Help with 4G card - can't get any modem to show up

uConsole
1

I have no modems, i don’t know why

alex@uConsole:~ $ mmcli -L
No modems were found

I am using 9001

I have enabled network manager (which seems to be a pre-requsite)
I have run the enable command.

alex@uConsole:~ $ uconsole-4g-cm4 enable 
Power on 4G module on uConsole cm4
waiting...
done
use mmcli -L to see 4G modem or not

I see the following in dmesg

[  334.938587] usb 1-1.3: new high-speed USB device number 5 using dwc2

I issue

echo -en "AT+CPIN?\r\n" | sudo socat - /dev/ttyUSB2,crnl

and i get the expected response (note it has to be on USB2 - USB3 didn’t work.

AT+CPIN?
+CPIN: READY

OK

however the ISP check returns the wrong response

echo -en "AT+COPS?\r\n" | sudo socat - /dev/ttyUSB3,crnl

gives

AT+COPS?
+COPS: 0

OK

my sim card is a boost mobile card, boost says it doesn’t need activating as it already is…

I am stumped at this point (this is my first time with linux and a cellular modem).

Help?

of course no sooner than i post this i try the following and it somehow worked (maybe it just took a while for the SIM to regsiter with the network?)

sudo systemctl stop ModemManager
sudo systemctl disable ModemManager
sudo ModemManger --debug

I saw at this point the logs registered the sim and mode, check with mmcli -L and this time it was there - so i quit the debug version, re-enabled the service and now all seems good… weird… i had been tryin this for an hour before i did the service bounce (i had tried reboots) and re-enable

oh it seems I have to 100% run sudo systemctl restart ModemManager after issuing uconsole-4g-cm4 enable - oh joy.

Still can’t get modem to register with network.

4

does this mean i have a signal issue or a basic sim / device activation issue (aka my apn settings might not be right?) there is nothing in journalctl -u ModemManager that is helping…

i am going to try a SIM from a different virtual mobile operator (MINT)

did Mint work for you?
