Regularly play Ultimate Team on your console or PC and engage in various modes and objectives. Additionally, make sure to log into the Web App every day. These activities help EA recognize you as an active player. Most active users gain access to the Transfer Market in the Web App within a few days to a week.
*An active day involves playing 3 full matches in Ultimate Team and logging into the Web App within a single calendar day (UTC time). Remember that playing more than 3 matches per day won't speed up the unlocking process.
