Traveling to China? Why Half Your Apps Won't Work and What To Do
In mainland China, Google, Gmail, Google Maps, WhatsApp, Instagram, Facebook and YouTube do not work on local networks or hotel WiFi. What decides whether they work for you is not which apps you have installed but where your data exits onto the internet. A local Chinese SIM exits inside China and gets filtered. An international roaming eSIM tunnels your traffic out to a partner network abroad, which is why travellers on one keep using their normal apps. Install everything before you fly, because the Chinese App Store won't have half of it.
Most first trips to China go the same way. You land at Pudong or Beijing Capital, clear immigration, open Google Maps, and watch it spin. WhatsApp stops delivering. Instagram won't load. It feels like the phone is broken, and it isn't. You're simply on the wrong kind of connection, and the fix is something you had to do before you boarded.
What actually stops working
The filtering system, officially the Golden Shield Project and known everywhere else as the Great Firewall, inspects traffic crossing between Chinese networks and the outside internet. The blocked list shifts, but the pattern is stable enough to plan around.
| Blocked on Chinese networks | Works normally |
|---|---|
| Google Search, Gmail, Google Maps, Drive, Photos | WeChat, Alipay, Didi, Baidu Maps, Amap |
| WhatsApp, Instagram, Facebook, Messenger | Trip.com, Ctrip, Meituan, Dianping |
| YouTube, X, Netflix, Spotify | Apple services, iMessage and FaceTime in most cases |
| Many Western news sites | Most banking and airline apps |
The rule of thumb for 2026: if Google or Meta built it, assume it will not load on a Chinese connection.
Why a roaming eSIM behaves differently
This is the part worth understanding, because it explains every recommendation that follows.
The firewall can only filter traffic that travels through mainland Chinese infrastructure. When you use a local Chinese SIM, your data exits to the internet inside China and passes through those inspection points. When you use an international roaming eSIM, your phone still authenticates to a Chinese cell tower, but your internet traffic is tunnelled back to a partner network outside the mainland, commonly Hong Kong or Singapore, and exits there. You're standing in Shanghai while your connection's exit point sits outside the country.
That difference is why travellers on a roaming plan open Google Maps at baggage claim and it simply works, while the person beside them with a local SIM cannot. Routing varies by provider and plan, so confirm it before you buy rather than assuming.
Install everything before you fly
This is the mistake that compounds. Many international apps are unavailable in the Chinese App Store and Google Play is not present on Android devices there at all. If you land without an app, you may not be able to get it.
- WeChat. Not optional. It's messaging, payments, taxis, restaurant menus and ticketing in one. Set it up and verify it in India, since verification sometimes needs an existing user to vouch for you
- Alipay. The other half of the payment system, and it accepts foreign cards in tourist mode. Link your card before departure
- Didi. The ride-hailing app, with an English interface. There is no Uber
- Amap or Baidu Maps. Chinese mapping apps are far more accurate on the ground than foreign ones, and they work regardless of routing
- Offline translation. Download the offline Chinese language pack in whichever translation app you use. Google Translate's app was withdrawn from mainland China in 2022
- Offline maps for every city on your route, downloaded at home
You cannot afford to be offline in China
China runs closer to cashless than almost anywhere. Street stalls, metro gates, museums and taxis all expect a QR code, and both major payment apps need a live data connection to generate one. Cash is still legal tender and small vendors will sometimes struggle to make change for it.
So connectivity in China isn't a convenience the way it is on a beach holiday. It's how you pay for lunch. That's the argument for having a working plan installed before you land rather than hoping to sort it at the airport.
One eSIM, three different internets
Hong Kong and Macau are separate jurisdictions with their own networks and no Great Firewall. A single China, Hong Kong and Macau eSIM covers all three on one profile, which matters because a Greater Bay Area trip crosses between them repeatedly.
Practically, this means your apps behave differently depending on which side of the boundary you're standing on if you're using local connections. On a roaming plan the experience stays consistent, which is the point of buying one profile rather than three.
Plans and prices
The Matrix plan runs across China Unicom, SmarTone and CTM, covering the mainland, Hong Kong and Macau on one profile at 5G, 4G or LTE.
| Detail | What it means |
|---|---|
| From ₹599 | Tiers run from 1 GB to 20 GB, plus unlimited options |
| 7 to 28 day validity | Match it to the trip. Most China itineraries run 8 to 14 days |
| Fair usage on unlimited | 3 GB a day at full speed, then 128 kbps for the rest of that day |
| Hotspot | Allowed on the limited-data plans only, not on unlimited |
| No phone number | Data only. No incoming calls, so keep your Indian SIM live for anything dialable |
| KYC required | Per DOT guidelines, so allow time rather than buying the night before |
On sizing, 128 kbps after the daily cap is slow enough to matter. If you're travelling with someone and planning to tether, take a fixed-data plan instead, since hotspot is restricted on unlimited.
About iPhones and eSIM in China
You may have read that iPhones don't support eSIM in China. That refers to handsets bought in mainland China, which ship with two physical SIM slots instead. An iPhone bought in India works normally. Check yours the usual way: dial *#06# and look for an EID.
Before you fly
| Do this | Why |
|---|---|
| Install and verify WeChat and Alipay, and link a card | You'll struggle to pay for anything otherwise, and you can't download them there |
| Install Didi, Amap and your translation app with offline packs | Same reason. The app stores are filtered too |
| Buy the eSIM early enough for KYC to clear | Not a night-before purchase |
| Install on home WiFi and confirm the EID first | Installation needs a stable connection |
| Turn data roaming ON for the eSIM, OFF for your Indian line | A roaming eSIM needs that toggle on, or you get signal and no data |
| Download offline maps for every city on the route | Covers you in metros, tunnels and the first hour after landing |
| Tell family which app you'll actually be reachable on | Worth agreeing before you're in the air |
Sort it before you board
China is the one destination where arriving unprepared genuinely doesn't work. Install the apps, buy the plan, clear KYC, and land with a phone that behaves the way you expect.

Frequently asked questions
Does WhatsApp work in China?
Not on Chinese networks or hotel WiFi, where it has been restricted since 2017. It does work for travellers whose data is routed outside the mainland, which is how international roaming eSIMs operate. Confirm the routing with your provider before you buy, and tell family in advance which app you'll be reachable on.
Does an eSIM get around the Great Firewall?
An international roaming eSIM usually does, because the filtering only applies to traffic passing through mainland Chinese infrastructure. Roaming data is tunnelled out to a partner network abroad and exits there. An eSIM sold by a Chinese carrier does not, since it sits behind the firewall exactly like a local SIM.
Do I need a VPN in China?
Unauthorised VPN services are illegal in China and authorities have warned publicly about using them to bypass the firewall. They're also unreliable, since the filtering detects VPN traffic and you can't download a replacement once you're inside the country. Ordinary international roaming data avoids the issue.
Will Google Maps work?
Not on a local connection. Even on a roaming plan, Chinese apps such as Amap and Baidu Maps are more accurate on the ground for navigation, transit and business listings. Install one before you fly and keep Google Maps as a backup.
Can I download apps after I land?
Often not. Many international apps are unavailable in the Chinese App Store and Google Play isn't present on Android devices there. Install WeChat, Alipay, Didi, maps and translation before you leave India.
How do I pay for things?
WeChat Pay and Alipay, which now accept foreign cards in tourist mode. Both need a live data connection to generate the QR code, which is why connectivity in China is closer to a necessity than a convenience. Carry some cash as a backup, though small vendors may struggle with change.
Does one plan cover Hong Kong and Macau too?
Yes. The China, Hong Kong and Macau eSIM covers all three on a single profile, which suits a Greater Bay Area itinerary. Both Hong Kong and Macau are separate jurisdictions without the mainland's filtering.
Can I get a Chinese phone number?
Not with this plan, which is data only with no incoming calls. Keep your Indian SIM in the phone for anything that needs a dialable number, and use WeChat for day-to-day contact, which is what everyone in China uses anyway.
How much data do I need?
Around 10 GB for a typical ten-day trip, since you'll lean on maps and payment apps constantly. Unlimited plans give 3 GB a day at full speed before dropping to 128 kbps, so take a fixed-data plan if you're tethering, which unlimited doesn't allow.
My iPhone says eSIM isn't supported in China. What's going on?
That applies to iPhones bought in mainland China, which ship with two physical SIM slots rather than eSIM support. An iPhone purchased in India works normally. Dial *#06# and look for an EID to confirm.
