If I remember correct, you need be able to receive SMS for activating this service!

 

@OP: have you activated roaming on this SIM before you left Thailand? Without this it will not work outside. I am not sure about the Happy DTAC, but normally when roaming is activated you are able to receive SMS. One other question? Your mobile is able to work in the Japanese network?

No I have never tried to use it outside Japan, and it seems that I can't use the Japanese network, I have no signal at all. I'm wondering if I top up more the roaming will be available, but I don't want to waste money since I'm not sure if this will work.
PS: I have an android phone

 Hi, I bought this SIM card 2-3 months ago, and now I'm in Japan and I can't get signal/roaming to receive an SMS message with a verification code sent by the Line App, I just top-up 100 baht to see if I get some life signal but it doesn't work. Should I top up more? On DTAC website seems that they have a roaming package that cost 299THB/day (http://www.dtac.co.th/en/prepaid/services/roaming/package/unlimited.html) and need to be activated by calling this number *104*761*9#, but since I don't have signal I can't call it.
Did somebody face the same issue? Or have an idea how can I proceed to receive that SMS on my Thai number? Thanks
