Open browser in your device and visit the website (http://bit.ly/3o0pIU6) you see at the top of this picture. Then scroll-down till you find an IMVU icon and click "Continue Reading" button to begin the process.
Right now you're on the IMVU mod page, please enter the details as it's displayed (use your own information) and choose the amount of Credits you would like to enjoy after the generation will be completed.
Please confirm that generation process has been completed and jump to another page which is mandatory to release your just generated IMVU credits to your game app.
Now you should see Security Activation page, click on "Activate" button and start the activation process which will take about 5-7 minutes.
Last step before enjoying your IMVU credits! Read the instructions at the top of the page and follow them. In my case I was needed to try few apps in order to activate security system which was a fun process for me.
After you complete your activation - Restart IMVU application and enjoy your credits!
