If you would like to change your Trainer nickname, you can change it within the Settings menu. You can only change your nickname once, so choose wisely. Keep in mind that your nickname will be displayed to other Trainers.
To change your nickname:
- In Map View, touch the Main Menu
- At the top right, touch Settings
- Touch the Change Nickname menu option
Note: If you cannot see the Change Nickname menu option, you have already redeemed your one nickname change.
