Portuguese operators are shutting down more and more cheap SS7 routes and a stable, direct route is now necessary to ensure sms deliverability. Nexmo is offering a local direct route into all networks in Portugal!
This direct connection to Portugal is fully featured including handset delivery receipts, dynamic Sender ID and delivery to ported numbers.
Portuguese Carriers do not allow Shortcode Senders. We strongly recommend the use of Numeric Senders in International format or Alphanumeric Senders for all traffic to Portugal to bypass this blocking.
Please note that operators are now filtering on Russian numeric senders throughout Portugal. We therefore strongly advise against using any Russian senders into Portugal as messages are extremely likely to be filtered.
Update February 27th 2014:
Please be advised that Sender ID's listed below have been blocked locally, therefore any messages sent using these Sender ID's will likely be blocked.
If you have a valid contract to use any of the Sender ID's listed below, please contact our help desk and we will work with our suppliers to assist.
