The other day I came across an sms gateway, since I was looking for some solution for our small retail company. The first one that seemed reliable was the ozeki ng sms gateway and to tell the truth I never heard about it, but its a good point that it was written in c# and our engineer is good at this programming language. Do you happen to know any other sms gateway that is similar to ozeki's solution? Or do you have any kind of experience with this one?
