Why isn't the weather displayed on Apple's mobile phone?

The weather on Apple's mobile phone is not displayed, probably because there is no WIFI connection or the 4G network cannot be updated. Open Apple's mobile phone, enter the main interface, find the "Settings" icon, and click. After entering the setting interface, slide the screen up to find "Privacy" and click. After entering the privacy interface, click-Location Services. After entering the location service interface, slide the screen up to find "Weather" and click. Select Always, as shown in the figure, and the status will be considered as selected. Go back to the main interface of Apple's mobile phone, slide down from the top of the screen, then enter the drop-down notification bar and click-Edit. After entering the editing interface, slide the screen up, find "Weather" and click. After selecting the weather, click Finish.
