When traveling to Korea, I recommend using the wowpass card. It has two modes of use: as a debit card and as a Tmoney public transportation card. These modes don't overlap. You can't transfer money from one virtual wallet to the other. This is the only inconvenience. Otherwise, the card makes traveling around Seoul and South Korea much easier.

I've been using Trip Esim in my almost all travels abroad. And this one was the cheapest among everyone. It never fails to have a good data connection. You can even renew the plan. But I opt to buy another esim since phones nowadays can install more than 1 esim. It is hasse free compared to physical sims that needed to remove your phone case to place the simcard.

Perfect for people coming to China. Easy to use, convenient, connects to the internet and works fine, not too slow.

I used this for four days during my trip to Korea.
I usually use WiFi, but this time I tried this service. It was easy to set up and I just had to switch it on when I arrived, so it was very convenient. I was able to use it on the subway and everywhere else without any problems, so I'd definitely use it again when I travel!
