Got it / Confirmed.
알겠습니다.
Understood. (polite, workplace-friendly)
감사합니다!
Thank you!
Exclamation marks are common in friendly texts. One is enough; five looks like a sticker explosion.
Texting: casual (only if 반말 is established)
지금 괜찮아?
Free now?
나중에 연락할게.
I’ll message later.
ㅇㅋ / 응 / ㅋ
You’ll see these. Don’t lead with them toward your teacher.
ㅋ and ㅋㅋ are laughter particles in text. Useful to recognize. Easy to overuse.
Scheduling over text
Polite toolkit:
내일 가능하세요?
Are you free tomorrow?
몇 시에 만날까요?
What time should we meet?
조금 늦을 것 같아요.
I think I’ll be a bit late.
도착했어요.
I’m here / I’ve arrived.
These four handle a shocking percentage of real beginner logistics.
Voice notes vs typing
If spelling slows you down, send a short polite voice note:
안녕하세요, 저 마이클이에요. 내일 세 시에 괜찮으세요?
Speaking can be clearer than broken Hangul typed with the wrong autocomplete. Both skills matter — pick the one that keeps the conversation moving.
Etiquette quick hits
- Don’t call early morning or late night without a reason.
- For first contact with a business or tutor, text politely before calling if that’s the local norm for that relationship.
- In group chats, read before firing questions already answered.
- Emojis are fine; spammy sticker storms at a professor are not.
Practice drill (5 minutes)
Write three polite texts in Hangul (phone notes app):
- Greeting + your name
- “I’ll be a little late”
- “Thanks for the call / thanks!” after a study session
Then read them aloud as if you’d say them on the phone. Text and speech should feed each other.
Ready Korean
Use Lesson sentences for politeness patterns, and keep formal vs casual straight before you copy drama texting slang. Dramas are fun teachers — not always safe copy-paste for your boss.
Bottom line
Phone Korean starts with 여보세요, clear signal phrases, and clean endings.
Text Korean starts with polite defaults, scheduling lines, and the discipline to stay casual only when the relationship already is.
Master the boring basics. The slang will find you on Kakao whether you like it or not.
