Hi, this is very strange.

I've been using cellular modems and routers for a long time and am experimenting with Quectel RM551E-GL modems.

In my Cambridge area, up until about two weeks ago I got about 800 MBit/s download on 5G-NSA.

I was connected on 5 bands - B3 primary, B3 secondary 1, B1 secondary 2, and two n78 bands.

However, B1 disappeared about two weeks ago and I only got 4 band connection, and my download speed literally halved, to 400 MBit/s.

I can't see B1 on EE anywhere in Cambridge, either on a router/cellular modem or on my phone (Fold 6). Can anyone shed any light on this? (If I change to a 3 sim, I get B1 connection so it's not an issue with my devices)

Thanks!

Something else awry then. Are you familiar enough with the radio stack and a suitable app, to identify the carrier/EARFCN in use when you have issues, and following the toggle?
