You can use the following variables: %{registered}, %{attachement}

=item B<--warning-technology>

Set warning threshold for technology.
Use special variables %{technology}.

Set critical threshold for technology (default: '%{technology} !~ /2G|3G|4G/'
Use special variables %{technology}.

=item B<--warning-signal>

Warning threshold for signal strength.

=item B<--critical-signal>
