Instead of providing a group wide setting, we are considering to provide the setting on the Device Management page. After selecting devices, you will pull down the Actions menu and select “Data Roaming…”. Then you select to enable or disable data roaming on their cellular WANs. After saved, IC2 will apply the option to the devices’ cellular WANs once.
For devices that you add to the group afterward, you will have to repeat the above steps once again. What do you think?
