Three/SMARTY Band 20 gone over the weekend. Checked using LTE discovery, mast no change, still getting a decent speed, up to 70Mb/s. No maintenance posted on the website. Bit of a puzzle.
MBNL mast, smells of backhaul failure.We had an outage on Saturday. I don't think it was only B20 though because when I put the SIM in my phone it didn't pick up anything, even when I moved to clear sight of a B3 mast. Interestingly it corresponded to an outage on EE as well, but O2 was OK. So that's a bit odd, a fault affecting two masts and two carriers. Unless it was a coincidence of course.
It seems like its telling you the layers available and connected but would be hard to determine as the device has two sims in it and also seems to be bouncing on and off 3G.
