Keep getting AT&T plan ready to be installed even though it is already installed. How to I get rid of this notification?

We want to help provide a solution to the notification you're receiving on your iPad, @Pbastedo. 

Here's how to access and edit notification settings on your iPad device:

• To access notifications settings, from the home screen select the  Settings app.
• Select Notifications, then adjust settings as desired.

If this doesn't help, we have a few recommendations we'd like you to try: 

• Restart your device. ~ This is a quick resolve to most errors you receive on your device.
• Toggle Airplane mode on and off. ~ This will help sync your device to nearby towers. 
• Reset your network settings. ~ This will help restore the default settings on the device. 

You can also sign in to our Device Support tool for step-by-step troubleshooting tutorials. 

Please keep our community updated on how this works for you.
