Hi All,
I am a new mobile application developer.
I have managed to send text SMS to a midlet with Now SMS gateway by supply the UDH with port number, eg: udh=06050420082008 for port no. 8200.

This is working:
http://10.10.10.53:8800/?PhoneNumber=91370775&udh=06050420082008&Text=Hello+how+ r+u%3F

However, when the message is exceeding 152 characters(8 bytes used for UDH), the midlet listening to port 8200 is able to receive but cannot correctly decode the message. Following will display garbage in the midlet:
http://10.10.10.53:8800/?PhoneNumber=91370775&udh=06050420082008&Text=kdfiojfslf oufosuogudoguifduiogosjgljgosufgiodosgljdgjoiuodflgjldfgdlfiiiiiiiiiikkkiiiiiiii iiiiiklfjhgsljgdlfgiiiiiiijjjjjjkfffffdgjdjdjdjdjdjdjdjdjkgllllllllllll

But if I removed the UDH option above, it will go the phone's normal SMS box with correct content. I guess maybe there is uncompatible encoding scheme between Now SMS Gateway and Java WMA regarding of long message segmentation and reassembly.
Or did I miss some options? I tried to set the DCS=F5 and DCS=04, but these will result in receiving binary message in the midlet, that is not what I want. I want text message larger than 152 characters, anyone can help me?


I check the SMS out log:

The later two SMS is without specify UDH and correctly deliver to SMS box.

I think it is the port number specified in UDH affects the decoding, because it works exact the same way like sending long message from midlet to Now SMS Gateway.
In the midlet, when I use
MessageConnection con = (MessageConnection) Connector.open("sms://:8200");
to send message longer than 152 letters, it will be a decode error. However, when use

MessageConnection con = (MessageConnection) Connector.open("sms://phoneNumber");
everything works fine. Strange, is it?

Hi,

I can confirm that there is an encoding problem when submitting a long text message that includes UDH in this manner.

I have escalated this issue with our product development engineers. Unfortunately, I do not have any suggestions for a work-around at this time.

We are currently working on an update to address some issues with Windows Vista, and hope to include a fix for this issue in the patch. We are targeting this to be in the next 2 weeks.

Good news!

There is a "preliminary" fix available that addresses this problem.

It is included with an update release that addresses some Windows Vista compatibility issues, so the download is somewhat large. The download link is http://www.nowsms.com/download/nowsmsvista.zip

(The download is not specific to Windows Vista, it continues to support XP/2003/2000.)
