I purchased a Novatel Wireless
XU870. I pulled the SIM out of the iphone and plugged the SIM into the
XU870. I then plugged the
XU870 into my computer. I used the following dialup settings:
APN: wap.cingular
Username:
WAP@CINGULARGPRS.COM
Password: CINGULAR1
web proxy - wireless.cingular.com:80
I am able to connect to the Internet and surf. According to the LED on the
XU870, I am running on EDGE. The HSDPA / UMTS in my area is very spotty so most of the time, the
XU870 LED is violet colored, indicating EDGE. The speed I get is definitely EDGE speed. When I move to a balcony or window, I get the blue and green LED colors, which indicate UMTS / HSDPA. If I run a SpeakEasy speedtest when I have the UMTS / HSDPA connection, I get 429 kbps down and 233 kbps up. Clearly this is better than typical EDGE speeds.
Based on my tests, I believe that the iPhone SIM with a Novatel
XU870 and the settings above will allow you to connect to the high speed 3g UMTS / HSDPA data network that is run by AT&T / Cingular. However, when you do this, you will obviously not be able to use your phone. I cannot find any software that allows the SIM to be used to receive text / SMS while being used for data service. Verizon has software that does this for their aircards and it is quite handy, but I cannot seem to figure out if it supported or possible with the AT&T / Cingular / iPhone /
XU870 combination.
I will try to find an are that has good UMTS / HSPDA coverage and re run my tests to see how much faster I can go. Obviously one should not be using this except for the occasional jaunt.
