The SMPP certification checklist — how buyers validate throughput and failover before committing
Before high-volume SMS moves to an SMPP bind, buyers run a certification battery: baseline throughput against the negotiated window, throttling response under saturating TPS, hard failover with sequence-safe resubmission, and encoding plus UDH mapping on the languages they actually send. This checklist gives buyers the four test classes, a sandbox-first order of operations, and a BYO-SMPP plan where the tenant owns every control.
