6.4 Changing APN via the DM system
Since changing APN is a potentially hazardous operation that may render the device disconnected from
the mobile network, there is a rollback functionality in place when changing the APN.
To change APN, write the APN to the resource /10/1/1 and set APN mode to manual in /10/1/2. Once
done, stage the changes by executing /33906/0/15. When executed, the device will reset and try to use
the new APN. If the device manages a successful bootstrapping, the new APN will be saved as the
default. If a successful bootstrapping has not happened for some time, the device will roll back to the old
APN and reset again.
