Which carrier has a good internet connection?

pu1. Google, FaceTock, Twitter, etc. have idc centers near Korea anyway, so the speed is good regardless of which one you use.
If you use a lot of websites with servers overseas, I recommend KT.

pu4. It used to be KT, but it's not like that anymore
KT is intentionally blocking bandwidth to avoid reducing usage fees for overseas networksIt's that
If you complain to the customer service center, only the site will be released
