im creating an ASP.NET page using C#
and want it to send messages to certain people.

i looked at some websites, like clickatell.com and intellisoftware.com
but they don't met the requirements.
clickatell block my country, and intellisoftware don't cover all the networks.
so is there some other web services that are good or some programs (or something of the sort) that allow me to send messages through a phone with a sim card in it, ofcourse using ASP.NET/C#
