Hello, can this mobile phone vivov3maxa be used in Korea? I'm going to start international roaming. Is it okay?

Vivo V3Max A theoretically supports the local 2G/3G/4G network of SK Telecom (LG U+) operators. Because the variables of foreign operators are large, what we find here is only the parameters on the network, so it is suggested that the actual situation should be based on the local usage.
