Alternative providers

Which provider to choose

• Budget travel: Nomad offers the lowest per-GB rate
• Broadest coverage: Airalo covers 200+ countries on one account
• Unlimited data: Holafly removes the data counter entirely
• Privacy: Saily bundles NordVPN under the same account

Automatic APN configuration

Most eSIM profiles auto-configure APN settings for China Mobile's network. After installation, verify the APN is set correctly:

• iPhone: Settings > Cellular > Cellular Data Options > Cellular Data Network
• Android: Settings > Network & Internet > SIMs > (travel eSIM) > Access Point Names

A correctly configured APN shows the carrier name and data type. If the APN field is blank, your phone will attempt to auto-fill on first connection.

Manual APN entry

If auto-configuration fails (rare, typically older Android devices), enter APN settings manually. Check your provider's confirmation email for the exact values. Common fields:

Provider-specific APN values override China Mobile's carrier defaults. Always use the values from your provider, not generic carrier APNs.

5G and LTE band selection

5G is available in China (widespread coverage). To force a network type:

• iPhone: Settings > Cellular > Cellular Data Options > Voice & Data > 5G Auto / LTE
• Android: Settings > Network > Preferred network type > 5G/LTE/3G Auto

Switch to LTE-only to conserve battery in rural areas without 5G towers. World's largest 5G network with 3.5M+ base stations; covers all major cities and many rural areas

Before boarding

The night before your flight, open Settings, add a new eSIM, and scan the QR code from your order email. Your home WiFi provides the clean connection the download needs. After it installs, switch the China profile to off. Leave it dormant until wheels touch the runway. China Mobile picks up the signal within 60-90 seconds of your phone leaving airplane mode.

During the flight

Keep airplane mode on during the flight. Confirm your China eSIM is set as the designated data line under Settings before you descend. Your home SIM stays active for calls and SMS verification codes. If you have not installed a VPN yet, do it now over in-flight WiFi — China restricts VoIP services (Great Firewall blocks most VPN services), and downloading a VPN app after landing may not work.

After landing

Once the seatbelt sign is off, disable airplane mode and enable the China eSIM. China Mobile registers the profile in 30-45 seconds. You have maps, messaging, and ride-share access before the cabin door opens. The SIM counter from China Mobile and China Unicom is in the arrivals hall — expect a 20-40 min; real-name verification process wait and $15-30 for 3-10GB / 7-30 days for a tourist plan. Walk past it.

Leaving the airport

Your eSIM is working. Open your ride-share app and request a pickup while you wait at baggage claim. By the time your bag arrives, the car is already en route. No WiFi hunting, no SIM counter, no wasted minutes. China's emergency number is 110/120/119 — it works without data, but having your eSIM active means you can also share GPS coordinates with emergency services.

Most eSIM plans for China support personal hotspot out of the box. Enable it under Settings > Personal Hotspot (iPhone) or Settings > Connections > Mobile Hotspot (Samsung). Your laptop, tablet, or travel companion's phone connects through your China eSIM on China Mobile's 5G/LTE network. Hotspot throughput typically reaches 108-144 Mbps typical through hotspot. Video calls over hotspot use 300-500 MB per hour. A 1GB plan supports 6-10 hours of video calling before running low.

Provider restrictions

Not every plan includes hotspot. Holafly's unlimited eSIM plans for China restrict tethering to prevent network abuse. Airalo and Nomad include hotspot on their fixed-data plans. If the Personal Hotspot toggle is missing from Settings, the plan blocks it at the carrier level — no workaround exists without switching to a hotspot-enabled plan.

Data impact

Hotspot data consumption is higher than direct phone use: laptops pull desktop-resolution assets. Budget 150-200 MB/hour for browsing, 300-500 MB/hour for video calls, 1.5-3 GB/hour for streaming. Turn off cloud sync, OS updates, and auto-downloads on connected devices to protect your China data allowance.

China requires Strict real-name registration with passport for physical SIM cards. At Beijing Capital (PEK) / Pudong (PVG) / Daxing (PKX), registration means handing your passport to a carrier agent, waiting for the system to process your data, and hoping the activation completes before your ground transport leaves. An eSIM eliminates the registration requirement entirely. Buy it online, install at home, and connect to China Mobile the moment you land.

During Apr-May, Sep-Oct, China's tourist areas push China Mobile's network capacity. Speeds drop to 72-108 Mbps during peak congestion in popular locations during afternoon and evening hours. Early morning (6-9 AM local) typically delivers full-speed connectivity. Buy your eSIM early — price increases during peak season are rare for eSIMs but common at airport SIM counters.

Public WiFi in China is good. Free WiFi in most hotels and cafes. For eSIM installation, use your home WiFi before departure. The QR code scan downloads a small profile (under 1 MB) from the carrier's server. This transfer needs a clean connection — captive portals and login walls at Beijing Capital (PEK) / Pudong (PVG) / Daxing (PKX) or hotels can interrupt it.

Activating without WiFi

Fallback if WiFi is unavailable: manual SM-DP+ entry. Your confirmation email from the eSIM provider includes a server address and activation code. iPhone: Settings > Cellular > Add eSIM > Enter Details Manually. Samsung: Settings > Connections > SIM Manager > Add eSIM > Enter Activation Code. This method works over any internet connection. Save the email offline before departure so you have the codes even without connectivity.

"eSIM Not Supported" error

Cause: Your phone is carrier-locked or the model does not support eSIM.

Fix: Contact your home carrier to unlock (24-72 hours). Verify your model supports eSIM at our compatibility list.

"Unable to Activate eSIM" error

Cause: eSIM profile slot is full, or the QR code was already redeemed.

Fix:Delete unused eSIM profiles in Settings > Cellular. iPhones hold 8 profiles (2 active). If the QR shows as used, contact your provider for a replacement code.

Connected but no data

Cause: Data roaming is off on the travel eSIM, or data is routing through the home SIM.

Fix:Settings > Cellular > select travel eSIM > Data Roaming ON. Also verify: Settings > Cellular > Cellular Data > select the travel eSIM as your data line. Restart your phone after making changes.

Slow speeds on China Mobile

Expected: 180 Mbps. If speeds are noticeably lower: toggle airplane mode on and off. Move to a different area. Try forcing LTE if 5G is congested. During Apr-May/Sep-Oct speeds may drop in tourist areas.

VPN configuration after setup

Provider-specific installation issues

• Airalo: QR code in email and in-app. Re-download available in the app under "My eSIMs"
• Nomad: QR delivered by email only. Check spam folder. No app required for installation
• Holafly: QR code in app and email. Unlimited plans activate on first connection
• Saily: QR in app. VPN configuration separate from eSIM setup
