As title says, they are cut roughly at the 4th page. Is this a common issue or it's somehow my fault?

Android may not support texts longer than 4 pages. I will need to investigate.

I've already sent longer sms successfully, so I guess it's possible! It's not a big issue though, thanks for your work.
PS i'm using GoSms, don't know if it can be related somehow.

Sorry for pressing the wrong button ;)

I've sent longer messages than 4 pages both with my Nexus S and through competing sms-to-pc service BrowserTexting. I prefer this app's layout and more reliable sending of messages, but the 4 page limit is really a clincher for me as the whole reason I use this app is to send long text messages from the comfort of my computer. If this issue was resolved I would definitely purchase this otherwise excellent program!

I'll be investigating this problem this week.

What's the forecast?

This is still affecting me: incoming messages show full-length within the stock Android messaging app, but are truncated after four-SMS' worth in the DeskSMS webapp. Can't confirm whether this affects the IM and email flavours of DeskSMS as I don't use them, but the webapp is definitely affected

This has been affecting me for a few months as well. Messages sent from the webapp are cut off after 4 pages, and incoming messages cut off after 4 pages. Any updates on this issue?

This has been an issue for more than 1.5 years now.
Sent a E-mail about this: 25/11 - 2011

4 pages != 4 actual pages, it's 526 characters which is about 3 pages + 10 characters.
"4 pages" == "4" multi-part text messages (not MMS or traditional SMS)

The problem is that mostly European network providers have a different understanding ov concatenated SMS, which in short is multi-part messages (SMS) sent in the same SMS.

To overcome this limitation Android converts any messages longer then 526 characters into a MMS.
This is something DeskSMS doesn't support, it simply tries to send the message as a TEXT message (SMS) and there for android will crop it down to whatever is supported.

Depending on how "low-level" DeskSMS is it could theoretically send UDH directly via the phone and thus being able to send ~255 "pages" long SMS via proper multi-part sms, or it could simply tell Android to send a MMS if the text-length goes above 526 characters.

Also, receiving MMS will be coped at 526 characters for some reason, most likely this is because DeskSMS tries to retrieve the message as a TEXT message rather then multi-part data or MMS?

DeskSMS shows pictures when I receive an MMS with an image attached. If so, it wouldn't be too much of a stretch to send messages over 4 pages as an MMS from DeskSMS, correct?
