APN Stops Working After Changing the SIM Card

Problem

The SIM card was changed in an Android device enrolled as Device Owner. The mobile network doesn’t work, even though an APN profile is installed.

Cause

An APN profile is linked and locked to the SIM card. Changing the SIM card or setting the profile to waiting doesn’t help, because the APN profile is still locked to the old SIM card.

Solution

Remove the APN profile from the device before you insert the new SIM card, and then apply the APN profile again.

Before you start

• The device must have CapaInstaller Android Agent 2.2.15 or later.
• Connect the device to Wi-Fi before you remove the profile or the SIM card. Otherwise, the device can lose its connection to CapaInstaller.

Follow these steps in this order:

1. In the CapaInstaller Console, go to Configuration Management and find the device. Right-click the APN profile and select Remove Profile/Application. Wait until the profile is removed from the device.
2. Remove the old SIM card.
3. Insert the new SIM card.
4. Apply the APN profile to the device again in the console, and wait until it’s installed.

The mobile network works with the new SIM card.

Important

APN profiles are supported on devices enrolled as Device Owner on Android 9 and later, and on Samsung devices with a KNOX license.
