Dear Bryce, you are doing a great job within the kingdom.

I am tacking a difficult question here, how can I send a WAP Push without store the message? I checked GSM 03.38 and 03.40 and read the UDH and DCS carefully, and tried to combined some bits to achieve it, but still failed. Here is my case:

UDH=0605040B8423F0; (06: length, 05: port map, 04: length, 0B84: port,23F0: port)
(A30601B0: WSP header)

I tried DCS from C8 to CF, and all failed. According to the standard, 1100 (C) can send the message without storing it. But obviously it does not work. Any clue for that? do we have to modify WSP header? Btw, I am using SE T618. Thanks a lot.

I don't think you're going to be able to achieve this.

Setting the DCS to indicate class 0 will work for a regular text message ... but when you direct a message to a particular application port, such as WAP Push, the DCS is not going to get carried through.

There is no attribute within WAP Push to indicate that a message should not be stored anywhere.

The best you might be able to do is to send another WAP push after the user connects to your URL link ... to delete the WAP push from the inbox.

But not all phones support this.

To delete a previously sent push, you send another push with a signal-action of delete against the same id. The NowSMS web interface has settings for doing this.
