What kind of card should I use to travel to Korea?

The first is a mobile phone that supports 3G/4G.

Then you need a GSM and international roaming mobile phone card. If you don't mind the cost, I just want to say … well, let's be friends!

However, it is actually recommended to buy a Korean phone card in a food store run by people in China, Korea (just like the kind we sell on the street for tens of dollars, including X-minute calls and XM traffic). The general price is 65,438+00,000-30,000 won (65,438+00,000 won is generally less than 60 RMB), which can meet daily needs. It is very expensive to use GSM for international roaming.

In addition, because wifi is international, there are many free wifi signals in Korea. At this time, using QQ voice is completely free, and you can also video. The disadvantage is that it is not as convenient as using a mobile phone.
