Play Store Link: Hide Persistent Notifications ($2.49).Or you can head directly to the app's install page using the link below. To buy the Hide Persistent Notifications app, head to the Play Store and perform a search for the app like you normally would. Step 1: Install Hide Persistent Notifications
Don't Miss: Remove the 'Connected to VPN' Notification on Your Galaxy.
At $2.49, the app will let you hide any system notification, including others like the current VPN status and pending system updates. You'll need to install a third-party app to hide the alert for good - in this case, the aptly named Hide Persistent Notifications. Granted, you can snooze the 'No SIM Installed' alert by swiping sideways on the notification and hitting the bell button, but that's temporary. If you want to hide the pesky symbol and accompanying notification for good, there's a nifty app you need to check out right now. Your Galaxy's lock screen already lets you know there's no SIM card installed if it's missing on your device, so there's really no need to have a persistent icon for it on the status bar.
