Text message in laravel

I have this in my MailableRecover class

return $this->subject('Password Reset')
                ->view('mail.html.recover-password')
                ->text('mail.plain.recover-password');

How can I tell the code to use text version of email when sending text(sms) messages

Mail::to($user->mobile_number .''. $user->mobile_carrier, $user->first_name . ' ' . $user->last_name)
     ->queue(new MailableRecover($user));
