Mrs D's i-Phone doesn't pick up a proper signal in lots of locations in London (or so she tells me!).

Recommend from a yorkie with lots of cockney blood in him.
I make many trips to shows , TV recordings , rugby of course and so much more as well as relatives.

Its just so plain and easy , get a 24 hour travel pass . they are for 24 hours unlike up here when you have to bin it at 1am ish. Make sure you get under and over ground .
The guys at the stations or on the buses are fantastic.
It may be you need a underground then a bus for /3 stops on to a overground onto a bus onto a underground onto a bus for the best route . but they will save you a hours travel if you ask.

Hardly any Londoners drive into the square mile .

So simple advice 24 hour travel pass , plus its cheap really .

I always use my Oyster card.

Best way. Get one, keep it – and then put cash on it when you need it.

Much better than joining the crush at the ticket machines upon arrival at the Yorkshire Embassy (aka Kings Cross).

I'd not heard that one before.

talking of oyster cards, have something called a onepulse card been introduced? They were meant to be a combination of Barclaycard and oyster card. I used to work for the company responsible for the oyster card readers etc (cubic Transportation)

A similar idea to Mondex in Swindon? No.

To be honest, I have no idea. It was just something I read on their website about introducing it, was curious if it had actually happened. I do remember all the uproar when they were first introduced due to when a person scanned their card on the reader, (the system automatically trying to deduct the maximum amount for a journey) so was telling people you haven't got enough money on your card, so you can't come in!

Ah, there is an issue with NFC readers picking up cards in the same wallet as an Oyster card too so that would have delayed it, Those Oyser card wallets are so handy to keep nank cards in people have been doing it for years.

When I was sorting out the emissions controls for LTB I used to love working with Frankie Darch of London General. He was 30 years "on the buses" and what that bloke didn't know about how to get around the capital could be written on a postage stamp.

I'd be down there for a week at a time and the only time I used my car was in the middle of the night to move the specialist measuring and monitoring equipment from garage to garage. During the day I'd be chaperoned by Frank. Not only did he know which buses and tubes to use, he also knew all the back stairs and seret passageways at stations. I don't think we ever waited more than a minute for any connection to arrive.

When you get really sad you also know which carriage to get on that stops outside the exit of the station you're getting off at.

An aside, I nearly ended up working for London General, i went for an interview in Mitcham with the intention of working at Stockwell, i got a call through the interview which was embarrassing but i let it ring through to voicemail. You found out the same day if you were successful, so they told me to wait in a room while they deliberated, i called my voicemail and it was a job offer, so i just walked out and i'll never know if i got it of not.

I reckon most regular travellers on their daily commute know which carriage to get on at.
It makes sense to use a bit of your waiting time to put yourself at the spot on the platform where that carriage will arrive, thereby saving time that would be spent at the other end shoving through the tide to get to the exit.
It's when people know a lot of "where to wait" that it's maybe getting a bit sad.

And I have a few favourites myself.

Waterloo to Kings Cross.
Take the Bakerloo Line Northbound, get on in the middle of the train, change at Oxford Circus, just straight through the short corridor to the parallel platform which is Victoria Northbound (no stairs or tediously long tunnels to negotiate).
When you get to KX, don't follow the sign for KX Mainline trains but follow the exit sign for Euston Road.
Once through the ticket barriers turn right, short walk and then first right again up the steps into the corner of the old concourse, then nip across the unbarriered corner into the new concourse.

When arriving at KX and wanting the Victoria Line, go down the steps from the old concourse (which is where you arrive) and IGNORE the sign pointing right to the Victoria Line, instead go left, short walk and then left down a few steps and through the ticket barriers.

Both of these save what feels like miles of walking through tunnels.

It's similar with buses too, sometimes it can be quicker to catch 3 buses than one direct bus.
I know the network like the back of my hand north of the river from as far west as Hayes and far east as Tottenham.

Funny thing i used to do when i worked at Brent X, if people asked me how to get to Archway, the tone and manner in which they asked depended on the answer i gave. There are 3 buses with the quickest being 30mins and the longest 1h 5mins

Except for a small handful, bus routes are a big gap in my London knowledge.
If I have the time, I do love jumping on one just to see the route it takes, not just in London come to that.
Is that strange? Oh well.
