"There has been an increasing focus on mobile network resilience following the winter storms of 2021/22"
That's all very fine and well but it's coverage I need!
I have, over the years, tried all of the networks starting with BT Cellnet/O2 then EE & now 3 who have merged with Vodafone so that's the full set!
Not one of them works with any reliability inside my house (brick & block construction, not thick stone walls) and I'm only 3 miles from the the M5 motorway & 4 miles from one of the largest construction sites in Europe a.k.a. Hinkley C Nuclear Power Station.
5G? Here? Don't make me laugh!
And I can still only get fttc with the cabinet being supplied from the local mains that was off for 4 days after those storms, though my power was only off for 1 day but with no internet or VoIP then.
PSTN should not be turned off untill there is 100% availability of emergency mobile access or ups backed VoIP.
