London's second airport: two terminals on opposite sides, a short train ride in, and a choice of city stations at the end of it.
Switch the data line on at touchdown, then work out whether you are in the North or the South terminal, because their railway stations are not the same place and getting it wrong means riding the shuttle back. The walk from gate to border is noticeably shorter than at Heathrow, though several aircraft landing together can still build a queue. If you arrive late in the evening, check the last train before you leave the arrivals hall: the night timetable thins out, and switching to a car at that hour changes both the time and the cost of the trip. Once you are through, the signs lead straight to the station, only a few minutes further on.

Gatwick sits south of London and handles mostly medium-haul and low-cost traffic, so travellers from Asia usually meet it on a European connection rather than on the long flight in. It has two clearly separate terminals joined by an automated shuttle rather than a corridor. Compared with Heathrow the scale is immediately smaller and the walk from aircraft to baggage hall shorter. What you give up is choice: getting into London from here is essentially a train decision.

The airport Wi-Fi is free once you have cleared a sign-in page, and inside the building it is enough to check a flight or send a message. Where it stops being useful is the platform and the train itself, which are no longer airport territory: the signal is gone before the doors close. The run into London crosses stretches of southern countryside where mobile coverage dips and recovers, so the leg that matters most is the leg Wi-Fi cannot help with. Anyone who has watched a ticket barcode refuse to load while a train pulls in knows the feeling. A line that came up on landing removes the whole problem.
The express train from Gatwick reaches Victoria in about half an hour, while the slightly slower ordinary services run to London Bridge and other stops on the same north-south spine, some of which land closer to where you are sleeping. Choose the terminus by your address, not by the word express. Tickets now mostly live on a phone, so you need data at the barrier to show a code, which is why people worry more about battery than about getting lost. On board the only data you spend is a map, a timetable app and a message saying when you will arrive. If the plan after London is a train under the Channel to the continent, check in advance whether what you are carrying covers the far side or whether that leg needs its own arrangement.

It is south of the city; the express reaches Victoria in roughly half an hour, while a car takes longer and swings with the traffic.
Night services thin out and change with the season, so check the last departure in a timetable app while you are still inside the terminal and decide from there.
It depends on whether what you are already carrying lists the United Kingdom. If it does, the same line picks up a British network on landing; if it does not, this side needs its own arrangement.
Mostly usable, with dips as the line crosses open country, so book an onward car or open your map before the train pulls out rather than halfway along.
