On Arrival

From customs to connected at Beijing Capital (PEK) / Pudong (PVG) / Daxing (PKX)

When to turn on your eSIM

Activate your eSIM after clearing customs at Beijing Capital (PEK) / Pudong (PVG) / Daxing (PKX), before you leave the terminal. Do not enable it during a layover at a connecting airport. Most plans start counting from the first network connection, not from installation. Enabling during transit burns a full day of your plan.

Connecting to China Mobile's network

  1. Open Settings on your phone
  2. Go to Cellular (iPhone) or Network & Internet (Android)
  3. Select your travel eSIM line
  4. Enable Data Roaming on that line only
  5. Wait 2-3 minutes for China Mobile's 5G network to register

Expected speeds on China Mobile: approximately 180 Mbps download.

Airport WiFi as backup

Beijing Capital (PEK) / Pudong (PVG) / Daxing (PKX) offers reliable free WiFi. Use it as a backup to complete eSIM installation if you did not set up at home. Airport WiFi often requires a phone number to register, so installing at home is the safer option.

What if your eSIM does not connect

  1. Toggle Data Roaming off and back on
  2. Restart your phone
  3. Verify the travel eSIM is selected as your cellular data line
  4. Try manual network selection: choose China Mobile
  5. For emergencies, dial 110/120/119

Configuration

Configuring your phone for China

Dual-SIM configuration

Keep your home SIM for calls and texts. Set the travel eSIM as your cellular data line. On iPhone: Settings > Cellular > Cellular Data > select travel eSIM. On Android: Settings > Network & Internet > SIMs > set travel eSIM for mobile data. iMessage and FaceTime should stay on your home number.

Data roaming settings

Enable data roaming on the travel eSIM line only. Disable data roaming on your home SIM to prevent carrier charges. On iPhone: Settings > Cellular > select home SIM > Data Roaming OFF. On Android: Settings > Network > SIMs > home SIM > Roaming OFF.

APN configuration

Most eSIMs auto-configure APN settings for China Mobile. Verify in Settings > Cellular > Cellular Data Options > Cellular Data Network. If auto-configuration fails, check your provider's email for manual APN values. Manual entry is rare but occasionally needed on older Android devices.

Troubleshooting

Troubleshooting your China eSIM

VPN and internet restrictions

VPN services are blocked in China. Government-level filtering prevents most commercial VPN protocols from connecting. Great Firewall blocks most VPN services; only government-approved VPNs technically legal; travelers should install VPN before arrival Downloading VPN apps inside the country may also be restricted — app stores can remove listings based on geographic IP. Install and configure your VPN before departure. Test it over home WiFi to confirm it connects. Some travelers report that certain protocols (WireGuard, Shadowsocks) work intermittently, but reliability is not guaranteed. If you rely on VPN for corporate access, discuss alternatives with your IT team before traveling. A prepaid eSIM ensures your cellular data is active from landing, but VPN connectivity itself depends on the regulatory environment.

SIM registration and ID requirements

Strict real-name registration with passport; in-person verification at carrier store required With a prepaid eSIM, the provider handles registration remotely. You do not need to visit a counter or present your passport in person.

Speed and coverage in rural areas

China Mobile provides the broadest coverage in China, but speeds drop outside major cities. Urban areas average 180 Mbps. Rural areas may see 5-15 Mbps on LTE. 5G is available in select areas (widespread).

Common error messages

"eSIM not supported"
Your phone is carrier-locked. Contact your home carrier to unlock (24-72 hours).
"No service"
Data roaming is off on the travel eSIM line. Enable it in Settings.
"Plan expired"
The plan was activated too early (during a layover). Contact the provider for a replacement.
"Unable to activate"
eSIM profile slot is full. Delete unused profiles in Settings > Cellular. iPhones hold 8 profiles (2 active).

Data Tips

Optimizing your data plan in China

How much data you need

[object Object],[object Object],[object Object],[object Object]

Stretching your data in China

  • Download offline maps before departure (saves 50-200 MB/day)
  • Use China's good hotel and cafe WiFi for heavy downloads
  • Turn off background app refresh and auto-play videos
  • Enable Low Data Mode (iPhone) or Data Saver (Android)

Topping up mid-trip

If your plan runs out, buy additional data through the Nomad app. Top-ups apply instantly with no new QR code needed. Alternatively, switch to an unlimited daily plan starting at $3.35/day.

How to top up your eSIM mid-trip

Peak season data congestion

During Apr-May and Sep-Oct in China, network congestion can reduce speeds in popular tourist areas. Spring and autumn offer best weather; avoid Golden Week (Oct 1-7) and Chinese New Year for extreme crowds Consider upgrading one plan tier during peak months for a buffer.

Installation Methods

How to install: QR code scanning vs in-app setup for China

QR Code Scan Method

  1. Purchase your China eSIM from any provider (Airalo, Holafly, Saily, Nomad). The QR code arrives via email or is displayed in your account dashboard.
  2. Display the QR code on a separate screen — laptop, tablet, or a printed copy. You cannot scan a QR code on the same phone you are installing the eSIM on.
  3. On your phone: iPhone — Settings > Cellular > Add eSIM > Use QR Code. Samsung — Settings > Connections > SIM Manager > Add eSIM > Scan QR Code. Pixel — Settings > Network & Internet > SIMs > Add SIM > Download SIM.
  4. Point your camera at the QR code. The eSIM profile downloads in 5-15 seconds over WiFi.
  5. Tap "Activate" or "Add" when prompted. Label the plan "China Data."
  6. Disable the eSIM after installation. Enable it after landing at Beijing Capital (PEK) / Pudong (PVG) / Daxing (PKX).

Pros:

  • Works with any eSIM provider — universal method across all platforms.
  • No app installation required — uses your phone's built-in Settings flow.
  • The QR code is a one-time-use credential: once scanned, the profile is on your device permanently (until you delete it).
  • Faster initial setup: scanning takes 10 seconds vs app download + account creation.

Cons:

  • Requires a second screen to display the QR code — cannot scan from the same device.
  • Requires WiFi or mobile data for the download.
  • If the scan fails, you need the SM-DP+ manual entry code from the confirmation email as a fallback.
  • QR codes are single-use for most providers — losing the email before scanning means contacting support.

Best for: Travelers installing at home before departure, users who prefer not to install additional apps, and anyone setting up a China eSIM on a secondary phone or tablet.

Provider App Installation

  1. Download your provider's app: Airalo (iOS/Android), Holafly (iOS/Android), Saily (iOS/Android), or Nomad (iOS/Android).
  2. Create an account or sign in. Search for "China" in the destination field.
  3. Select and purchase your plan. Plans start at $3.49 for 1GB.
  4. The app presents an "Install" button for your China plan. Tap it. The app opens your phone's native eSIM settings and guides you through the process.
  5. Follow the on-screen prompts. The app handles QR code scanning internally — no second screen needed.
  6. After installation, the app shows your plan status: data remaining, validity period, and connected carrier (China Mobile in China).

Pros:

  • No second screen needed — the app handles the QR scanning or direct provisioning internally.
  • Built-in plan management: monitor data usage, check validity, and view carrier connection status.
  • Easier reactivation: if you visit ${country.name} again, the app stores your purchase history.
  • Some apps (Airalo, Saily) support direct eSIM provisioning — no QR code needed at all.

Cons:

  • Requires downloading a 50-100 MB app before installation — uses storage and initial data.
  • Account creation adds 2-3 minutes to the process.
  • Each provider has a separate app — managing plans across Airalo, Holafly, and Saily means three apps.
  • App updates can temporarily break the installation flow on older OS versions.

Best for: First-time eSIM users who want guided setup, travelers who buy from the same provider regularly, and anyone who wants in-app data monitoring during their China trip.

Recommendation: My recommendation for China: use the provider app if it is your first eSIM. The guided installation catches common mistakes (wrong data line selected, data roaming left off, profile not labeled). For experienced users, the QR code method is 2 minutes faster and does not require an app download. Both methods connect to China Mobile's 5G/LTE network at 180 Mbps average.

Timing

Should you set up your eSIM before or after landing in China?

Pre-Departure Setup (Recommended)

The optimal window: 24 hours before departure. Your home WiFi handles the QR download. You have time to troubleshoot if the scan fails (use manual SM-DP+ entry as fallback). The China profile sits dormant until you enable it at Beijing Capital (PEK) / Pudong (PVG) / Daxing (PKX). China Mobile registers in 60-90 seconds. No surprises, no scrambling, no dependency on airport infrastructure.

Pros:

  • Reliable WiFi at home — no captive portals or unstable airport networks.
  • No time pressure. If the QR code fails, you have hours to contact support.
  • Jet-lag-free setup. Configuring Settings after a 12-hour flight leads to mistakes.
  • Immediate data on landing: China Mobile connects in 60-90 seconds, no WiFi search.
  • No SIM counter detour at Beijing Capital (PEK) / Pudong (PVG) / Daxing (PKX) — skip the 20-40 min; real-name verification process queue and $15-30 for 3-10GB / 7-30 days tourist markup.
  • Plan timer does not start until China Mobile registers the profile — no wasted days.

Cons:

  • Must remember to install before departure — not an option if you forget.
  • Plan validity begins on first network connection, not purchase date — but activating during a layover still burns a day.
  • If you change your travel dates after installation, the eSIM sits unused until you travel.

Choose when: Best for: all planned trips. Install 24-48 hours before departure.

On-Arrival Setup at Beijing Capital (PEK) / Pudong (PVG) / Daxing (PKX)

Arrival installation works in theory but fails in practice for many travelers. The WiFi at Beijing Capital (PEK) / Pudong (PVG) / Daxing (PKX) handles eSIM downloads. Jet lag, language barriers on the WiFi login page, and Settings navigation in a loud terminal all increase error rates. China requires passport registration for physical SIMs — eSIM avoids this, but only if you can complete the download.

Pros:

  • Plan timer starts immediately after first connection — no risk of accidental activation during layovers.
  • No advance planning needed — works for last-minute trips.
  • SIM counter at Beijing Capital (PEK) / Pudong (PVG) / Daxing (PKX) provides a physical backup option ($15-30 for 3-10GB / 7-30 days).

Cons:

  • Requires WiFi for QR scan.
  • Jet-lag mistakes: wrong data line, roaming left off, APN entry errors.
  • 5-15 minutes of setup time at the airport instead of immediate data.
  • SIM counter costs $15-30 for 3-10GB / 7-30 days with a 20-40 min; real-name verification process queue — your only alternative if the eSIM download fails.
  • Physical SIM requires Strict real-name registration with passport — adds 15-30 minutes.

Choose when: Best for: last-minute trips where pre-departure setup was not possible.

Verdict: Home setup wins on every metric: reliability, speed, cost, and stress. The China eSIM installs in 5 minutes at home and connects in 90 seconds at Beijing Capital (PEK) / Pudong (PVG) / Daxing (PKX). On-arrival setup takes 10-20 minutes in a less favorable environment. Install at home.

Post-activation checklist for China

eSIM verification checklist for China
StepWhat to checkIf it fails
Check carrier name in status barYour status bar should display "China Mobile" or "China Unicom" within 60-90 seconds of enabling the eSIM. The 5G/LTE indicator confirms your connection type.If "No Service" or "Searching..." persists after 2 minutes: Settings > Cellular > Network Selection > turn off Automatic, wait 10 seconds, turn it back on. If China Mobile does not appear, restart your phone.
Verify data line assignmentOpen Settings > Cellular > Cellular Data. Confirm the China eSIM is selected as the active data line. If your home SIM is selected, all data routes through your home carrier at roaming rates.Tap "Cellular Data" and select the China eSIM. Disable "Allow Cellular Data Switching" to prevent automatic fallback to your home SIM when China Mobile's signal dips briefly.
Confirm data roaming is enabledSettings > Cellular > [China eSIM] > Data Roaming must be ON. Most travel eSIM plans route through roaming agreements — data roaming must be enabled for the travel line specifically.Toggle Data Roaming ON for the China eSIM line only. Leave roaming OFF on your home SIM to prevent accidental charges.
Load a webpage to verify data flowOpen Safari or Chrome and load any webpage. If the page renders within 3 seconds, your China eSIM is delivering data on China Mobile's 5G/LTE network. Slow loads (10+ seconds) indicate APN misconfiguration.If the page does not load: check Settings > Cellular > Cellular Data Network for APN settings. If blank, contact your eSIM provider for the correct APN string for China Mobile's network in China.
Test messaging appsText messaging in WhatsApp, Telegram, and iMessage works over data. Voice and video calls are restricted in China — enable your VPN before attempting WhatsApp or FaceTime calls.If calls do not connect, enable your VPN first. China blocks VoIP at the network level. If the VPN does not connect, try a different VPN server location.
Verify emergency dialing capabilityEmergency calls to 110/120/119 work from any active SIM in China, even without data. With eSIM data active, your phone's emergency SOS feature also shares your GPS location with responders.Emergency calls bypass SIM restrictions. If your eSIM has no data, the call still connects through any available network. Store 110/120/119 in your phone contacts as "China Emergency."
Check remaining data balanceOpen your eSIM provider's app (Airalo, Holafly, Saily, or Nomad) and verify your remaining data and validity period. The plan timer started when China Mobile first registered your profile.If the app shows zero data remaining immediately after activation, the plan may have been activated during a layover. Contact your provider's support for a replacement or top-up.

Data Tips

Make your China eSIM data last longer

Download offline maps before departure

Google Maps and Maps.me allow offline downloads for specific regions. Download China's major cities before leaving WiFi. Offline maps use zero cellular data for navigation. A single city map is 50-200 MB — download at home, not on your eSIM.

Disable background app refresh

Go to Settings > General > Background App Refresh (iPhone) or Settings > Battery > Background Usage Limits (Samsung). Background refresh consumes 200-500 MB per day without visible activity. Social media apps, news feeds, and email clients refresh constantly. Disable all except essential apps while on your China eSIM.

Pause cloud sync and auto-backups

iCloud Photos, Google Photos, and cloud backup services upload images and videos over cellular data. A single day of vacation photos can consume 1-3 GB in background uploads. Pause cloud sync: iPhone — Settings > Photos > Cellular Data > toggle off. Android — Google Photos > Settings > Back up & sync > Use cellular data > off. Sync manually over WiFi at your hotel each evening.

Use WiFi when available

China has good public WiFi. Free WiFi in most hotels and cafes. Use hotel and cafe WiFi for data-heavy tasks: video calls, software updates, large downloads, and cloud sync. Reserve your eSIM data for on-the-go navigation and messaging.

Set video quality to low on streaming apps

Standard definition video uses about 700 MB per hour. HD uses 1.5-3 GB. If you stream on your China eSIM, set Netflix, YouTube, and other apps to "Data Saver" or "Low" quality. Better approach: download episodes over WiFi before going out.

Monitor data usage in real time

iPhone: Settings > Cellular > scroll to usage stats for each app. Samsung: Settings > Connections > Data Usage > Mobile Data Usage. Check daily. Set a data warning at 80% of your plan limit: iPhone uses Screen Time limits; Samsung has a built-in data warning under Data Usage settings. Your eSIM provider's app also shows remaining data for your China plan.

Plan for 8-day trips

The average trip to China lasts 8 days. At 1.5GB per day for standard use (maps, messaging, email, light browsing), budget 12-16 GB total. A 1GB plan at $3.49 covers this comfortably.

Peak season data note: Apr-May

During Apr-May, China Mobile's network carries heavier traffic in tourist areas. Network congestion increases retransmission overhead, meaning your phone uses 10-20% more data per webpage load. Budget a slightly larger plan during peak months.

Business

Enterprise eSIM deployment for China travel

A prepaid eSIM for China solves the corporate connectivity problem without procurement overhead. China Mobile's 5G/LTE network delivers 180 Mbps average. Each device gets its own plan, installed before departure, active on landing. No SIM card logistics, no carrier registration at Beijing Capital (PEK) / Pudong (PVG) / Daxing (PKX), no IT ticketing system involvement.

Multi-device management

Team deployment checklist for China: (1) Confirm each phone is carrier-unlocked and eSIM-capable. (2) Purchase one plan per device. (3) Distribute QR codes via secure internal channel (not group chat). (4) Each traveler installs and labels their profile before departure. (5) IT verifies MDM compatibility if phones are managed. Per-person cost from $3.49 for 1GB. Total setup time for 5 devices: under 30 minutes.

VPN and security

China blocks VoIP at the carrier level. A corporate VPN is mandatory for video conferencing and voice calls. Pre-departure: install VPN, set eSIM as data line, test video call quality. Post-arrival: enable eSIM at Beijing Capital (PEK) / Pudong (PVG) / Daxing (PKX), activate VPN, verify corporate app access. China Mobile's 5G/LTE network at 180 Mbps average supports VPN-tunneled video calls without buffering.

Expense tracking

Submit the eSIM provider receipt as a travel expense. The confirmation includes: provider, China, plan tier, price in USD, and purchase timestamp. No ambiguity, no usage-based billing, no multi-page carrier invoice to decipher. For recurring China trips, set up the purchase on a corporate card to automate expense categorization.

Emergency protocol

China emergency protocol: dial 110/120/119 for police, fire, or medical. This call connects through any available network. Your eSIM data on China Mobile enables additional capabilities: GPS location sharing, corporate security app access, embassy contact lookup, and real-time translation for language barriers. Pre-load your company's emergency contact card on your lock screen.

Transfer

Phone upgrade during your China trip: eSIM transfer guide

Replacing your phone during a China trip does not mean losing your eSIM data. The profile on China Mobile's network can move to a new device through direct transfer or provider reissue. Have your original provider confirmation email accessible — it contains the SM-DP+ details needed for manual reactivation.

iPhone to iPhone

iPhone to iPhone (iOS 17+): Settings > Cellular > tap the China eSIM > Transfer to Nearby iPhone. Both phones must be within Bluetooth range, signed into the same Apple ID, and running iOS 17 or later. The transfer takes 2-5 minutes. Your China Mobile connection resumes on the new device within 60 seconds. Quick Start during initial setup also offers eSIM transfer as part of the migration flow.

Android transfer

Samsung to Samsung or Pixel to Pixel: most Android manufacturers do not support direct eSIM transfer between devices. You need a new QR code from your eSIM provider. Contact Airalo (in-app chat, 4 min avg), Holafly (WhatsApp +34 644 44 37 97), or Saily (email support) and request a profile reissue for your China plan. The provider deactivates the old profile and issues a new QR code for the new device. Your remaining data and validity transfer to the new profile.

Cross-platform

iPhone to Android or Android to iPhone: cross-platform eSIM transfer requires provider intervention. Contact your provider's support, explain the device change, and request a new QR code. The China plan (remaining data and validity on China Mobile's 5G/LTE network) transfers to the new profile. Install the new QR code on the replacement device, configure the data line, and enable roaming. China Mobile registers in 60-90 seconds.

Warning: Do not delete the eSIM profile from your old device before confirming the transfer or receiving a new QR code. Deletion without a backup code may permanently deactivate the profile. Contact your provider first, complete the transfer process, and only then remove the old profile.

After Your Trip

Post-trip: what to do with your China eSIM

  1. Disable the China eSIM immediately: Settings > Cellular > [China Data] > turn off "Turn On This Line."
  2. Re-enable your home SIM as the primary data line: Settings > Cellular > Cellular Data > select your home SIM.
  3. Turn off data roaming on all lines: Settings > Cellular > each line > Data Roaming > Off.
  4. Check your China data usage in your provider app — note remaining balance for records or potential refund.
  5. Decide whether to keep or delete the China eSIM profile (see guidance below).

Your China eSIM stays on your phone after the trip unless you remove it manually. For repeat travelers: keep it and buy a new plan next time. For one-time visitors: delete it under Settings > Cellular > Remove Cellular Plan. Either way, disable the China eSIM immediately after returning home — leaving it active may trigger unexpected connection attempts on other networks.
