eSIM for China: What European Travellers Need to Know

China is the destination where sorting your phone out before departure matters most. It sits outside every European roaming agreement, the app ecosystem on the ground is not the one you use at home, and several of the things you would normally download on arrival are the things that are hardest to download once you are there. This guide covers what a travel eSIM for China gives you, what it cannot promise, and the order in which to set everything up.

Does EU roaming cover China?

No. The EU "roam like at home" rules cover 30 countries — the 27 member states plus Iceland, Liechtenstein and Norway — and China is not one of them. Your operator will bill mainland China at international rates, typically a daily bundle or a per-megabyte charge. Check your tariff's roaming zones before you fly.

The free-roaming area covers 30 countries in total: the 27 EU member states plus the three EEA countries. Everything beyond it, China included, is a commercial roaming arrangement between your operator and a foreign network, priced at retail margins on top. Some European operators sell world day-passes that make a long weekend survivable; across a two-week trip the daily charge adds up quickly, because every day on which you touch mobile data is billed in full. Look up China in your own price list first — that is the honest number against which to compare any alternative.

Which network does a travel eSIM use in China?

Every China plan in our catalogue runs on China Unicom, listed as a 5G network. There is no choice of carrier and none is needed — the eSIM profile carries its own settings, so there is nothing to configure. China Unicom is one of the three national mainland operators, with coverage across cities, high-speed rail and most tourist regions.

Because only one carrier is involved, there is no "which plan has better coverage" question to answer here. The difference between the twelve plans is data allowance and validity window, not network. Coverage is dense in Beijing, Shanghai, Guangzhou, Shenzhen, Xi'an and Chengdu, and holds up along the high-speed rail corridors; it thins out in mountain and desert regions, exactly as it does for a domestic subscriber.

Will Google, WhatsApp and Instagram work on a travel eSIM in China?

We cannot guarantee that any specific service will be reachable. A travel eSIM is a roaming connection, and roaming traffic commonly egresses the network outside mainland China, which is why many travellers find a roaming eSIM behaves differently from a domestic Chinese SIM. Routing can change, so install a VPN before you travel.

This is the question every traveller asks, and an honest answer has to be hedged. Mainland China filters internet access at the national level, and that filtering applies to traffic that stays inside the country. International roaming follows a different path: the data is carried over the local radio network but commonly leaves it through the home operator's gateway abroad. That is the technical reason a roaming eSIM often behaves differently from a prepaid SIM bought in a Chinese shop.

What it is not is a product feature anyone can sell you. Inter-carrier routing arrangements are not published, and they can change without notice. Plan the trip on the assumption that you will need a VPN, and treat it as a bonus if you do not.

Should I install a VPN before I travel to China?

Yes, and before you board rather than after you land. VPN provider websites and app-store listings are frequently unreachable from inside mainland China, so downloading, installing, signing in and testing at home is the only reliable order. Whatever you use, follow local rules on internet access while you are there.

The practical sequence is: choose a provider at home, install the app on every device you are bringing, sign in, and actually connect once to confirm the account works. Save the credentials somewhere you can reach offline and note the provider's support contact. Doing any part of this after you land is considerably harder, and app-store listings for these apps are not consistently available to mainland accounts.

How much data does a day in China really use?

Between 0.6 and 0.8 GB a day is the usual benchmark for ordinary travel use — maps, messaging, translation, ride-hailing, a few photos uploaded. China nudges that upwards for two reasons. Translation apps, including camera translation of menus and signs, run far more often than they do elsewhere, and QR-based payment means your phone needs to be online for routine transactions all day long. Budget around 1 GB a day if you expect to lean on translation heavily.

A VPN adds to that figure as well. The encryption overhead itself is modest, but a VPN left running all day keeps background sync alive over mobile data in moments when you would otherwise have been offline. On a metered plan, switch it off when you are not using it.

Hotel Wi-Fi is widely available and very often asks for a phone number and an SMS verification code, which is awkward if your number is on a line you have switched off. Keeping your home line active for SMS, with its data roaming disabled, avoids that trap at no cost.

What do eSIM plans for China cost?

Our China catalogue currently holds 12 plans, all on China Unicom. Metered plans run from €3.99 for 1 GB over 7 days to €35.99 for 20 GB over 30 days, with 5 GB over 30 days at €13.99. Unlimited plans start at €10.49 for three days. Treat every figure as indicative.

The full metered ladder runs €3.99 for 1 GB over 7 days, €6.99 for 2 GB over 15 days, €9.49 for 3 GB over 30 days, €13.99 for 5 GB over 30 days, €23.99 for 10 GB over 30 days and €35.99 for 20 GB over 30 days. Unlimited runs €10.49 for 3 days, €16.99 for 5 days, €24.49 for 7 days, €31.49 for 10 days, €43.99 for 15 days and €61.49 for 30 days. In sterling, the 1 GB plan starts at £2.99 and the 5 GB plan at £11.99.

Every figure above is indicative. The price table on this page is generated from live stock, so the number rendered there is the one that applies today — not the one that happened to be true when this guide was written.

Is an unlimited plan worth it for China?

For a sightseeing trip, usually not. The 5 GB plan at €13.99 covers a week comfortably at the normal benchmark, and 10 GB at €23.99 covers a fortnight with room to spare. Unlimited earns its price in a narrower set of cases: tethering a laptop, working while travelling, or running a VPN continuously across long days. Seven unlimited days cost €24.49, which is roughly what 10 GB over thirty days costs — so the choice is really between intensity and duration.

When should I install the eSIM for China?

Install it at home on Wi-Fi before you fly, and leave the profile switched off. Validity counts from first use — the first time the eSIM connects to a network — not from purchase, so installing early costs you no days. It also means you land already connected rather than troubleshooting at the airport.

Add the profile at home, give it a label you will recognise in a hurry, and leave it disabled. On landing, enable it, set it as your mobile data line, and switch data roaming off on your home line so no app quietly reconnects at international rates. Your home number stays reachable for calls and SMS throughout.

Which Chinese apps should I set up before I arrive?

Cash is genuinely awkward to use across much of urban China, and card acceptance outside hotels and large retailers is patchy. WeChat and Alipay both allow foreign cards to be registered, and completing that registration before departure — while verification messages and support pages are easy to reach — removes the single most common cause of a bad first day. Didi covers taxis and private hire; Baidu Maps and Amap cover navigation and work regardless of filtering.

Download offline maps for every city on your itinerary before you go. It takes ten minutes and eliminates the worst failure case, which is arriving without working navigation and without a straightforward way to fix it.

Do these plans cover Hong Kong and Macau?

The plans listed on this page carry coverage for mainland China. Hong Kong and Macau are separate jurisdictions with their own mobile networks and, in practice, their own and far less restricted internet conditions. Check the coverage list shown on any plan before assuming it travels with you across the boundary, and treat a Hong Kong leg as a separate connectivity decision.

Can I make calls with the eSIM?

No. These are data-only plans: they carry mobile data, with no voice minutes or SMS allowance. In practice this matters less than it sounds, because WeChat voice is the default way people call each other in China, and WhatsApp or FaceTime calls run over data wherever they are reachable. Keep your home line enabled for incoming calls and SMS codes, with its data roaming switched firmly off.

Will my phone work on China Unicom?

Your handset needs to be eSIM-capable and carrier-unlocked. Look for an "Add eSIM" or "Add data plan" entry in the settings before you buy anything; if it is not there, the phone cannot take an eSIM and no plan will change that. Band support is rarely the obstacle for a phone sold in Europe in recent years, and the profile configures itself once installed.
