OK

pu2. Isn't there no limit to tethering? I don't think there's a way for the carrier to know

OK

pu4. SKT has unlimited tethering, but KT heard there was a limit in the past, so it's using SKT

OK

pu5. I think there were no restrictions on some of the KT plans, and there were restrictions on others. I think it's better to find out which one is right?
