How can I force my network to carrier aggregation mode

I have em12g module. How can I activate the carrier activation mode. Can you list the various commands here. I actually want to force carrier aggregation for my network.

hi,Kizsmart_Ventures:
UE (or module) cannot force carrier aggregation. UE can only report to the network whether it has the capability of carrier aggregation according to the measurement report, and it is decided by the network side whether UE can achieve carrier aggregation under the current conditions.However, you can check whether the UE implements carrier aggregation through the command.

hi,Kizsmart_Ventures:
Have you not run AT Command over COM so far?
You just need to use a simple COM port debugging tool such as Comtone and execute the command"AT+QCAINFO".
