TL;DR
Several Samsung users have reported issues with mobile data, Wi-Fi, and SIM detection after updating to One UI 9.

A permanent fix hasn’t been discovered for any of the connectivity problems.
Samsung has been rolling out the stable One UI 9 update to Galaxy phones over the last few months. Although it introduces several new features and brings some Galaxy AI features to older Samsung flagships, the update process doesn’t seem to be going smoothly for everyone.
