Only Samsung knows when it will be available for their devices. Their flagship devices, i.e., the S24 Ultra, Fold, and S23 Ultra, will be first. Then, the rest of the devices will follow. So have patience.
The official release date for Android 15 One UI 7.0 remains unannounced. Following the launch of the S25 series, flagship devices will receive the update initially, subsequently followed by the S24 series, and finally mid-range devices. Precise release dates for all models are currently unavailable. Some reports suggest a February or March rollout for the S24 series, with flagship devices prioritized before mid-range models. However, there is no official confirmation regarding its Pakistan release.
