How to forward calls on iPhone? Based on the current models and iOS versions. Please note that the steps may vary slightly depending on the iOS version you're using, so it's always a good idea to check for any specific changes in your iPhone's settings.

To forward calls on an iPhone, follow these steps:

Open the Settings app on your iPhone's home screen.
Scroll down and tap on "Phone" or "Phone Settings," depending on your iOS version.
In the Phone settings menu, look for "Call Forwarding" and tap on it.
If call forwarding is disabled, tap the toggle switch to enable it.
Enter the phone number to which you want to forward your calls. Make sure to include the country code, area code, and the full phone number.
Once you've entered the number, tap "Back" or "Done" to save the settings.
Now, whenever someone calls your iPhone, the calls will be automatically forwarded to the designated number you entered. Make sure you have a strong cellular or Wi-Fi connection for call forwarding to work properly.

Please keep in mind that call forwarding may incur additional charges from your service provider, so it's advisable to check with them beforehand to understand any potential costs or limitations associated with call forwarding on your specific plan.
