I am going to travel abroad in a few days. Do I need to change my 4G phone when applying for international roaming?

In general, 4G can be used for international roaming. There is no need to change phones. For those that support WCDMA/GSM roaming, the WCDMA/GSM network is used. For those that do not support WCDMA roaming, the C network is used in Japan and South Korea. In other areas, the G network is used. All network selections can be made automatically by the terminal.
