# Contributed by Max Wölfing <ff0x@infr.cat>
# Version: 0.0.6
# KNOWN BUGS:
# - After suspend/hibernate the mobile broadband connection is not going to reconnect automatically (that's probably ok)
# and sometimes, the modem is PUK-locked afterwards. The netctl connection is still show as active.
# To fix this issue just run 'netctl restart <profile>'. This will also unlock the modem if required.
