# What are the binding options for SMPP connectivity?

SMPP offers three bind types: Transmitter (send only), Receiver (receive only), and Transceiver (send and receive). At SMSGatewayCenter, bind as Transceiver for two-way SMS or Receiver for delivery reports—Transmitter alone won’t get DLRs. Use your system ID and password from your account. Check our [SMPP connectivity guide](https://www.smsgatewaycenter.com/smppConnectivity/) to configure this with our **SMS gateway**—up to 5 sessions allowed by default.
