Which is more cost-effective than a local card to surf the Internet in Korea?

There are many ways to travel to South Korea to surf the Internet, but most of them are expensive and are not recommended. The best way is to rent a portable wifi, which is cheap, practical and has a strong signal. I have outlined the specific expenses, so you can compare and choose ~

1. Buy a 3G network card for 5G days, and one around 200 yuan. There are traffic restrictions, which are more expensive.

2. Open international roaming, so that mobile phones can be used as usual not only at home, but also abroad. However, the communication fee for international roaming is more expensive. Just like mobile, I consulted the deposit paid by 500 yuan at the passing counter before I could open the international roaming service. Internet fee 1 yuan per megabyte, with a daily limit of 50 megabytes. If you surf the Internet frequently, you may be disconnected every night.

3. rent a portable WiFi. For friends who travel with laptops, smart phones or iPad, renting a portable WiFi is the first choice. Here, I recommend that you rent a portable WiFi to roam the world. Their family has counters at many airports in China, which is very convenient to rent. You can also rent it in official website or Taobao, as long as you are in 20 yuan for one day, with unlimited traffic. The most important thing is to be able to use it with friends, and the network speed will not slow down.
