Can't read incoming SMS messages with AT+CMGL=ALL

I am using a PHP's Digital_IO to connect with a usb connected modem, I have been using a Digi Xbee LTE. I have it working great to send SMS messages, but can't find how to pull up the list of incoming messages.

This seems like a no-brainer, I have read a dozen tutorials like this one: http://www.developershome.com/sms/howToReceiveSMSUsingPC.asp#11.1 and they all point me back to AT+CMGL, which doesn't seem to be doing anything. Here is a console log. Near the end you can see a MSG (+CMT: "4805554667") I sent from my phone to the device show up unsolicited as it was received, but then it didn't seem to be stored anywhere.

The only thing I ever get back when I do the AT+CMGL is "OK". I tried pulling up individual ones using AT+CMGR=1-100 and got nothing back but "OK" I also tried changing where the "preferred storage" was using AT+CPMS, but couldn't make any headway.

So it turns out the Telit firmware version that is on the Digi Xbee LTE Cat1 doesn't support storing incoming messages. Here is the response I got from Digi.

The Telit LE866-SV1 modem running firmware version 23.00.002, does not support SMS Storage within the modem. This is a known limitation of that version of the Telit firmware which has been addressed in Telit firmware version 23.00.004 for which Digi has not implemented yet.
When using the current version of the XBee Code installed with bypass mode, you must configure the AT+CNMI to generate a +CMT notification and handle the incoming message immediately as they arrive.

So yes, with Telit firmware version 23.00.002, the AT+CMGL="ALL" will be empty. At lest until we release a new version that includes the updated Telit code.
