Make it make sense
Useful pattern
The pattern [noun] + 필요해요 means 'I need [noun]'. Put the thing you need directly before 필요해요. For example, 데이터 필요해요 means 'I need data', and SIM 카드 필요해요 means 'I need a SIM card'. To be more specific, add a descriptive phrase before the noun: 데이터 되는 SIM 카드 필요해요 means 'I need a SIM card that has data'. The verb 되는 comes from 되다, meaning 'to work' or 'to function'. This lets you describe the SIM card you want without a long sentence.
When to use it
Use these phrases at a mobile carrier store, a convenience store that sells prepaid SIMs, or an airport counter. Start with 데이터 되는 SIM 카드 필요해요. If the staff asks what kind of plan you want, you can answer 선불 요금제로 주세요, meaning 'Please give me a prepaid plan'. If you want to confirm the price, ask 얼마예요? If you need to know how long it lasts, ask 며칠 동안 쓸 수 있어요? These are all polite and appropriate for a service counter.
Listen to each line, then take one part and reply out loud.
안녕하세요. 데이터 되는 SIM 카드 필요해요.
Hello. I need a SIM card with data.an-nyeong-ha-se-yo. de-i-teo doe-neun SIM ka-deu pi-ryo-hae-yo.네, 선불 요금제 있어요. 며칠 동안 쓰실 거예요?
Yes, we have prepaid plans. How many days will you use it?ne, seon-bul yo-geum-je i-sseo-yo. myeot-chil dong-an sseu-sil geo-ye-yo?일주일이요. 얼마예요?
One week. How much is it?il-ju-il-i-yo. eol-ma-ye-yo?이 요금제는 삼만 원이에요. 여권 주세요.
This plan is 30,000 won. Please give me your passport.i yo-geum-je-neun sam-man wo-ni-e-yo. yeo-gwon ju-se-yo.A little context goes a long way
In Korean phone stores, staff often use polite formal speech with customers, so -요 endings and a friendly 안녕하세요 are appropriate. Prices are usually quoted in won, and prepaid plans may require identification such as a passport. If you do not understand, you can say 다시 말씀해 주세요, meaning 'Please say that again'. It is normal to ask for clarification; staff are used to helping visitors.
One thing to watch for
Saying 데이터 SIM 카드 필요해요 and expecting it to mean 'I need a SIM card with data'.
Try this instead: This can sound like you need two separate things: data and a SIM card. To show the SIM card has data, use the descriptive form: 데이터 되는 SIM 카드 필요해요. The word 되는 links 데이터 to SIM 카드 and means 'that has data' or 'that works with data'.
Your turn
Try answering out loud before checking a possible answer.
1How do you say 'I need a SIM card with data' in Korean?
Show a sample answer
데이터 되는 SIM 카드 필요해요.
This uses 데이터 for data, 되는 to describe the SIM card, and 필요해요 for 'I need'. You could also say 데이터 있는 SIM 카드 필요해요; 있는 is another natural way to say 'that has'.
2You want to ask if a prepaid plan is available. What do you say?
Show a sample answer
선불 요금제 있어요?
선불 요금제 means prepaid plan, and 있어요? asks 'is there / do you have'. At a store, this is polite and clear. You could also add 혹시 at the start for a softer tone.
3Ask how much it costs and how many days you can use it.
Show a sample answer
얼마예요? 그리고 며칠 동안 쓸 수 있어요?
얼마예요? asks the price, and 며칠 동안 쓸 수 있어요? asks how many days you can use it. You can ask them separately or together. The verb 쓸 수 있어요 means 'can use'.
Remember the key sentence 데이터 되는 SIM 카드 필요해요, then ask 얼마예요? and 며칠 동안 쓸 수 있어요? to complete your SIM card purchase in Korean.
