Australia is an extremely complex SMS market and numerous filters are in place. SS7 networks are gradually all being shut down and a stable, direct connection is essential to ensure SMS delivery.
We are using fully featured connections therefore dynamic Sender ID, concatenated SMS and delivery to ported numbers are supported.
There are no additional Sender ID restrictions beyond those in our Acceptable Use Policy
There are no additional content restrictions beyond those in our Acceptable Use Policy
Other features/restrictions of note:
Telstra Australia (50501): delivery receipts are network-only receipts.
For all other networks, standard handset delivery receipts are to be expected.
