I tried gammu :
sudo gammu getussd *123#
Error opening device, it doesn't exist.
my gammurc
device = /dev/ttyUSB0
connection = mbus
replaced ttyUSB0 with ttyUSB1 and tty USB2 but same result
i tried gsm-ussd
sudo gsm-ussd -m /dev/ttyUSB0
Can't get lockfile /var/lock/LCK..ttyUSB0 - probably already in use!
Same results with other two USB1 and USB2
i tried prepaid-manager-applet with setup of vendors and country.
We can't find the information on how to query the account balance from your provider 'Airtel' in our database.
