For seven days from 1 October 2026, most of China is off work at the same time. National Day Golden Week is the country's second great travel wave after Spring Festival, and the numbers are hard to picture: the 2025 holiday recorded 888 million domestic trips over eight days, up from 765 million across the seven-day 2024 break. A seven-day 2026 holiday somewhere in that range still means hundreds of millions of people booking, boarding and queueing in the same week you are.
If you're travelling to China that week, the connectivity question changes shape. The usual China article is about which apps load — we've written those, and they still apply. This one is about capacity: in Golden Week, almost everything that saves you time is booked in an app, and a slot you can't book is a slot you don't get.
The shape of the week
The holiday runs Thursday 1 October to Wednesday 7 October. The State Council's 2026 calendar also designates Sunday 20 September and Saturday 10 October as working days, which pushes the outbound rush into the evening of 30 September and the return into the weekend after. Unlike 2025, Mid-Autumn Festival (25–27 September) falls separately this year, so there are effectively two waves rather than one eight-day megabreak.
Practical read: the first and last days are the worst for stations and airports, and the middle of the week is when headline sites are fullest.
Everything that saves you time is an app
Three systems matter, and all three are app-first:
- Timed-entry tickets. Major museums and monuments run real-name, timed-slot booking — you reserve online in advance with the passport you'll present at the gate. Daily quotas are finite, released a set number of days ahead, and in Golden Week the good slots for the famous sites are gone early in the day they open.
- Transport. High-speed rail is sold through the national ticketing system on a fixed advance window (15 days at the time of writing, though it has changed before), and Golden Week departures sell out in minutes. Foreign passports can be registered directly; the passport is then the ticket at the gate. Account verification can take days if the automatic check fails on your name, so do it before you leave.
- Payment and getting around. Ride-hailing, mobile payment, metro QR codes, restaurant ordering — all normal, all on your phone, all useless without data at the moment you need them.
None of that works from a queue with no connection. A slot booked for 09:30 cannot be booked at 09:25 on a dead phone, and the refund and rebooking that follow are also in an app.
Why arriving already connected matters more this week
In a normal week, sorting out data after you land costs you an afternoon. In Golden Week it can cost you the trip's headline booking, because a local SIM means a passport-registration queue at a carrier shop during the busiest travel period of the year — and the queue is longer precisely when the tickets are moving fastest.
A VamosData eSIM for mainland China avoids that trade-off entirely: install it at home on good Wi-Fi, and your data is live when you switch off flight mode. Your normal SIM stays in the phone for calls and bank SMS while your VamosData eSIM handles the booking apps. And because it routes your traffic through a gateway outside the mainland, the maps and messaging apps you already use behave the way they do everywhere else — which is the subject of our other China posts rather than this one.

A pre-flight checklist for Golden Week
- Check your phone supports eSIM with the device checker — and check carefully if you bought it in mainland China.
- Buy and install your VamosData eSIM before you fly, following the iOS or Android guide. Browse the China plans.
- Register your rail and ticketing accounts early, while manual passport verification still has time to clear.
- Book the timed-entry sites the day their quota opens, not the day you want to visit.
- Screenshot every booking confirmation and QR code, so a bad signal in a crowd doesn't cost you an entry slot.
- Download offline maps for each city, as the belt-and-braces backup.
The honest limits
Two things no SIM fixes. The moment you join hotel or café Wi-Fi you're on a local connection again, with local rules, whichever SIM is in the phone. And a national holiday puts extraordinary load on the networks themselves: at a packed site or a station concourse at peak hour, everyone around you is uploading too, and it will feel like it.
Neither is a reason to arrive unprepared. It's a reason to have the bookings made, the confirmations saved, and the data already working before the plane doors open.
