DUXCELL and Telstra NextG

Apparently, many 3G modems are not set by default to access 950MHz channels.  After locating the following useful technical resource, Andrew has successfully enabled access to those frequencies:

First, Andrew was able to connect to the Sierra modem AT command interface:

Hope you find this useful, with Telstra Channels is set to 4 for data and info and whilst connection is live I can connect to Channel 3 to view config and run AT commands:

Here is my readout:

 

at!band=?

Index, Name

00, All bands

01, N/A (Defaults to ALL)

02, N/A (Defaults to ALL)

03, GSM 900/1800

04, N/A (Defaults to ALL)

05, GSM ALL

06, N/A (Defaults to ALL)

07, N/A (Defaults to ALL)

08, WCDMA ALL

09, N/A (Defaults to ALL)

0A, N/A (Defaults to ALL)

0B, N/A (Defaults to ALL)

0C, N/A (Defaults to ALL)

0D, N/A (Defaults to ALL)

0E, N/A (Defaults to ALL)

0F, N/A (Defaults to ALL)

10, WCDMA 900/2100

11, N/A (Defaults to ALL)

And success at enabling the NextG frequency band:

Looks like it came good after config mentioned before and a couple more power cycles:

 

OK

0B, N/A (Defaults to ALL)

0C, WCDMA 850 GSM 900/1800

0E, N/A (Defaults to ALL)

0F, N/A (Defaults to ALL)

10, N/A (Defaults to ALL)

11, N/A (Defaults to ALL)

 

Have now locked it in to WCDMA 850 and all is good!

Refer to the article link above for the full details.  That article is intended for a Cisco device with embedded Sierra WIC module, but the AT commands listed are the same.
