It is absolutely not true that MobiControl v13.x does not fully support 4G connections.  You might need to find out the real reason(s) why your devices cannot get connected to the MobiControl server via 4G connections.  It can be your device firmware, the telco operator switch/APN settings, erroreous set-up of data-plan or SIM card configurations, etc.

In the past, it was possible to force network mode of most Samsung devices to 3G/2G only with script command writesecuresetting augmented with relevant arguments involving "preferred_network_mode", numerical mode number, etc.    I did some tests on a few Samsung devices earlier today, and found that they no longer work.  Let's see if Soti support team can give us some updates on new script command or command syntax when they see this post.

Hi,

Which version of Android and MobiControl agent are these devices running?

Thanks

Hi,

The devices are running on Android 7 and the MC agent is version 13.3.2 Build 1106

Hi,

We also want to force all devices to run on 3G instead of 4G. Until now we didn't get it work and didn't find any solution for this. Did you manage to force them to run in 3G?

Are you aware we are in the middle of a worldwide shutdown of 3G as the preparation and shift to 5G is already underway? If you did end up forcing all of your devices to 3G with 4G disabled you could end up in a bad position later if 3G networks are shut down in your region.
