I am sorry if I've missed this information anywhere... I am trying your service for a project in which I need to provide a two way SMS: user sends a message to your system, message is forwarded via HTTP, .NET API used to reply...

Is there any information in the received SMS that could be used to detect whether the original sender has MMS enabled, in order to reply with MMS instead? Or even better, is the MMS message .NET object able to act as multipart (i.e. with MMS disabled, the recipient will still get the text part)?

I need a reliable way to satisfy this business requirement; if your system does not provide these capabilities, are you aware of any company that will?

Many thanks

There is no way to determine MMS support in the way you described.

If you send an MMS message to a phone which does not support MMS then the user will receive an SMS message prompting them to go to a website to retrieve the message.

Thanks for the prompt reply...
Are you aware of other services offering this capability?

Regards

Sorry, I am not

Last question:

If you send an MMS message to a phone which does not support MMS then the user will receive an SMS message prompting them to go to a website to retrieve the message.

Can this be tailored / forwarded to our website?

Thank you

The hamdling of this is done by the destination network. There is no way to override this.
