Frequently asked questions

Which SMPP version do you support?

We support SMPP 3.4 with transmitter, receiver, and transceiver bind modes.

How do I get SMPP credentials?

Contact our team to provision an SMPP account. We provide the host, port, system ID, and password, and whitelist your source IP for a secure bind.

How many binds can I open?

You can open multiple concurrent binds per account. Window size, throughput, and bind limits are set to match your plan and expected volume.

Do you send delivery receipts over SMPP?

Yes. Delivery receipts (DLRs) are returned on your receiver or transceiver session so you can track final message status in real time.

Do you support Unicode and long messages?

Yes. We support GSM 7-bit and Unicode (UCS-2), with automatic segmentation and concatenation of long messages.

Can I use SMPP and the HTTP API together?

Yes. SMPP and our REST (JSON) and XML APIs share the same account and reporting, so you can combine them or use SMPP as a failover path.
