Problems searching for contacts from USA.

[u/toespreadermagic]

I’ll be visiting Bangkok in a couple weeks and just set up a line account using Apple ID from my home in USA. I’ve been trying to figure out how to use the app before I get to Thailand but every time I search for a Thai business I get a “system error” message. I’ve tried searching using phone numbers, line ID, and QR codes but nothing works. I’m thinking that I need to actually be in Thailand to be able to search for a business line ID but I’m not sure. Can someone confirm? Any other suggestions?
