DLC is usually in 12 bit download code format, and there is an online store entrance in the host for code exchange. Similar operations can be carried out in online stores with computer web pages.

It should be noted that the version of DLC should correspond to the service you entered in order to be successfully redeemed. For example, the Hong Kong version of the alloy you bought, DLC is the Hong Kong version, which can only be exchanged when you enter Hong Kong, and the national service, Japanese service and American service are invalid.
