Cannot Verify Phone Number on iPhone 11 Pro

Hi there

Please try this

• Check Date and Time: Go to Settings > General > Date & Time, turn off "Set Automatically," and manually select your correct time zone and location. 
• Disable VPN: If you are using a VPN or proxy service, turn it off under Settings > General > VPN & Device Management, as Apple often blocks verification requests from virtual networks. 
• Use a Phone Call Instead of SMS: On the verification screen, tap "Didn’t Get a Code?" or "Can't get to your devices?" and choose to receive an automated phone call instead of a text message. 
• Verify Phone Number Rules: Ensure the phone number is not already tied to another primary Apple ID (Apple restricts each phone number to a single main account) and avoid using VoIP or virtual numbers like Google Voice. 
• Manage Account via Web: Log into your Apple Account via Apple ID Management on a computer or mobile browser, and update or re-verify your trusted phone number under the account security settings before signing in on the iPhone 11 Pro.
