      That is my issue.  No windows 7.  I will. Hold out a system with windows 7.

        I would try first with Ubuntu and make sure it connects. Like I say the IMEI numbers can get blacklisted. You seem to have an OEM variant looking at the picture(SKU=110-1882). That is why it uses a different IEMI prefix(3594). Plus you can tell by the 2012 firmware date it is an early model. Plus it is marked A0 module. I think 1882 SKU is Panasonic OEM number.

        I can tell you the earlier modules sometimes need to be brought up to date in stages. See if you can find something from 2013 for firmware then do the newest..

        Have you tried flashing with the newest QMI firmware from Windows. I think it may be in QMI mode as per your pfSense output.
        Then you could flash with DIP firmware. You probably also need the Windows QMI drivers to load the card. Also the Sierra watcher is only DIP for QMI it uses a different app called Skylight watcher.

          I say its in QMI mode because my dmesg looks like this;

          
root@E6420:~ # dmesg |grep u3g0
u3g0: <sierra 0="" 3="" wireless,="" incorporated="" mc7700,="" class="" 0,="" rev="" 2.00="" 0.06,="" addr="">on usbus1
u3g0: Found 6 ports.</sierra>

            Also the modules PID changes for QMI mode. So if you can pull up a terminal you can switch it to DIP. Then install DIP drivers in Windows and flash it with DIP firmware.

              Finally got it to work.  I guess not giving up eventually pays off!

              Found a post regarding a tool to switch from QMI to DIP

              Post:

              https://forums.lenovo.com/t5/ThinkPad-T400-T500-and-newer-T/T430i-and-MC7700-in-DIP-mode-will-not-boot-System-is-Halted-Was/td-p/3367435

              Tool:

              http://hptouchpad4g.com/Support/sierra/windows/ModeSwitch/BZ31018_DIP_QMI_ModeSwitch.zip

              I probably read over 80 forum postings before I could find this!

              After running tool PC required reboot and now device is DIP mode

              Output from my Putty attached.

              Ok so now the next step.  How to get this working with Carrier T-Mobile on the pfsense!

                From here it is a matter of choosing what interface you want to call it. Either OPT or WAN for your failover.
                So go to PPP and make your connection. Use your APN for T-Mobile and cuaU0.3 to connect, From there check your logs to see it connect or wait for it to acquire a DHCP address. It will show up on the dashboard.

                  My APN?  What is that and how do I find it?

                    It comes up under Interfaces>PPP
                    Use cuaU0.3. My screenshot is an example with no modem.

                      So you make your cellular interface under Interfaces>PPP connection from the tab and save. Then go to interfaces and add a new interface and use the PPP connection. You might want to research LAGG for the failover part.
                      Make sure you can connect first. Did you connect with FreeBSD/Ubuntu or Windows just to make sure the modem is OK?

                        I did not try in Windows as I do not know exactly how in Windows.  Is that with the Watcher?

                        Also here is the output for pfsense after configuring modem with T-Mobile in PPP.  Not working.  I have yet to receive my antenna so not sure if that will prevent this from moving forward but I would think it should get some type of signal.

                              Going to buy a GPS antenna also and see if I can get this to work.  This document shows the the GPS interface supports Active 3v antenna.  Looking to use this for NTP server.

                              My module shows that pfsense found 6 interfaces.  Interested if it will be easy to find which one it corresponds to.  Document shows how to activate power on GPS.

                                  I had gpsd working with my MC7700. On pfSense packages are limited so only some features from it work(no perl). xgps does work.

                                  No PPS so as a time server it is limited. Found it good for Arm with RTC modules keeping poor time.

                                  With AT commands you can set which antenna jack to use for GPS signal. So instead of using the dedicated GPS antenna jack you can set it to ANT2 and use the data antenna built into a laptop to receive GPS signal. The AT command is in the Extended AT Command Guide.

                                    I am wondering why you are trying to get the MC7700 going on T-Mobile.
                                    If you notice my post on the first page MC7700=ATT and MC7710=TMobile

                                    It should still work but I doubt it will get LTE. It will fall back to 3G in the 1900-2100 frequency range.
                                    MC7710 is more expensive. So much so you should consider the MC7354/MC7355 for TMobile.

                                      Just to add my understanding here, with the cm & em7455 and perhaps it matches with other models, is that they sell them with carrier approved firmware's with different product codes, however its all the same hardware so you can refresh with either generic of carrier specific firmware. I tried to get my EM7455 to register on ATT network using the carrier specific firmware and couldn't, I had to use generic and configure ATT settings to connect which i think has something to do with approved devices on the plan I am using. 
                                      Certainly the price for the Dell & Lenovo variations of the EM7455 is half the Sierra Wireless model (80usd vs 150usd) but they can easily be changed between variations as needed. The only pain is that on reset the Dell and Lenovo models revert to their original status codes and need reconfiguring. Once up and running, they are the same. Thats my current understanding.

                                        Just to add my understanding here, with the cm & em7455 and perhaps it matches with other models, is that they sell them with carrier approved firmware's with different product codes, however its all the same hardware so you can refresh with either generic of carrier specific firmware.

                                        Do you have step by step directions for how to do this?

                                          I am wondering why you are trying to get the MC7700 going on T-Mobile.
                                          If you notice my post on the first page MC7700=ATT and MC7710=TMobile

                                          It should still work but I doubt it will get LTE. It will fall back to 3G in the 1900-2100 frequency range.
                                          MC7710 is more expensive. So much so you should consider the MC7354/MC7355 for TMobile.

                                          The Cradlepoint IBR650-LP4 that I am using has a MC7700 and I am using with tmobile with ATT firmware and it has no problem with 4G or LTE speeds.

                                          http://www.comm2m.fr/images/produits/docs/Cradlepoint/CradlePoint_COR_IBR6x0__DataSheet_comM2M.pdf

                                          I ordered the wrong was do to a miscommunication that the IBR650 was Tmobile certified but it only has firmware for ATT and Verizon but we have had it in use for more than 2 weeks using tmobile sim and no issues.  Cradlepoint support said it would work.

                                            Should be receiving my antenna's today for LTE.  Have yet to order GPS Antenna.

                                            Question with regards to GPS.  I am not concerned about millisecond accuracy.  I am concerned with accuracy in the 30 second to 1 minute range.  I have fixtures with no real time clock and their programming needs to know what time it is.  If power goes out and internet does not come back I need to make sure they get accurate time but not millisecond timing.
