I'm going to visit South Korea for 6 weeks, can I apply for $10 travel pass just for 1 or 2 days, and Pay as You Go for rest? (I already have a South Korean phone, so I'll use it that one.)
If I can, how can I do it? just make a travel plan with a travel planner site? or is there have any other steps?
And, if I use pay as you go, is there have any charges for just receiving service? (no data, message, and call. just for receiving service)
