Three ways to get online: a roaming eSIM (easiest), a VPN (your backup for blocked Western apps), or a local SIM card (cheapest and fastest). Most travellers install a VPN before they fly and use an eSIM as the main connection.
Do this now: decide how you’ll connect before you board the plane. Once you’re in China, app stores block VPN apps and many provider sites are unreachable.
1 Choose your connection
Pick the setup that matches your trip. You can use more than one — many visitors run an eSIM as the primary line and keep a VPN installed as a fallback.
eSIM
Buy before you fly. Instant 5G, no app to install, and it slips past the firewall automatically. Best option for most travellers.
Read → ConnectivityVPN
Install at home to unblock Google, WhatsApp, YouTube and more. Keep one as a backup — it’s your lifeline to Western apps.
Read → ConnectivitySIM Card
Cheapest and fastest. Buy at any airport counter, get a Chinese number that apps like Didi expect, and pay only for what you use.
Read →2 The four options, compared
Most visitors only ever hear about “get an eSIM” or “buy a SIM at the airport.” In reality there are four distinct ways to get online in China, and they behave very differently once you land — especially for Western apps, SMS codes, and local services like Didi or food delivery. Here is the full picture before you buy anything.
What each option actually is
Physical Local SIM
A real-name +86 number from China Mobile, Unicom or Telecom. Uses the domestic network.
Data-only eSIM
Airalo, Holafly, Nomad and similar. Data only, no number, cross-border routing.
Numbered eSIM
TripoSIM, Ovosim and niche providers. A virtual roaming +86 number — not an official carrier number.
Official Carrier eSIM
China Mobile/Unicom/Telecom eSIM. Real +86, domestic routing. Rarely sold to tourists.

| Food delivery & bikes | Full | No Can’t register | High failure | Full |
| Buy & activate | After arrival; passport real-name; queue | Before departure; QR activate; no passport | Before departure; QR activate; no passport | Scarce for tourists |
| Device fit | Uses a SIM slot | Pure digital; no slot used | Pure digital; no slot used | eSIM phones only |
| 7-day price (USD) | $12–22 (airport markup) | $6–16 | $16–30 (premium) | Scarce, pricey |
| Hotspot tethering | Yes | Yes (check terms) | Yes | Yes |
| Main drawback | No Western apps; queue on arrival | No SMS; no public Wi-Fi | Unreliable codes; overstated marketing | Hard to buy; blocked apps |
Option A — Physical Local SIM
Best for: stays of 10+ days, no need for Western apps, and heavy use of food delivery or shared bikes. Not ideal for: 7-day trips that rely on WhatsApp to stay in touch.
Pros
- Real-name +86 number unlocks all local services
- Reliable SMS codes and public Wi-Fi login
- Best signal coverage in cities and scenic areas
Cons
- Google Maps, WhatsApp, Instagram blocked natively
- Queuing for registration right after landing
- Works only in mainland China; invalid after leaving
Option B — Data-only eSIM Top pick for 7-day trips
Cross-border routing means Western apps work with no VPN. Install before you fly and you’re online the moment you land.
Pros
- Western apps with no VPN
- Install before departure; instant on landing
- Low cost; trusted providers (Airalo, Holafly, Nomad)
- No risk of losing a physical SIM
Cons
- No phone number; no SMS codes
- Can’t log in to most free public Wi-Fi
- No cellular calls; internet voice only
Best combo for dual-SIM phones: keep your home SIM active (data roaming off, SMS only) + a data-only eSIM for mobile data.
Option C — Numbered International eSIM
Pros
- Only option with both a +86 number and Western apps
- Fully digital; no SIM swapping
- Can receive inbound local calls from hotels or drivers
Cons
- OTP risk for all major travel apps
- Often rejected by public Wi-Fi, bikes & delivery
- Much pricier than data-only eSIM
Only recommended for: single-eSIM devices with no SIM tray, where you accept the verification risk and stay logged in to all apps without signing out.
Option D — Official Carrier eSIM
Not recommended. Supply for overseas tourists is extremely limited, and it carries the exact same internet restrictions as a physical local SIM — with no real advantage.
Our pick for a 7-day trip
- Dual-SIM phone — top choice: Option B data-only eSIM + keep your home SIM active for SMS.
- Single eSIM device (no SIM slot): either go conservative with Option A (sacrifice Western apps for stable SMS), or take the risk route with Option C (keep Western apps, accept OTP failures).
There is no perfect connectivity plan. Every option involves unavoidable trade-offs — pick the one whose downsides you can live with.

Rather than scan the whole table, answer four questions and get a plan tailored to your phone and trip — including what to avoid and a setup timeline:
4 Quick recommendation
| If you… | Best choice |
|---|---|
| Want zero hassle for 1–2 weeks | Data-only eSIM (Airalo, Holafly, Nomad) — fast, cheap, no setup |
| Need Google / WhatsApp / YouTube | VPN installed before arrival (use alongside eSIM) |
| Stay a month+ or want a local number | Local SIM at the airport, VPN as backup |
| Everything else failed | Home data roaming — expensive, but always works |
Whichever you choose, install and test it at home. A connection you can’t verify before the flight is a connection you’ll regret at 2 a.m. in a new city.
