A related effort is the NYC MTA's 10-year project to bring cell connectivity to subway tunnels (not just stations). You can already experience this if you take the L from Manhattan to Brooklyn: you will have continuous cell connectivity from the First Ave station to the Bedford Ave station. https://new.mta.info/press-release/mta-announces-universal-s...

It's not clear from the article whether the Underground is trying to add between-station cell coverage?

There is between station coverage. On the northern line I have been in-tunnel and got a solid full-signal 5g with 130mbps on speed.cloudflare.com tests for example.

My phone is dead from Kennington to Tooting Bec. Does it differ by telco provider?

Which provider? I don't get such speeds anywhere in London with O2
