Hi, I wanted to ask. I'm going with my family to Seoul, Busan and Jeju Island. The duration of our stay is 11 days. If I was to buy one of these sims, can I use it to tether for the other devices or will we all have to get a sim? Will it work in Jeju Island? Which one would be the best option? All our devices are unlocked so we don't have a problem in that way. Thanks for any help anyone can provide.
