SMPP
On this page
Connect over SMPP 3.4 on port 2775 (TCP) or 2776 (TLS) for high-volume SMS, using the SMPP credentials from the Customer Portal.
SMPP
We also provide an SMPP interface for high-volume users. SMPP is available on the canonical port 2775. An encrypted, secure connection is also provided over TLS (1.1 or 1.2) on port 2776.
We highly recommend you connect via TLS in order to securely transport your messages to us. The normal, non-TLS connection is provided mainly for legacy backwards compatibility reasons.
Authentication
Authentication is done by SMPP credentials you received from TSG team or can be found in the customer portal.
