The Sierra Wireless 7700 is frequency locked to AT&T. I just found this the hard way! I had always been told that the GOBI were unlocked, maybe CARRIER wise they are, but GSM Band wise that seems untrue. They may be usable on other carriers by just changing the MEP code. If you would like to use your AirCard with a different service provider, you must obtain the AirCard modem’s MEP code from the service provider. Let me know how that goes....

MC7700 uses 700(B17)/1700/2100(B4) MHz GSM band - AT&T
MC7710 uses 900(B8)/1800(B3)/2100 (B1)/2600(B7)/DD800(B20) GSM MHz band - T-Mobile
MC7750 uses 777–787 MHz (B13) LTE, 746 - 756 MHz, (B13 LTE),1850–1910 MHz., 1930–1990 MHz PCS Verizon

Plus to use it with Linux, it must be a DIP unit, not a QMI unit.

The card operates either in QMI or DIP (Direct IP) mode - To identify what mode your card is in check the ProductID. Mine is a QMI, of course, as I would also like to use it with Linux. Though QMI is said to be much faster, it is limited to Windows.

0x68A2 = QMI (Windows 7 -10) as far as I know...
0x68a3 = DIP (Linux and Windows 7 - 10) as far as I know...

While I have read that there is a utility to switch the card from QMI to DIP, it is written for the Netgear 320U USB Device, which used the same chipset, hidden somewhere at:
http://www.netgear.com/search-netgear.aspx?q=aircard Use the search term" aircard 320u linux software" to find the software under your OS/Carrier to make this hack work. For more generic software like drivers and/or watcher you might just try "Aircard 320U."

I find it hard to believe that M300 programming board and two PC to perform this alchemy. Look here:

http://www.szelins.com/download/usermanual/H685_MC7710_from_DIP_to_QMI.pdf

There maybe hardware differences that separate the 7700 vs 7710, so my T-Mobile Data plan, so far, is useless. I am in a Hospital bed right now running a fever, trying to make this work! So it all may be taken with a H U G E grain of salt. If EVERYBODY already knows all of this, I missed that meeting. LoL!

OK, I just read a page in Japan that claimed that they ha never seen a locked MC7700 AirCard, so I am going to call the nurse to see if she has a Jeweller’s Screwdriver and verify it is truly locked to AT&T... Stand by!

Interesting. I'm about to get a MC7700 to play with. However I just noticed that Sierra QMI libraries are on the Debian non-free repos, but the unofficial Sierra Linux drivers are DIP.

The one I bought is unlocked. It should support B1, B4 and B17 LTE and 800, 850, 1900 and 2100Mhz UMTS. That should cover everything I need up here. Technically the MC7700 is AT&T "Certified" but not necessarily locked. Some of those bands can be used with other carriers.

Good to Know, I am at a point new where I am deciding to whether to install MC7710, or MV770 drivers.

I found this info on changing QMI to DIP for Linux.

Please..

I am not a Verizon fan. Nor a member of the Verizon club. I am not a member of the hair club for men either. :swords:
I do not even have a cell phone plan. I am pay as I go and use wifi only for data.
I just share information. It may not always be correct information either.

:D

:lauging: Sorry Shawn, Verizon must be "frighting words" up there where you come from! I just made my data more complete and wanted to call attention to it.

It's just taking bloody forever to get here. I have to wait for the guy to swim to Vancouver from Hong Kong, then rickshaw the rest of the way to Montreal to deliver it to me.

'the hell is a M300 debug board anyway?
