Troubleshooting "User Busy" Message:
A. Try Updates:
Because you are using an iPhone, contact your Carrier, request carrier updates. Once they are installed, see if it then works. Go Here: Manually Update your Carrier Settings on your iPhone or iPad - Apple Support
Have a Computer Handy? If so, try using a computer to update. Go here: Update your iPhone Using a Computer - User Tip. If any updates are availabe, they will install, sure enough.
B. Restarting the iPhone:
If any changes were made (i.e. Installed Apps), then Settings (i.e Wf-Fi), may have become manipulated technically. So, try restarting the iPhone:
- Go To: Settings
- Tap: General
- Tap: Shut Down
- Slide: Your Finger to the Right
C, Reset All Network Settings to Default:
Example of items that will be reset: (Wi-Fi Passwords, VPN Connections, etc)
- Go To: Settings
- Tap: General
- Tap: Reset
- Tap: Reset Network Settings.
- Enter: [Your Passcode]
D. Try manually restarting your iPhone:
- Go To: Settings
- Select: General
- Scroll to: the Very Bottom
- Select: Shut Down
- Slide Finger: to the Right
- Wait: 30 Seconds
- Power One: the iPhone
- Try this Once More
As a least resort...
E. Restore to Factory Settings:
If you wanted to, you could restore your iPhone to factory settings, as if you were to sell it. All would be erased, the phone number would reside, and you'd log in anew to everything. Perform as instructed here, including iCloud log out and the backup creation: What to do Before you Sell, Give Away, or Trade in your iPhone, iPad, or iPod touch - Apple Support
