SMS Help

I am .net developer looking to build a SMS engine that can send SMS;s
to multiple phone. Is there any API to that? I am interested to know if
there is any SMS protocol to send messages.

Please guide me towards avaliable documentation on how to build a SMS
engine.

Thanks,
Gopi

How are you intending to send these messages? Are you planning
to use a cellular device and lodge them over-the-air? Or do
you want to connect to an SMSC (message centre) via the
Internet, and lodge them that way?

The mechanisms are different.

You'll find a lot of information in GSM technical specification
03.40, with different aspects covered by GSM 03.38 and 07.05.
You can download these from www.etsi.org or www.3gpp.org

From a different perspective, www.winsms.com might be worth a
look as well.

John,

Thanks for the info.

I want to connect to an SMSC via internet.

Does the SMSC also support sending MMS messages?

I don't have any experience with direct SMS lodgement via the
Internet. It may be worth asking your carrier whether they
offer the service, or recommend anyone who does. Having found
a provider, hopefully they'll have good documentation.

If you don't have any luck, let us know and I'll have a look for
SMSC details on recent SMSs I've received with an alphanumeric
originator address (a sure sign of direct lodgement).

I'm not sure about MMS lodgement that way either.

Is there anywhere I can look up these acronyms?

SMSC? MMS?
