How can I improve SMS transmission speed?

We take great care to ensure the system is as optimised as possible for your needs and provide an article on Reliability And Performance issues listing some of the steps which can improve efficiency when sending messages.

You may also wish to consider changing the SMS node that you connect to, or submit to multiple nodes at the same time. It is recommended that you submit to both sms1.cardboardfish.com and sms2.cardboardfish.com if a load balanced configuration is required. Submitting to more than one sms node at a time is usually unnecessary. Further information can be found here.

Note that if you are using the SSL encrypted port 9444, message throughput will be inherently slower due to cryptographic overhead.
