Wireless Joint

So I have two modems an EM12 and an EM20 both on WE826GO routers.

Just recently they both can no longer connect to anything 4g. Once I set the Cellular mode to Auto then I can connect to a cell. It doesn't say what mode it is

AT+QNWINFO
+QNWINFO: "HSPA+","310410","WCDMA 850",4385

its really slow and up until this week I could point to a couple 4G cells now nothing with both.

Not sure what's going on , I made no other changes to the setup.

I'm wondering if the tower is just down , if that happens for extended periods, or they are changing to 5g or something.

Its been working fine here for several years and I got very knowledgeable with what cell is the good one.

Thoughts?

I have had the sprint tower near me go down for 4-5days. For the first couple days they couldn't get the key to the gate that let them onto private property and then it took a few days to fix the problem. Anyway when I loose reception like that I just call my provider and see they have any issues with towers in my area.
