What are SMPP Accounts?

If you send below 50,000 messages per day, our HTTP or HTTPS post API option is usually the most flexible and easily implemented gateway for bulk sms.

However, if you expect your traffic to be "peaky" - ie more than 10,000 per hour or more than 100,000 per day, we would recommend our SMPP interface.

SMPP is the industry standard interface for SMS text messaging. It's not entirely straightforward to set up, but once set up is fast and reliable.

SMPP accounts (sometimes called SMS API's) give more flexibility and functionality than our standard accounts. For the full specification please download our pdf whitepaper here

The document describes the connection procedure.

Note - although SMPP is a plain text protocol, it can be tunnelled over SSL in order to encrypt the authentication and data carried the protocol. We offer this option at no extra charge - please contact us for port assignments.

Our premium SMS SMPP interface differs slightly in specification - for the full specification please see our documentation
