How to kill the voicemail facility on an iPhone XR?
Solution 1:
Step 1: Go to your home screen and tap on the keypad icon at the bottom.
Step 2: Once the keypad is launched, type ##002# and then click on the Call button. There is no cause for worry since the iPhone will not actually make the call, but will display the settings of your voicemail.
Step 3: You will be presented with three different messages
- Voice Call Forwarding
- Data Call Forwarding
- Fax Call forwarding.
Do not do anything, but simply tap on the “Dismiss” tab at the bottom of the screen. You will have successfully disabled your voicemail for all types of calls.
