I’m considering purchasing a larger quantity of this modem. I would like to get some feedback from other people that tried it. Has anyone has seen any major issues with it?
I did not use the breakout board. I used my target device with a Maxim RS232 chip to connect to the computer. You should be able to use the breakout board with an external power supply, but I have not tried it myself.
I’ve updated the firmware on several modems. The most important thing is that the power to the modem has to be OFF when you click the Download Now! button. Turn the power on a few seconds after clicking the button.
Try AT+AIPDCONT=“wap.cingular”, I’m not sure however if it will work or not.

Just in case anyone else needs it…
I got this sucker working. This is how you pull a web page:
OK ;test serial communications
+CPIN: READY ; make sure SIM card is ready
+ICCID: XXXXXXXXXXXXXXXXXXXX ; Read SIM card serial number if you need it
+CSQ: 16,99 ;Check Quality of service, first number must be > 0 but not 99
+AIPDCONT: "internet”,“”,“” ; set APN server, check with your SIM card provider
+AIPA: 1,10.110.234.135,0,0,0 ;Connect with APN server
+AIPO: 1,“10.110.234.135”,4770,“22.214.171.124”,80,0,30,1,0,64000,8,7300,5720,-500,0) ;Connect to web server
+AIPW: 1,0,7300,5720,18 ; Send "GET / HTTP/1.0\r\n\r\n” string to web server. It must be converted to ASCII HEX format
;You should get several lines of reply back from the server, also in ASCII HEX format
OK ; Disconnect from the server
No public wish lists :(
