Call waiting issue

[kmsgli]

Code:

to check:
as a user
$ sudo mmcli -m any --command="AT+CCWA=0,2"
as a root
# mmcli -m any --command="AT+CCWA=0,2"

to disable:
as a user
$ sudo mmcli -m any --command="AT+CCWA=0,0"
as a root
# mmcli -m any --command="AT+CCWA=0,0"

Code:

[manjaro@manjaro-arm ~]$ sudo mmcli -m any --command="AT+CCWA=0,2"
[sudo] password for manjaro:
response: '+CCWA: 1,1
+CCWA: 1,32'
[manjaro@manjaro-arm ~]$ sudo mmcli -m any --command="AT+CCWA=0,0"
error: command failed: 'GDBus.Error:org.freedesktop.ModemManager1.Error.MobileEquipment.Unknown: Unknown mobile equipment error: 258'
[manjaro@manjaro-arm ~]$

That is what i got from those commands.

first command seems to indicate that call waiting is on. call waiting is more less operator service.

my guess downgrade to lower networks has some issues, if using gui, disable and enable modem after selection of network technology. then try latter command again

Tried using the network options in the settings to downgrade to 2g network still with no luck. Peculiar no one else has reported this issue?
