At FreebieSMS we encourage developers to make use of our SMS gateway, via a rich
set of web services.
Our SMS services can be classified into "pay to use" or "reverse charged". Pay
as you use, is where the developer's company pays us 4p per text
sent, in advance. Reverse charged services is where the developer's
company pays nothing, but the reciever of the message will have the option to
pay to read it.
