I don't have one anymore. My phone doesn't recieve SMS calls for some reason (you need to get a number to register an account with KakaoTalk), so I had to use a temporary phone number to recieve one.

Apparently you need to actually have a permament phone number to keep your account, because when the temporary one expired, my account was essentially "dead". I couldn't change my phone number because of constant errors that lasted for days.

It's no big deal, really. I wasn't going to use it as a replacement for LINE Cookie Run anyway. I've invested way too much time and money on that. :P
