You could do this:

    def device = MessagingDevice.findByPhoneNumber(params.phoneNumber)

    // invoke deleteFromDevice on domain object, which returns number of objects deleted
    def count = messageInstance.deleteFromDevice(device)
    if (count) {
        flash.message = message(code: 'default.deleted.message', args: [message(code: 'message.deleted.label', default: '{0} Messages deleted'), count])
        redirect(action: "phone", params:[phoneNumber:params.phoneNumber])
    }

and in your messages.properties

message.deleted.label={0} deleted
