# ofono (qmi) currently changes state to 'registered' jut after sending

# Which means we can reach lines below and send USSD code while still not being
# attached, which will then fail. See OsmoGsmTester #2239 for more detailed
# information.
# Until we find an ofono fix or a better way to workaround this, let's just
# sleep for a while in order to receive the 'Location Updating Accept' message
# before attemting to send the USSD.
