Four Ways to Get Data in China — Compared Honestly
Every option below works. They differ on price, hassle, and one detail that matters more than people expect: whether you end up with a Chinese phone number. Here is the comparison we give our own travelers.
| Option | How It Works | Cost | Chinese Number? |
|---|---|---|---|
| Travel eSIM | Buy online, scan a QR code, data activates on landing. Data-only. | Lowest per GB | No |
| Local China SIM | Buy at an airport counter or carrier store with your passport; real-name registration required. | Low | Yes (+86) |
| US carrier roaming | Your existing plan's travel pass — nothing to install. | Highest (typically ~$10–12/day) | No (keeps your US number) |
| Pocket WiFi | Rented hotspot shipped or picked up at the airport; share data across devices and people. | Mid (per day) | No |
Our recommendation for most Americans: a travel eSIM as your main data line, your US SIM kept active for texts, and a VPN installed before you fly. That trio covers maps, payments, messaging and banking codes with no airport queue.
How a Travel eSIM Works in China
An eSIM is a digital SIM profile your phone downloads — no plastic card, no tray ejector, no counter. In China, travel eSIMs connect to the major local networks (China Mobile, China Unicom, China Telecom) through a roaming partner.
That roaming detail has a useful side effect: because the data is routed via the partner — often through Hong Kong or Singapore — the apps you use at home generally keep working, unlike data from a local Chinese SIM, which sits behind the Great Firewall. It is not a guarantee for every app at every moment, which is why we still recommend installing a VPN before you fly as your backup and for laptops.
Coverage follows the local networks, which are strong in cities and along high-speed rail lines, and thinner in remote areas — the same coverage a local SIM would give you.
Set Up Your eSIM — Before You Fly
The unlocked rule is absolute: a phone still locked to a US carrier cannot activate any travel eSIM. If you are paying your phone off monthly, call your carrier and ask — many will unlock it for travel once the balance is settled.
No Chinese Number — What That Actually Means
Travel eSIMs are data-only. No +86 number, no local calls, no SMS. For most tourists this matters less than it sounds:
Works fine with your US number: WeChat and Alipay registration (see our payment guide), maps, translation apps, ride-hailing in most cases, and staying in touch with home.
Sometimes asks for a +86 number: a few local services — certain attraction ticket queues, food-delivery apps, some venue WiFi portals. The workarounds are simple: your hotel front desk, a WiFi portal that accepts email, or your guide. ChinaWithEase travelers just message us on WhatsApp and we handle it.
If you know you need a Chinese number — a long stay, business with local partners — get the local SIM instead and accept the registration step, or run both: local SIM for the number, eSIM for data.
eSIM Questions from American Travelers
For most everyday apps, a travel eSIM's data usually keeps working because it routes through partner networks outside mainland China. But a VPN is still the safer setup for laptops, hotel WiFi, and full access — see our VPN guide. The two solve different problems: the eSIM gets you data, the VPN decides what that data can reach.
Your phone must be eSIM-capable and carrier-unlocked. Most iPhones from the XS onward support eSIM; US-sold iPhone 14 and later are eSIM-only. If you bought your phone on a carrier installment plan, check that it is unlocked before you buy an eSIM — a locked phone cannot activate one.
Most travelers use roughly 1–2 GB per day with maps, translation, photos and messaging — heavy video use pushes that higher. For a 10-day trip, a 10–20 GB plan is a typical, comfortable size. Buy a little more than you think you need; topping up mid-trip is easy on hotel WiFi.
Travel eSIMs are data-only: no calls, no SMS, no phone number. Keep your US line switched on (with data roaming off) so bank verification texts and iMessage still arrive, and use WhatsApp or FaceTime over data for calls.
A local SIM is the only option that gives you a Chinese (+86) number, but it requires in-person passport registration and its data sits behind the Great Firewall, so you would still need a VPN for your usual apps. For most tourists, a travel eSIM is simpler; choose the local SIM only if you specifically need a +86 number.
