Travelling in the busiest movement week of the year

The period is not the same in every country

Lunar New Year is the holiday when enormous numbers of people travel back to their home towns, and its effect on travel depends on where you are. In mainland China it is the largest movement of people in the year, with domestic rail and air tickets selling out far ahead. Taiwan and Hong Kong have consecutive holidays and a lot of outbound travel. In Singapore and Malaysia there are fewer public holiday days, but many shops and services close for several. The exact dates everywhere follow the lunar calendar and each government's announcement, so they change every year.

What matters for preparing the phone is that two countries two hours' flight apart can be entirely different in terms of which apps are reachable. So if your trip crosses between mainland China and elsewhere in the region, prepare for two different environments, not one.

How mainland China differs

In mainland China a number of internet services familiar to overseas travellers may not be reachable, including some map apps, chat apps and email services. What is reachable changes over time and we will not claim to know the current state on your behalf. What you can actually do is prepare fallbacks in advance: download offline maps, save your accommodation address in Chinese, and agree with people at home which channel you will use to stay in touch.

• Download offline maps for every city you will visit, before you leave
• Save the accommodation address in Chinese as an image, in case a translation app is unavailable
• Agree a contact channel with people at home in advance and test it before flying
• Keep travel documents offline — tickets and accommodation bookings alike
• If you plan to use a VPN, check the applicable laws and terms for yourself first

Preparing step by step

1. 1Before fixing dates: check the destination's holidaysThe date moves every year and each country's public holidays differ. Read that country's official holiday announcement rather than going by last year.
2. 2Weeks ahead: book domestic transportDomestic rail and air tickets go fast in this period. Book through the operator's official channels and save the confirmations offline.
3. 3Before flying: install the eSIM and test everything at homeInstall the profile on Wi-Fi, set it as the data line, and test that the app you intend to use to reach home actually works on this device.
4. 4Before flying: download everything you will needOffline maps, translation language packs, the accommodation address and booking confirmations should all be on the device before you board.
5. 5On arrival: confirm you are connected before leaving the airportLet the phone register on the network and check that maps and messaging work before heading out to a packed station where sorting problems out is hard.

If data starts running short mid-trip

The Lunar New Year period tends to burn more data than planned, because plans change at short notice more often than on an ordinary trip — a train ticket that could not be booked in time, a shop that closed with no notice. Each time you have to find an alternative you reopen a search app and a maps app several times over. If you notice data dropping faster than expected mid-trip, check the real usage figure in the operator's app straight away rather than waiting to see if it lasts. If you are still somewhere with good signal, topping up on the road is far easier than waiting until you need an emergency room booked with no connection to help you.

Fairs and night markets crowded during the festival

Many cities in the region hold fairs, night markets or fireworks displays over Lunar New Year, drawing large crowds into one district for several nights running. What happens to the network there resembles a big festival ground anywhere: the channel fills before anyone notices, especially in the minutes before fireworks start and right after they end, when everyone tries to film and send at once. If you plan to visit, agree a meeting point with your group before entering the crowd, and do not rely on calling each other the moment the fireworks finish — that is exactly when everyone nearby is doing the same thing at once.

Common sizing mistakes for this trip

The most common mistake is budgeting the same as an ordinary regional trip, forgetting that if the route touches mainland China, working out fallback maps and contact methods costs more time and data than simply opening the app you are used to. Another is not separating the data needs of each country on a single trip, when mainland China, Hong Kong, Taiwan, Singapore and Malaysia behave so differently, as described above. Averaging across the whole trip tends to be more inaccurate here than for an ordinary one.

Travelling home for reunion, at the busiest stations of the year

Lunar New Year is not only a travel season; it is the single largest simultaneous mass movement of people back to their hometowns anywhere in the year. Major rail and bus stations in several cities become more congested than a stadium or a festival ground, because the crush is not confined to a few hours but runs for days on either side of the holiday itself. If your trip involves passing through these stations at peak times, allow extra time for every kind of app to lag, not just maps — from scanning a digital ticket to the identity verification some stations require through an app.

• Screenshot or pre-load the digital ticket in advance; do not rely on the app loading live at the gate
• If a station requires app-based identity verification, do it while still somewhere with normal signal, not while standing in the long queue
• Families travelling together should agree a meeting point inside the station in advance; finding each other in a crowd this size by phone alone is usually too slow

Digital red envelopes and transfer apps during the festival

Many families in the region have shifted at least part of the red-envelope tradition onto transfer apps, which looks like it should use almost no data since it is only a number. In practice it tends to happen all at once when relatives gather for a meal, with everyone in the same house or restaurant leaning on the same Wi-Fi or mobile network at the same moment. If that location already has a weak network — a relative's home in the suburbs or in a smaller town — transfers can hang or lag more than expected. The safe move is to test the transfer app and confirm the linked bank account is tied to a number that still works, before the reunion meal rather than while everyone is waiting at the table.

Visiting several cities in one trip, and how differently each behaves

A Lunar New Year trip touching several cities in the region often mixes places with very different levels of network infrastructure. A major hub like Hong Kong or Singapore has high capacity and generally copes well through the festival, while a secondary city in mainland China or Malaysia can have far more limited capacity, especially when locals working in bigger cities return home to visit family at exactly the same time you are passing through. Planning connectivity the same way for every city on the trip tends to be less accurate than looking at each one on its own terms.

Flower markets and new year night markets that pack out at certain hours only

Flower markets and pre-new-year night markets in many cities are not equally packed all day; they spike hard in the evening and late into the night before Lunar New Year's Eve itself, when locals turn out in large numbers within a few hours to buy offerings and flowers together. If you are visiting as a tourist to take photos or soak up the atmosphere, going in the afternoon before the crowd builds usually gets both easier photos and a much smoother network than going at night. If evening is the only option, expect map loading and photo sharing to run slower than usual during each night's peak.

Sending a large batch of new year greeting messages on the eve itself

The tradition of sending new year greetings to dozens of relatives and friends at once on the eve itself is still common in many families, and when a large number of people in the same area do this within the same few minutes around midnight, some messaging apps can slow down temporarily even though the wider network is not much worse overall. What helps is preparing the message and any photos in the app well before midnight rather than typing them live at that moment, so you can hit send right away instead of typing during the network's busiest few minutes of the entire year.

Paying digital red packets through an app, and the trouble that shows up when signal is unsteady

Sending digital red packets through a transfer app is becoming more common than physical red envelopes in many families, especially when relatives live in different cities, but a transfer like this needs a reasonably steady network throughout the identity-check and confirmation steps. If signal is unsteady partway through, the transaction can sit in an unclear state where it is not obvious whether it went through, which causes more worry than an ordinary transfer would, since it involves an elder relative on an important day. The safer approach is waiting until the network feels steady before confirming the transfer, rather than rushing it through in a crowded spot with unreliable signal.
