Messages on Samsung phones can be transmitted through either the network carrier or the non-archived Samsung service (which is transmitted over wireless data).
If you intend to use the Network Archiver or the Android Archiver, you’ll be required to disable the Samsung Enhanced Messaging service (so that all messages will be routed over the network carrier).
To disable Samsung Enhanced Messaging, the enterprise administrator should block messages for employees using an MDM/EMM tool or by using the Enterprise Samsung KNOX tools.
