I used line with my cell phone in Taiwan. After moving to the US, I got a new cell phone and a different phone number. When I tried to download the app to my new cell phone, it wont let me log in. The app sends a verification code to my old cell phone number in Taiwan. There is no way to log in without the verification code. USELESS! I didnt like LINE when I was in Taiwan. Now, its at the top of the list for all apps that I hate! With FREE SMS and iMessage, is LINE even relevant anymore?
