Anyone else unable to call landlines from an O2 sim?
The mobile networks are under more strain at the moment due to more people working remotely, so it may just be related to that.
That's interesting - I was considering getting my next phone from Giffgaff, but I might reconsider! That sounds annoying.
I use Giffgaff, which operates on the O2 network. More often than not, calls to landlines drop without even a ring. I have a secondary phone, which uses Vodafone. I use it if the main phone doesn't work.
Mine seemed okay yesterday (haven't tried today).
