Hi pmaa80,
I just wanted to add that there is an issue with the way AceManager presents the LTE CA status, and it’s very misleading. When it shows “Invalid” it doesn’t necessarily mean that CA is not enabled. Assuming that your band combination is part of the supported list (provided below), there is no reason for CA not to work. You can confirm that it’s working by going into Admin > Advanced > Radio Module Debug Information > Refresh. The output will show LTE CA STATE under AT!GSTATUS?. If the CA state is ACTIVE then you’re fine. I wouldn’t use the CA status in AceManager. We’re working on trying to get this fixed.
