Can't Set APN (Access Point Names) Manually

Problem

When I try to access Access Point Names on my Android device, the menu option is grayed out and not accessible.

Cause

When the device is enrolled as Device Owner and you have installed an APN profile, the Access Point Names (in Settings→Connections → Mobile Networks) is locked by the system. The SIM card is linked to the APN profile and cannot be changed.

Solution

You need to remove the APN profile from the device. Before you do that, connect to Wifi or you may lose connection to your device!

Note

How to remove APN Profile

1. In CI Console, select Configuration Management and navigate to the device
2. Mark the APN profile, right-click and select Remove profile
3. Mark the device, right-click and select Get Inventory to contact the device
