China Mobile Data and eSIM Guide for Tourists
The complete guide to staying connected in China — eSIMs that bypass the Great Firewall (no VPN needed), VPN alternatives after the LetsVPN shutdown, and how to get a mainland phone number. Updated May 2026 with real traveler reports.
Key takeaway
Most tourists should arrange mobile data before landing. The simplest option: buy a data-only eSIM (Trip.com, Holafly, or Saily) before departure — these route through Hong Kong/Singapore and bypass China's firewall, no VPN needed. If you need a mainland phone number for app verification, get a physical SIM at the airport with your passport.
Full guide
Option 1: Data-only eSIM (recommended for most tourists)
An eSIM is a digital SIM you install before departure. It activates automatically when you land in China. Because these eSIMs route data through Hong Kong or Singapore, you get unrestricted internet without a VPN.
| Provider | Daily Data | Price (7 days) | VPN Needed? | User Feedback (May 2026) |
|---|---|---|---|---|
| Trip.com eSIM | 3 GB/day or "unlimited" (10 Mbps cap) | ~€12–17 | No | "0 problems" — highly recommended by multiple travelers |
| Holafly | Unlimited data | ~€19–27 | No | Reliable, integrated VPN routing |
| Saily | 1–5 GB/day plans | ~€7–15 | No | Good value, mixed speed reports |
| Superalink | Varies | ~€10–20 | No | ⚠️ Mixed — some say "works perfectly," others report "so many troubles." Support is WhatsApp-only (inaccessible without working internet in China) |
How to set up an eSIM
- Check compatibility: Your phone must be unlocked and support eSIM. iPhones XS and newer, recent Samsung Galaxy, and Google Pixel models all support it.
- Buy before departure: Purchase the eSIM 1–2 days before your flight. You'll receive a QR code by email or in-app.
- Install the eSIM: Scan the QR code in your phone's Settings → Cellular/Mobile → Add eSIM. Do this while still on your home WiFi.
- Wait to activate: The eSIM will connect automatically when you land in China. Do not turn it on early.
- Set as data line: On iPhone: Settings → Cellular → Cellular Data → select the eSIM. Keep your home SIM enabled for calls/SMS (disable data roaming to avoid charges).
Traveler tip: "I was scrolling Instagram and watching YouTube in my hotel room without toggling anything on or off." — Reddit user on Superalink eSIM, May 2026
Option 2: Physical SIM card (best if you need a +86 number)
A mainland Chinese phone number is useful for:
- Receiving SMS verification codes for restaurant ordering apps
- Registering on some Chinese platforms
- Getting contacted by Didi drivers or hotel staff
Where to buy
- Airport counters: China Mobile, China Unicom, and China Telecom all have service desks at major airports (PEK, PVG, CAN). Open during daytime hours.
- City carrier stores: Walk into any official store with your passport. Staff may not speak English — have a translator app ready.
- Trip.com / Klook: Some platforms sell tourist SIMs for pickup at the airport.
What you'll need
- Your passport (mandatory — they photograph it)
- Cash or Alipay/WeChat Pay for payment
- 15–30 minutes for the registration process
Typical costs
- 7-day tourist plan: ~¥100–200 (€13–26)
- 30-day plan with 20–30 GB: ~¥88–150 (€11–20)
- Plans usually include a mainland number and domestic calls
Option 3: VPN-only setup (fallback if eSIM isn't possible)
If your phone doesn't support eSIM and you can't get a local SIM, you'll need a VPN. Be warned: no VPN is guaranteed to work right now. The April 2026 GFW update was particularly aggressive.
VPNs reported working as of May 2026
| VPN | Platform | User Reports |
|---|---|---|
| Mullvad | iOS, Android, Windows, Mac | "Works well right now" — multiple confirmations |
| ZoogVPN (Shadow protocol) | iOS, Android, Windows | "Surprisingly solid" — tested in Shanghai during crackdown |
| Kiree VPN | iOS, Android | "Easy to use" — used as primary with V1 as backup |
| ProtonVPN | iOS, Android, Windows | Mixed reports; some say it works, others don't |
| Shadow Rocket + Vultr | iOS | Self-hosted — technical setup required, "cost nothing" |
VPNs that do NOT reliably work
- ExpressVPN: Slow on mobile, non-functional on Windows (May 2026)
- Surfshark: Similar issues — slow mobile, non-functional on desktop
- LetsVPN: ⚠️ Shut down mainland service April 2026, partially resumed but "not guaranteed"
Critical VPN tips
- Install and test before departure. Once in China, you can't download VPN apps from local app stores.
- Install at least 2 VPNs. If one fails, switch to the backup. This is not optional — VPNs go down randomly.
- VPNs do not work on airport WiFi. Wait until you're on mobile data or hotel WiFi.
- Desktop VPNs are harder. Many VPNs that work on mobile fail on Windows/Mac.
Step-by-step checklist before departure
- Check your phone supports eSIM (Settings → About → check for EID number)
- Confirm your phone is carrier-unlocked
- Decide: data-only eSIM or physical SIM with +86 number?
- Purchase eSIM 1–2 days before your flight
- Install eSIM on home WiFi (do not activate yet)
- Install at least 2 VPNs as backup (Mullvad + one other)
- Download offline maps for your destination city in Apple Maps or Google Maps
- Disable data roaming on your home SIM
- Save your hotel name and address in Chinese characters
- Screenshot your eSIM activation instructions (in case email doesn't load)
Who this is for
First-time and returning visitors to mainland China (1–30 day trips) who need reliable internet for maps, payments, ride-hailing, translation, and staying in touch with home.
How to do it
Check your phone supports eSIM and is carrier-unlocked
Decide: data-only eSIM (no VPN needed, no +86 number) or physical SIM (+86 number, passport registration required)
Purchase eSIM 1–2 days before departure (Trip.com, Holafly, or Saily recommended)
Install eSIM on home WiFi before your flight — do not activate early
Install at least 2 VPNs as backup (Mullvad + ZoogVPN/Kiree) even if using eSIM
Download offline maps and save hotel address in Chinese before departure
On arrival: eSIM auto-activates; if it fails, connect to airport WiFi and troubleshoot
Watch for
Waiting until arrival to figure out data — stuck with no service at the airport
Relying on a single VPN without backup — VPNs fail randomly after GFW updates
Not confirming eSIM compatibility before purchasing
Buying Superalink without a backup plan — multiple travelers report failures and WhatsApp-only support is inaccessible without working internet
Forgetting to disable home SIM data roaming — racking up hundreds in roaming charges
Assuming airport SIM counters are open for late-night arrivals — they typically close by 8 PM
What may vary
eSIM data speeds: 'Unlimited' plans typically throttle after daily cap. VPN reliability changes weekly with GFW updates — what works May 2026 may not work in June. eSIM firewall bypass may change if carriers alter routing. Local SIM registration rules vary by city and carrier. Airport SIM counter hours are not guaranteed, especially for late-night arrivals.
Backup plan
If your eSIM doesn't activate on arrival: connect to airport WiFi (passport scan required), contact the eSIM provider via email/app, or buy a physical SIM at an airport counter during daytime hours. If your VPN stops working: switch to your backup VPN immediately, or buy a data-only eSIM mid-trip using café/hotel WiFi.
FAQ
Do I really not need a VPN with an eSIM?
Confirmed by multiple travelers in May 2026: Trip.com, Holafly, and Saily eSIMs route data through Hong Kong or Singapore, giving unrestricted access to all Western services — no VPN required.
What if my phone doesn't support eSIM?
Buy a physical SIM at the airport or carrier store (passport required, 15–30 min), rent a portable WiFi hotspot, or use a VPN-only setup with at least 2 VPNs installed before departure.
Which eSIM is most reliable right now?
Trip.com eSIM has the most consistent positive feedback as of May 2026. Holafly is a close second. Avoid Superalink unless you have a backup — multiple users report arrival failures.
Should I keep my home SIM active?
Yes. Keep it in your phone with data roaming disabled for banking 2FA SMS, emergency calls, and app re-verification.
Can I use airport WiFi without a Chinese phone number?
Yes. Major airports (PEK, PVG, CAN, SZX) offer free WiFi. You'll need to scan your passport at a kiosk to get an access code. The process takes 2–3 minutes.
