I gave this the "mystery shopper" treatment at Westminster and all

Saturday: Finsbury Park to Vauxhall, Victoria line
FP: no signal

KX-Victoria, in stations: connected to wifi, but VM landing page said
'something went wrong, make sure cookies are enabled on your phone'. Didn't
do anything else (needless to say, they were enabled)

Can't remember if there was any signal south of Victoria.

Sunday:
Waterloo Bakerloo corridor: no signal

Northern line Waterloo northbound platform:
successfully received login page, signed up, no problems, could see Google

Waterloo-Tottenham Court Road, Northern Line stations:
Connected OK, but couldn't connect to websites

Tottenham Court Road to Bank, Central Line.
Worked fine in stations.


So not quite 'nul points', but not terribly useful. On Android the time
from emerging from the tunnel to rescanning and connecting is about 70% of
the dwell time in the station - you have about 15-20s of doors closing and
pulling out of the station before the signal goes again. When it worked it
was enough to check train times (with a pre-entered URL - eg
traintimes.org.uk/kgx/edb ) but not much that requires interaction.
