Can cdma2000 be used for traveling in Korea?

CDMA2000, also known as CDMA multicarrier, was proposed by Qualcomm North America Company of the United States, and Motorola, Lucent and Samsung of South Korea all participated. At present, South Korea is the leader of this standard.

Pay attention to this sentence: South Korea has now become the leader of this standard. I believe that Korea supports CDMA2000 without explanation.

At present, CDMA2000 mainly covers seven countries (regions) in Japan, South Korea and North America: Canada, the United States, Mexico, Greenland (Denmark), Guatemala, Bermuda (Britain), Saint Pierre Island and Miquelon Island (France).

As can be seen from the above, CDMA2000 can be used in Korea, but it is not this frequency band that can be used to receive and make calls in Korea. At the same time, there must be a mobile phone card and services that support international roaming. In addition, the consideration cost is also high. In today's technological progress, it is actually recommended to surf the Internet through wifi (this is universal), and QQ voice, video, YY and the like can all achieve the purpose of calling. Of course, it is more troublesome than calling directly; If you talk a lot, you can also buy a Korean phone card, which generally ranges from 1 0,000 to 30,000 won (don't be afraid, 1 0,000 won is roughly equivalent to 55 yuan RMB). You can make a fixed-minute international call. If you have more phones, you can consider it. If you have fewer phones, you don't have to.
