Ireland is an extremely complex SMS market and numerous filters are in place. A large amount of messages are being blocked and so Nexmo uses a direct connection to get around this heavy filtering and ensure messages are delivered.
This is a fully-featured route and handset delivery receipts are supported, as is delivery to ported numbers.
There are no known restrictions on Sender ID to Ireland.
There are no additional content restrictions beyond those in our Acceptable Use Policy
Other features/restrictions of note:
Handset delivery receipts are supported.
