Just put %hash inside bless {} directly ...

$self = bless {
  'intpref'    => $intpref,
  'prefix'     => $prefix,
  'telnum'     => $telnum,
  'smstext'    => $smstext,
  'cookie_jar' => "lwpcookies.txt",
  %hash,
}, $class;

... which has the added benefit of making defaults real easy, because the user can just insert a key/value pair for whatever they want to override (ie, 'cookie_jar' in the above: if it exists in %hash, the new value will replace the default), saving you of going through the motions of 'key' => exists $hash{'key'} ? delete $hash{'key'} : 'my default',.

And since you don't use %hash anywhere else, you could feasibly rid yourself of temporary assignments by reducing the above to...

sub new {
    my $class = shift;

    my $self  = bless {
      'intpref'    => shift,
      'prefix'     => shift,
      'telnum'     => shift,
      'smstext'    => shift,
      'cookie_jar' => "lwpcookies.txt",
      @_,
    }, $class;

    # ... other things with $self ...

    $self;
}
