Just to clarify - coverage will only extend to the W&C platforms at
Waterloo and Bank, there won't be coverage when the train is in the
tunnel - i.e. when passengers are on a train that isn't in a station.

I suggest you read the article again:

"Coverage will also extend to tunnels between the two stations. This
means that passengers will be able to use their mobile phone and other
handheld devices while travelling on the Waterloo & City line."
