Quick path for can't download apps on cellular on iphone 15: - Install the latest iOS update available, then retry. - Set Date & Time to Automatic, then retry if sign-in/downloads are failing. - Check Apple System Status; wait if the App Store has an incident. - Switch networks (Wi-Fi vs cellular) and retry download/update. - Sign out of Apple ID (Media & Purchases), restart, sign back in, then retry. - Disable VPN/Proxy and re-test downloads. - Check Screen Time restrictions that may block installs/purchases. - Restart iPhone and retry the exact failing action. - Force-close the affected app (if applicable), then reopen and retry. - Confirm iPhone has free storage space (a low-storage state breaks many flows).
