Introduction
An eSIM (embedded SIM) is a digital SIM card built into your device that lets you activate a mobile data plan without inserting a physical card. For travelers heading to China, it means you can buy and activate a plan before you land, skip roaming charges from your home carrier, and stay connected from the moment you arrive.
Why use an eSIM for China
Traveling to China with your home carrier’s roaming enabled is one of the fastest ways to rack up a massive phone bill. Major US carriers charge anywhere from $10 to $25 per day for international roaming in China, and the coverage quality is not always worth it. Picking up a local SIM at the airport sounds like a fix, but it requires a wait in line and a physical swap every time you cross borders.
An eSIM sidesteps all of that. You download a profile before you leave, activate it when you land, and you are online immediately. No queues, no plastic cards, no carrier lock-in. For anyone doing a multi-destination trip and wondering whether to choose an eSIM data plan instead of roaming, China is actually one of the strongest arguments for going the eSIM route.
Ubigi, backed by Transatel (a subsidiary of NTT), offers eSIM coverage in over 200 destinations including mainland China, all managed from a single app on your phone or laptop.
China eSIM plans compared: all options with pricing
Here is a full breakdown of Ubigi data plans for China (data from July 2026), with a “Best for” column to help you pick the right fit:
| Data | Duration | Price | Best for |
|---|---|---|---|
| 1GB | 7 days | $4 | Backup connection or very light use |
| 3GB | 30 days | $8 | Occasional browsing on a long stay |
| 10GB | 7 days | $14 | Short business trip or city travel |
| 10GB | 30 days | $17 | Moderate users on a month-long trip |
| 20GB/month | 30 days | $19 | Best value for extended stays |
| 25GB | 30 days | $35 | Heavy users who want a data buffer |
| Unlimited | 7 days | $26 | Intensive short stay or transit |
| Unlimited | 15 days | $49 | Two-week trips with no data stress |
| Unlimited | 30 days | $78 | Digital nomads or long-term visitors |
The 25GB/month plan at $35 is the standout value option for most travelers. It covers a full 30 days and gives you enough headroom for navigation, messaging, video calls, and light streaming without watching the GB counter. If you are on a quick 5–7 day visit and want zero restrictions, the unlimited 7-day plan at $26 is hard to beat.
For longer assignments or stays, the 20GB/month at $19 is worth exploring if you return to China regularly, as it is a monthly subscription. It can dramatically reduce the cost per day compared to buying several short plans.
How to activate a Ubigi eSIM step by step
Activation is straightforward, but a couple of details matter more for China than for other destinations.
Check device compatibility first
Your phone must support eSIM and be unlocked from your carrier. Most flagship Android devices (Samsung Galaxy S20+, Google Pixel 4+, and newer) and iPhones from XS onward are compatible. Some carrier-locked devices sold in the US require a call to your operator to enable eSIM for international providers. You can also dial the free shortcut *#06#: if you see an EID number, it means your device is compatible.
Install before you board
Download the Ubigi app (iOS or Android), create an account, and purchase your China data plan while you still have a reliable Wi-Fi connection. Once you land in China, accessing the app stores or completing account setup can be slow due to network filtering. Having everything ready before departure eliminates this friction entirely.
Steps to activate
1. If you bought your plan with the app, install your eSIM directly from the dashboard. If you bought it via the website, you receive a QR code by email. Go to Settings > Cellular > Add eSIM, scan the code, and the plan installs automatically.
2. Once you arrive in China, go to your phone’s settings and set the Ubigi eSIM as your data line.
3. Keep your primary SIM active for calls and SMS, your eSIM data plan does not conflict with your voice line.
4. Toggle on data roaming for the eSIM profile (required for international eSIM data to flow through).
The whole process takes under five minutes once the profile is downloaded.
Network coverage and speed in China
Ubigi’s China plans operate through partner networks in mainland China, providing 4G/5G service in urban centers, major highways, and popular tourist destinations. Coverage is strong in cities like Beijing, Shanghai, Guangzhou, Shenzhen, Chengdu, and Xi’an, as well as in most airports and high-speed rail lines.
In very rural areas or mountainous regions (Tibetan plateau, remote western provinces), coverage can thin out, which is consistent with what you would experience on any local SIM as well. For the majority of business and leisure travel itineraries, coverage is reliable enough for Maps, WeChat, messaging, and video calls.
What you need to know about China’s internet restrictions
This is the one thing every traveler needs to understand before landing: China’s Great Firewall applies to all data connections inside the country, including eSIM data. Many international travel eSIMs, including Ubigi, route mobile data through networks outside mainland China. So you could access services such as Google, Gmail, WhatsApp, Instagram, and YouTube without needing a VPN. It’s always worth checking the latest guidance before you travel.
What an eSIM gives you is affordable, reliable access to the Chinese internet and to any services that function within China (WeChat, Baidu Maps, Didi, local booking apps). To access blocked services, you will need a VPN. The catch: many VPN apps are also restricted in China, so you need to install and test your VPN before entering the country.
Tips for staying connected in China
Use WeChat for everything. Even if you have a VPN, WeChat is the dominant communication platform and works natively without one. Most local restaurants, venues, and contacts will use it.
Download offline maps before landing. Google Maps is accessible in limited ways but is unreliable in mainland China, but Apple Maps works in China. Download a region map in the mapping app of your choice before you arrive.
Carry a portable battery. With navigation and translation apps running constantly, battery drain accelerates. A power bank becomes a travel essential.
Buy your eSIM plan early. Do not wait until you are at the airport: airport Wi-Fi quality is inconsistent, and you want the profile installed cleanly on a stable home connection. Once you have your credentials, you don’t need an internet connection to purchase a new data plan.
Consider a monthly data plan for flexibility. If your schedule might extend or you want a buffer, the 30-day plans give you room to travel without rationing data daily.
FAQ
What is the best eSIM for China for a short trip?
For trips of 7 days or less, the Ubigi 10GB/7-day plan at $14 offers the best balance of data and cost for most travelers. If you stream video or use data heavily, the Ubigi Unlimited/7-day plan at $26 removes any worry about running out. Both activate as soon as you arrive and work immediately on landing.
Can I use an eSIM in China without restrictions?
An eSIM gives you mobile data access in China, but it does not bypass the Great Firewall. Services like Google, Instagram, and WhatsApp remain blocked regardless of your data connection type. You will need a VPN installed and tested before entering China to access those platforms. For apps that work natively in China (WeChat, Alipay, local maps) an eSIM works without any extra steps.
Are there unlimited data eSIM plans for China?
Yes. Ubigi offers three unlimited options: Unlimited/7 days at $26, Unlimited/15 days at $49, and Unlimited/30 days at $78. These are ideal for travelers who do not want to monitor usage, attend video meetings regularly, or plan to use navigation and streaming throughout their stay.
How do I activate a Ubigi eSIM?
Download the Ubigi app, purchase your chosen China plan, and install the eSIM profile via the dashboard. Alternatively, if you buy from the website, you will receive a QR code to scan directly in the app. Do this before boarding, ideally at home on a stable Wi-Fi connection. In your phone settings, assign the eSIM as your data line and enable data roaming for that profile. The process takes about five minutes and your connection is ready the moment you land.
Which China eSIM plan offers the best value for a month-long stay?
The Ubigi 25GB/month plan at $35 is the strongest value for a 30-day trip. At under $1.20 per day, it covers maps, messaging, email, and moderate browsing comfortably. Heavy users or those working remotely should consider the Unlimited/30-day plan at $78 for full peace of mind. For international students or extended stays, the 20GB/month plan at $19 is the best choice as it is a monthly subscription.
