Is there any plan that doesn't work with 3g or LTE data?

pu1. In that case, you just need to sign up for a phone, text plan

OK

pu2. If you sign up for a basic plan that usually costs about 12,000 won, you don't have any data at all, so you can apply for data blocking. If you don't apply for data blocking, you can't receive MMS (in other words, MMS consumes 3g and lte data, and if you apply for blocking, the data generated at this time becomes free). You must apply for a block. Then you can use the Wi-Fi freely

OK

pu5. If that's the case, I recommend a thrifty phone. If you don't have data, the fare is really cheap.
