Ask HN: What services are available for sending/receiving SMS/MMS messages?
Looking for a reliable low-cost service.
This is the service we decided on at my old job. Our only difficulties were that we're based in Australia. The messages were sometimes slightly delayed (not by more than 30 seconds or so though)
I believe they are free and make their money for advertising. They share the short code though, so you signup for a specific keyword at first.
