Hello Laurarhos,
Welcome to Apple Support Communities!
If we understand your post correctly, you want to know how to turn off Dial Assist. We're happy to help!
- Go to Settings > Phone.
- Do any of the following:
- Turn on Show My Caller ID: (GSM) Your phone number is shown in My Number. For FaceTime calls, your phone number is displayed even if caller ID is turned off.
- Turn on Dial Assist for international calls: (GSM) When Dial Assist is turned on, iPhone automatically adds the correct international or local prefix when you call your contacts and favorites.
- For information about making international calls (including rates and other charges that may apply), contact your carrier."
