It seems like you're having trouble finding the Supplementary Services settings on your Samsung S3 Ultra. According to the Samsung support page, the Supplementary Services settings should be accessible through the Phone app. Here are the steps to follow: Open the Phone app. Tap More options (three vertical dots). Go to Settings > Supplementary services. If you're still unable to find the Supplementary Services settings, it's possible that the option might be hidden or not available on your specific device or carrier. You can try contacting your carrier directly to see if they can assist you with enabling the feature. Additionally, you can also try checking if there are any software updates available for your device, as this might resolve the issue. If none of these steps work, please let me know, and I'll do my best to help you troubleshoot the issue further!
