I ordered 3 1+1 product and this product as well. But only two came. The courier tracking number is the same, but there are only two. Judging from the size of the box you sent, they put it in a box that never fit three. I hope you check it out and send me another one or take some action. I absolutely love the product.

If you set the phone language to Chinese when connecting to the app, you can change it to Korean after registering.

I gave up on the call quality after looking at the reviews, and I am satisfied with the quality of the product.
