Hi Junior2011, If your Samsung Galaxy S21 Ultra is stuck on the SIM test screen and can't complete the setup process, try the following solutions:

1. Restart your phone: Simple reboot might resolve the issue.
2. Remove and reinsert the SIM card: Ensure it's properly seated.
3. Check for software updates: Make sure your phone is running the latest software.
4. Reset network settings: Go to Settings > General Management > Reset > Reset network settings.
5. Perform a factory reset: Go to Settings > General Management > Reset > Factory data reset.
6. Check for SIM card issues: Try a different SIM card or contact your carrier.
7. Clear cache partition: Press and hold Volume down + Power button, then select "Wipe cache partition".
8. Contact Samsung support: If none of the above steps work, visit a Samsung service center or contact their support team.

Remember to back up your data before performing a factory reset. If you're still facing issues, it's possible that there's a hardware problem, and you should contact Samsung support for further assistance.
