Why do SMS web service prices vary so much? How does this service do a better job than Penny SMS who charge $0.01/message and provide return messages via email? https://www.pennysms.com/
SMS prices vary so much depending on the quality of service you want. At Poll Everywhere we pay a premium to SMS aggregators to have a short code (99503) and higher priority connections to cell networks. You could tap into the SMS network entirely via email, but the latency is too high for our needs.
The situation is awful, and paints a nasty picture of what the web would look like if it were not for net neutrality.
