OK

pu2. I tried 2 types of LG and SK, but I couldn't use KT because it was expensive
Personally, I've used it several times, and I like LG better
More than anything else, I have a personal network work, but when I do this, SK forces me to hang up if there is no communication request to some extent
I inquired about SK, but they said they didn't know
I thought it was a problem with the program or setting, but when I changed it to LG, there was no problem at all
So the conclusion is that LG is good
