WE826 and MC7455 won't connect to eachother
Posted: Fri Oct 11, 2019 1:09 am
Hello,
new here but some assistance would be much appreciated. Running out of hair trying to get this up and running.
Just bought a new We826-T2 from The Wireless Haven, as well as some upgraded antennas and a used MC7455 from eBay in new condition. IMEI is clean. Using Verizon prepaid unlimited plan with a Novatel T1114 previously and wanted an upgrade and some more functionality. Received the modem and LTE card today and assembled everything following the tutorial. When it didn't immediately work I started reading the forums and trying many fixes from here but none have worked, including hard rebooting the device, factory resetting the device, reflashing the firmware, removing the SIM card and cleaning it, removing the LTE card and reinstalling it.
Some of the problem seems to be that I cannot run AT commands. The card will occasionally show as connected with an unknown IMEI and unknown SIM ICCID, but then it immediately disconnects. It has never once connected to the internet since I assembled it.
This is what it says under device information:

Which I'm assuming is the LTE card. Sorry for my naivety but I am extremely new to this hardware and UI so I don't know what other information might be helpful.
I have sanded the corners on my sim cards to make sure that wasn't the issue, and have tried my unlimited hotspot sim, as well as my unlimited phone sim with zero success.
Any help would be greatly appreciated. Thanks for reading!
