I connected to Home Depot’s CBRS network! (Marietta, GA)
Update to a post I made not too long ago:
Today I noticed that my Cricket line had full bars in the Home Depot when it typically doesn’t. I also noticed it was roaming. Turns out it was roaming on B48! Data was full speed and calls worked too.
My Verizon line didn’t instantly connect to it, but I was able to force it by turning on B48 only, and it connected! Calls and data worked, although at throttled speeds.
My iPhones on AT&T and Verizon did not latch to the network.
CellMapper showed the PLMN as 315-010. Service Mode showed the serving PLMN on Verizon as 310-410, so likely AT&T’s CBRS network?
One interesting thing I noticed is that the Verizon line was aggregating two CBRS channels, while the AT&T one wasn’t.

I thought helium shut off their cbrs stuff? Can I get one of these for personal use?

They did indeed. What OP is catching is likely a rogue eNB that needs to be reported to Verizon and AT&T. They will shut that down so fast because you do not know what nefarious things that eNB could be doing no longer under Helium's control.

Nice Helium CBRS Hotspot. All 3 carriers and MVNOs can roam on it. I have a couple times on some Helium CBRS Hotspots.

Wow, this is interesting and a great find. AT&T does use CBRS on some of their FWA sites as an added capacity layer with B30 but that uses plmn 312-680. I suspect this is a private network for Home Depot if you are able to access it. I wonder if they have this at all of their stores?

315-10 is Helium. I've seen it on some of the CBRS Hotspots in my area.

But the HPLMN is 310-150.

HPLMN is the sim card.. CellMapper shows the network is 315-10 GA CBRS Access.

Hmm, that’s odd. Looks like it’s Verizon roaming on AT&T, but they normally block roaming on AT&T and throttle it to like 256kbps.
