Hello,
Just installed a Dome PRO LR on my building with a SIM injector and SDX PRO. I have T-Mobile SIMs and ATT SIM in the SIM injector.
There are no issues connecting to T-Mobile 5G, but ATT will only connect to LTE.
When I restrict the bands to only 5G the SIM never connects to ATT
I am seeing the same thing on my BR2, which is a mobile setup.
Hey Michael!
Happy Thanksgiving!
Are you using the same plan in both?
Is the cellular module the same in both?
If you send me an e-mail I can look at it after I have my turkey lunch

I emailed my ATT rep and she said the sims are 5G plans but I have no other way to confirm.
Well, my BR2 called me a liar. I just plugged in and upgraded to the latest firmware, and now it is powered up and connected to 5G.
Guess I could try to upgrade the LR to the same firmware and see if that fixes it.
Upgraded my SDX PRO and Dome LR and now it connects to ATT 5G. Though max speeds are only around 10-15Mbps download.
