如何删除“插槽1：没有SIM卡”通知吗？ -- 4.4-kitkat 领域 和 notifications 领域 和 notification-bar 领域 android 相关 的问题

I'm using my phone as more of a tablet computer and less of a phone (I'm not using cellular radio, only wifi Internet), so I didn't put a SIM card in it.

The issue is - the notification that I don't have a SIM card in my phone always shows up in the notification bar:

I am already running the phone in airplane mode and then enabled wifi, but the issue persists. I also tried force stopping the 'Phone' app and it does remove the notifications, but it comes back after phone restart.

How do I disable or hide these notifications permanently?

The phone is a Lenovo A536. Android version is KitKat 4.4.2.

I've recently rooted my phone and installed NotifyClean (requires the Xposed Framework). I've set it to block the Mobile Data app's 'No SIM card detected' notification:

I've previously tried to fix this issue with Notifications Off but it stops working after a device restart.

The only way I can think of is to hide all of system UIs notifications. To do this, you need root access and an app called Notifcations Off. Once you've installed Notifcations Off, you can just turn off System UIs notifcations.

Option 1: You may try turning off "Show Notifications" check box by visiting Setting-> Apps -> All Apps.

From here, you can select the app sending this notification and un-check the "Show Notifications" check box.

In case if you are not sure which app sending these notifications, you can LONG PRESS the notification area itself, and system will show you "App Info" bubble. Click on it to navigate to Settings of that app.

Once you are in settings, you may turn off Notifications by un-checking the "Show Notifications" check box.

Below is the screenshot of another App to guide you to do this.

Option 2: In case if above steps don't solve the issue, you may need to use Xposed Framework You need to Root your phone for this to work.

Read about the Xposed Framework and how to install it from here. Verify if your handset is supported. You may want to look at : Status Bar Icon Hider
