Best eSIM for China in 2026: unlimited data, real prices and what to check
Key facts
- A travel eSIM routes your data outside China, so Google, WhatsApp and Instagram work without a VPN — a local Chinese SIM does not.
- VoaSim connects to China Mobile and China Unicom with truly unlimited data: no cap, no throttling, no fair-use clause.
- Flat pricing for China: USD 18.90 for 5 days, USD 30.90 for 10 days, USD 61.90 for 30 days, down to USD 1.78/day on the 60-day plan.
- Days start counting at the first connection in China, so you can buy and install weeks before departure.
- Choose a local SIM instead if you need a Chinese phone number or are staying longer than 90 days.
See the exact price for your dates
China is the one destination where "which eSIM is best" is not just about price. A local SIM bought in Shanghai gives you a Chinese IP address, and that means no Google, no WhatsApp, no Instagram and no Gmail unless you set up a VPN in advance. A travel eSIM behaves differently: it connects to the same local towers but your data exits the country, so your apps just work.
This page explains what to check before you buy, shows VoaSim's exact prices for China, and says plainly when another option — a per-GB plan or a local SIM — is the smarter pick for your trip.
What makes an eSIM "best" for China specifically
Four things decide it, in this order:
- Routing. With a travel eSIM your traffic leaves China before reaching the open internet, so Google Maps, WhatsApp, Instagram and Gmail open normally. A Chinese local SIM does not do this.
- Network access. VoaSim connects automatically to China Mobile and China Unicom, the two networks with the widest reach in Beijing, Shanghai, Xi'an and Guangzhou.
- Data volume. China trips are map-heavy and translation-heavy. Ride-hailing, live translation and photo backups eat gigabytes fast. VoaSim is truly unlimited: no cap, no throttling, no hidden fair-use clause.
- Keeping your number. Your physical SIM stays in the phone, so WhatsApp and banking SMS still land on your usual number. Just turn off your home carrier's data roaming.

Unlimited vs per-GB: which one fits your China trip
Brands like Airalo, Nomad, Ubigi, Saily and GigSky sell China data by the gigabyte through their apps. That model is fine — and sometimes cheaper — if you are a light user. It is the wrong model if you are navigating a megacity all day.
| Your trip | Better pick |
|---|---|
| Hotel Wi-Fi most of the day, a few messages outside | A small per-GB package |
| Maps, DiDi, live translation, video calls home, photo uploads | Unlimited (VoaSim) |
| Two weeks across Beijing, Xi'an and Shanghai | Unlimited, 15 days — USD 42.90 |
| Six months studying or working in China | A local plan with a Chinese ID/passport registration |
With per-GB brands, check three things in their terms before buying: the cap, the validity window, and whether the plan routes outside China. See our comparison hub for how the models differ.

Install before you fly — and when the days start counting
Buy at home, not at Pudong or Daxing arrivals. The QR code lands in your inbox within minutes (plus a WhatsApp heads-up if you left a number), and installation needs a working internet connection — which is exactly what you will not have when you land.
- Buy and receive the QR code by email.
- Install the eSIM profile at home, following the iPhone or Android guide in the email.
- Leave the eSIM line switched off. On Android, do not turn on the eSIM's mobile data before the trip.
- On landing in China, switch the eSIM line on and turn off data roaming on your home carrier's line.
Validity starts at the eSIM's first connection to a network at the destination, not at purchase. So a 10-day plan bought three weeks early still gives you 10 full days in China. Step-by-step help lives in our setup guides.
Compatibility and the honest limits
Check your phone first: dial *#06#. If an EID number appears, your phone supports eSIM. In practice that means iPhone XR or newer, Samsung Galaxy S20 or newer, Google Pixel 3 or newer, and most phones released from 2020 on. Carrier-locked phones must be unlocked first. VoaSim does not sell physical SIM cards.
What this product is not: it is data only. There is no Chinese phone number and no traditional voice calls, so you cannot receive an SMS code from a Chinese service. WhatsApp, FaceTime and app calls work over data on your existing number. Hotspot sharing depends on the plan — ask support before you count on it. On a Yangtze or coastal cruise it works in port, not out at sea.
If anything looks wrong on arrival, the free eSIM Rescue tool diagnoses any brand's eSIM, and our team answers by chat or at hola@voasim.com.
When a local Chinese SIM is the better choice
We would rather you buy the right thing. Go local if:
- You are staying for months. Beyond 90 days a travel eSIM runs out; a local contract with China Mobile or China Unicom is built for that.
- You need a Chinese number. Some apps and services ask for a local mobile number to register. A data-only eSIM cannot provide one.
- You barely use data. If Wi-Fi covers almost everything, a small per-GB package may cost less.
Expect the trade-offs: a shop visit, passport registration, queue time at the airport, and a Chinese IP address that keeps Google and WhatsApp blocked unless you installed a VPN before arriving. Many travelers carry both — a local SIM for the number and a travel eSIM for open, unlimited internet. Compare against carrier options on our roaming page.
