Hi

My wife is in my country and wanted to fix something that requires opt code from Thailand, but thing is she doesn't receive it on her Thai number. But when I send her message on her Thai number she gets it.

What I found out either enable roaming but can she do that outside Thailand? Or do we need to vpn to Thailand? Or do we have to send an family member to dtac shop?

Many thanks in advance 🙏

Everything else question, I'm about to visit in two weeks for two weeks. Phone service plans, what do you do, what do you recommend?
