You either need to use some sort of gateway sofwtare from
your cell provider, or just use SMTP to send an email to
the sender's phone. The target phone's provider will turn
that SMTP message into an SMS and send to the phone.
This is not a limitation of .NET, since to do this
directly you would need (or at least have access to) an
SMS\WAP gateway directly.
