Rust SMPP Simulator

Testing SMPP integrations usually means borrowing a live carrier link or standing up a heavy vendor stack. This simulator removes that friction: point your application at it and drive realistic message flows from a browser.

Why a simulator

Carrier links are scarce, rate-limited, and unforgiving in test environments. A local simulator lets you reproduce edge cases - throttling, delivery receipts, malformed PDUs - deterministically and on demand.

A bind, in code

let mut conn = SmppConnection::bind(BindKind::Transceiver, &creds).await?;
conn.submit(SubmitSm::new(dest, message)).await?;
