@irvinewade I installed minicom on L5 and followed the above instructions with method B.
Here is what happens: I get into the modem ttyUSB1 and ATI returns the modem information.
I issue the two AT commands given It says OK. I disconnect from minicom (hang up) and turn off the modem as instructed. Then I flip the kill switch on and the modem reconnects with mobile telephony.
Again connect to it with minicom and isse
ATD6912345678
Nothing happens. It does not dial anything.
If I now issue
AT+BMRAT
it returns +BMRAT: FDD LTE
but there is no call going on as I said. If I go to the phone and now use calls to dialout it works (it does make the call) and on the minicom screen the AT+BMRAT now returns
+BMRAT: GPRS
So maybe I do something wrong? Could it be that gnome-calls is running and needs to stop somehow?
Moreover I noticed that if I change the NetworkMode to “3G 4G (preferred)” (as instructed by Azevedo) the phone can not make calls and can not receive calls. The only remedy is to return it to “2G 3G 4G (preferred)” and then it works again.
any help/ideas ?
