I'm running into an issue when trying to obtain from the Pantech UML290 the current data usage on the Verizon network. According to Verizon, you can dial a special number "#DATA" and then they will send a SMS message to the Pantech UML290 with the current network usage. See these links for more details: http://support.verizonwireless.com/clc/features/calling_features/number_features.html http://news.verizonwireless.com/news/2011/07/pr2011-07-01d.html The issue I have is I cannot dial "#DATA" using standard AT commands. I can use the ATD#777 and ATD*99***1# to establish a 3G and 4G network connection, respectively; so I know that the UML290 responds to my AT commands correctly. However, when I try dialing "ATD#DATA", I immediately get an ERROR returned. I've also tried establishing a network connection using the QMI interface and then dialing #DATA, but I get the same error.Same here. ATD#DATA returns ERROR. I don't think the UML290 supports this feature via the AT port. VZAccess requests data usage via the WMC port using command 0x56, which I haven't gotten around to reverse engineering yet. In fact, VZAccess doesn't use the UML290's AT port at all, just QMI and WMC. So you're kinda out of luck here, at least controlling it with the AT port.To clarify, it appears that if you send an SMS to the number "900080004008" with the content "POUND_DATA", you'll get a reply back with your data usage. This is what VZAccess does using the WMC port and proprietary WMC commands. It works for SMS too though on /dev/ttyACM0. Where the following says <ctl+z>, you do really want to hold down the Ctrl key and hit the Z key; that's how AT+CMGS works in text mode. AT+CMGF=1 OK AT+CMGS="900080004008"POUND_DATA<ctl+z>+CMGS: 19809 OK <wait 5 seconds> AT+CMGL="ALL" +CMGL: 4,"REC UNREAD","xxxxxxxxxx","13/04/03,14:37:15+00" Est as of 04/03 2:49PM: Data Usage: 0.001GB. +CMGL: 2,"STO SENT","900080004008","13/04/03,19:37:13+00" POUND_DATA OK Dan Great find! I'll do a USB sniff on my UML290 to see if the VZAccess Manager sends the SMS to the same phone number. Nate
