As topic, the LINE app on my S3, is not working on mobile data. ONLY WORKS on WIFI.

everything works fine with WIFI, but when OFF wifi, and use on mobile data, I CANT receive msg, sent msg or do whatever with line. the msg always appear a RED exclamation and i keep resending but failed.

and if i connect with wifi again, those FAILED msg will send out SUCCESSFULLY.

anyone have any idea how to fix this?

I reinstall LINE many times already.
