I have already called my carrier provider but was informed that I have to check it with my phone provider. unfortunately, I have already tried manually turning off the call forwarding feature in my iPhone 6s thru settings>phone>call forwarding but it still automatically turns ON after some time.
iPhone 6s, iOS 14
Good afternoon Erikad29,
Welcome to the Apple Support Communities!
It sounds like you are trying to turn off call forwarding on your iPhone 6s, and we'd like to help.
The resource below will provide some guidance:
Set up call forwarding and call waiting on iPhone - iPhone User Guide
This feature is controlled by your carrier. But if you wish, you can tap
Settings > General > Reset > Reset Network Settings on your iPhone and restart the device to address the call forwarding setting.
Take care.
Is it possible to turn off automatic call forwarding
