I suspect that the call to json_load "$(cat /etc/gcom/ncm.json)" in ncm.sh causes the interface information to get lost, so that subsequent json_* calls no longer work correctly. We should somehow "unload" ncm.json after the necessary AT-commands are read, and then restore normal interface information. Or can we read ncm.json into a separate namespace or something? Maybe Felix or Steven could give some advice?
