SOLUTION: Apple iPhone XS Max - Some Call Services Can Now be Found in Settings

Symptoms

Some call services that were previously only available via * codes are now available via Settings > Phone.

These services include:

• Call Forwarding
• Call Waiting
• Show My Caller ID

 

Solution

Customers may experience the following when making changes to these services:

• If there is no cellular coverage, these cannot be configured. No impact if device is connected to Wi-Fi within cellular coverage, but if a user is in Airplane Mode (no cellular), connected to Wi-Fi, these services will remain unconfigurable.
• There can be a slight delay (5 seconds) when making changes (enabling/disabling) to these settings as the phone communicates back with Sprint services.
