Re: MC7455 and Visible by Verizon, Grammie help!

FIXED! Spent the better part of the day getting this up and running! Pulling 15-30mbps down, and 5-15mpbs up from the bottom floor of my house. All for 25 bucks a month since I'm taking advantage of the Party Pay. Reminder: Visible deprioritizes Visible customers when Verizon customers are active, AND the unthrottled bandwidth is offered for a limited time. I imagine my bandwidth could be greater or less depending on the time I test.

Note: Having both Skylight and Windows 10 managing the LTE connections leads to connection instability. Skylight will continually try to update/fix apn settings. Just uninstall Skylight and connect to MC7455, manually connect with Windows in the connection center. You will still want MC7455 drivers from the sierra wireless website.

This is for an MC7455 in a PCI adapter, with a Visible Verizon SIM, connected via USB to a windows 10 usb. Generic firmware installed on MC7455, most recent drivers installed from Sierra Wireless. I sent the commands using "My Huawei Terminal" but I believe you can send commands through putty as well.

AT! Commands for setup:

at!entercnd="A710" : Establishes admin access to Modem
at!usbcomp=1,1,1009 : sets MC7455 to MBIM mode, required for most interfaces (routers)
at+cgdcont=1,"IP","VSBLINTERNET" : sets APN as visble (seems that capitalization matters)
at+cgdcont=1,"IPV4V6","VSBLINTERNET" : allows for IPV4V6 use... this was a setting that seemed to "enable" my service.

The following commands associate verizon's/visible's bands with a name your MC7455 can use to pick specific bands to connect to. Visible uses verizon's 2, 4, 5, 13, and 66, but MC7455 doesn't support band 66.

at!band=0A,"B2",0,0000000000000002 : band 2 is now associated with 0A
at!band=0B,"B4",0,0000000000000008 : band 4 is now associated with 0B
at!band=0C,"B5",0,0000000000000010 : band 5....
at!band=0D,"B13",0,0000000000001000 : band 13...
at!band=0E,"VZW (All)",0,000000000000101A :notice the 101A, this is a binary representation of all the band values above.

Depending on your area, you can set the bands. If you only have band 2 for example, you can set: at!band=0A,
Just sub 0A, B, C, D, or E.

at!band=0E will enable your MC7455 to connect to any bands/aggregate them for better download speeds. I have this enabled in my area since I have all of the bands. NOTE: if you don't have all of the bands "associated" using the above codes, using the at!band=0E command above will not work because the binary number (101A) will be different.

Hope this helps someone

I updated the modem to the latest generic firmware and sent the AT command to allow for IPV4V6. I couldn't get Wireguard to work with Rooter, so I installed openWRT on the Raspberry Pi and then added the packages needed for QMI and Wireguard. This setup has been working fine with a Visible SIM card as long as I leave Wireguard connected. Without Wireguard, i lose connection after a few hours and I have to reboot. I have no idea why? I'm using the Raspberry Pi instead of the WE826GO-U that I put in the original post because it kept rebooting itself every few minutes. I probably did something wrong with the setup. I'm using the Sierra modem instead of the QUECTEL modem because I couldn't get QUECTEL to work with openWRT (it worked with Rooter).

on another thread I made an assertion that: On Verizon, you can't stick in any IMEI that's not "approved" on their network and have it work like you can on ATT/Tmo.

I have some supporting evidence to my assertion, for example: Quectel even has a guide on how to whitelist their devices on Verizon by working with Verizon.

Was this Quectel EP06-A that you used on Verizon ever officially registered by you with Verizon or could it have been done for you (for example, you purchased the EP06-A from a US Seller who registered it with Verizon before shipping it out)?

I would be interested in how successful people are on registering Quectel modems directly from China on Verizon

I've tried two MC7455, one works, the other does not. Visible does not work with a Telit LM940. Overall, I seen many more modems that fail to connect than ones that work. Try updating the latest firmware on the EP06-A, I've seen that work with other modems.
