If I run minicom or atcom I get no response from modem. This is a fresh OS install we had it working at one point but settings were not staying. Is there a way to hard reset the modem?
Please let me know what other information is needed. The SIM is good it works in another modem I have. I am working on a POC for using the raspberry PI and trying to find the easiest setup for modems.
mmcli -L
