Message Length Considerations:
- While the traditional SMS message length is 160 characters for GSM-7 encoding, it’s important to note that when using UCS-2 encoding (which supports a broader range of characters), the maximum length is 70 characters. If your message exceeds these limits, it will be segmented and sent as multiple messages, which may incur additional costs. Open Market
SMPP Parameters:
- Source Address (Sender ID): Ensure that the source phone number (Sender ID) complies with the regulations of the destination country. Some countries have specific requirements or restrictions regarding Sender IDs.
- Address Range: This parameter is optional and typically used to specify a range of addresses the ESME (External Short Message Entity) is authorized to bind to. If not required by your SMPP provider, it can be omitted.
- System ID and Password: These credentials are provided by your SMPP service provider and are essential for authenticating your connection to their server.
Security Considerations:
- When transmitting sensitive information, ensure that your SMPP connection is secure. Some providers support SMPP over TLS to encrypt the data in transit.
