If you wish to send once-off, high volume message batches (especially from legacy systems) than FTP is best suited to your needs. With FTP you can send concatenated messages, use ringtone and logo converters, and set up sender ID, delivery acknowledgement, batch sending and two-way messaging. You will also have access to gateway escalation and queuing, which lets you specify up to 3 prioritised queues according to which your messages will be sent out.
