Selling your cellphones.How?

Hi, I'll be leaving Busan at the end of the month and I have two  cell phones that I want to sell but dont know how to go about it. The first one is a pay as you go phone that  my predecessor sold me the day I arrived. He just told me that to add credit to it I would have to use his name when going to the store. I did this for about a month which was fine but then one day the phone disconnected and when I rang customer service they said I needed to re-register with my alien card number. Not being the guy they thought I was I decided just to get a new phone. So, with this phone which I still have is it worth selling as I still have the recharger etc and I just use it as an alarm clock.

The second phone I bought was bought in an LG shop second hand for W90000. I will definetley sell but do I need to de-register with them (lg) and sell the phone on to someone or do I just sell the phone as it is and tell the buyer to assume my identity when putting on credit?

Any advice for boths phones would be great. Thanks.

You could try selling them on

You could try selling them on here. I don't know how you would transfer ownership on the pay as you go one. It seems you might need the permission of the previous owner by what you've said and that would require his alien card, which of course doesn't exist. And without an alien card you can't do jack in this country it seems!

The one under your name should be fairly simple. Take it to an LG shop (it's got to be an official shop) and they should be able to arrange transfer to someone else.

Failing that try one of the second hand phone stores down in the underground shopping malls in Seomyeon. They would probably take both off your hands, but probably not at a great price. But something is better than nothing.

Problem these days is a lot of shops offer pretty decent phones for free since they make the money on the contracts. So best scenario would be to sell to a newbie foreigner who doesn't know the system yet. Maybe not fair on the newbie, but Korea is a learning process and we've all been there!
