What to expect
What is an eSIM for China?
An eSIM for China is a digital SIM that adds a prepaid mobile data plan to your phone without a physical SIM card. It runs on China Unicom and China Telecom's 5G/4G LTE networks, covers all of Mainland China (Hong Kong and Macau are not included — you'll need a separate eSIM for those), and lets you keep your home phone number active on your physical SIM at the same time.
What's Included (and What's Not)
Included:
- Mobile data only, on 5G/4G LTE, across all of Mainland China
- Validity options from 1 to 30 days
- Hotspot/tethering to share your connection with other devices
- Dual-SIM use — your physical SIM and phone number stay active for calls and SMS
- Data packages from 500MB to unlimited (Unlimited plans run at full speed up to 15GB/day, then reduce to 1Mbps for the rest of that day)
Not included:
- Voice calls or SMS on the eSIM number itself — this is a data-only eSIM
- Coverage in Hong Kong or Macau
Good to Know: Internet Access in Mainland China
This eSIM routes data through an international upstream network (Singtel), so apps typically restricted in mainland China — including Google, WhatsApp, Instagram, Facebook, YouTube, TikTok, and AI chat tools — work normally, without a VPN.

Things to Know About China eSIMs
How does a China eSIM work?
It adds a prepaid data plan to your phone digitally. Install it through the Klook app or a QR code before you travel, then activate it once you land — your validity period starts only when the eSIM connects to a network in China. Hotspot sharing is supported, and you can add more data to the same eSIM if you run out.
Is an eSIM better than a physical SIM for a China trip?
It skips the need to find a SIM card store or swap out your existing SIM, so your home number and messages keep coming through on your physical SIM while the eSIM handles data. It also avoids standard international roaming fees from your home carrier.
Can I keep my home phone number active while using a China eSIM?
Yes. The eSIM only replaces your data connection — your physical SIM and phone number stay active for calls and texts, so you don't lose reachability on your usual number while traveling.
Terms & Conditions
Cancellation policy
- Cancel before your eSIM connects for a full refund. If you face issues after activation, low usage qualifies for a full refund, while higher usage may qualify for a partial refund plus 10% extra in KlookCash. All refunds are at Klook’s sole discretion.

This eSIM was a good choice since using an eSIM is highly recommended when traveling to China. There were just a few areas where the signal was weak or unavailable. Overall, it worked well. Activation was easy and hassle-free.

It’s worth buying an eSIM. Just make sure to install and activate it before going to China so you’ll have data right away. Some eSIM QR codes or apps may not load once you’re already in China due to restrictions, so it’s best to set it up before arrival

Just used a 5G eSIM on our trip to China and it worked flawlessly 🙌 One of the biggest highlights was being able to access apps that are usually restricted — Facebook, Messenger, Instagram, and Google Maps all worked smoothly without needing any extra setup. The connection was fast, stable, and reliable whether we were navigating the city, messaging friends, or posting updates. No need to worry about VPNs or complicated configurations — everything just worked right away. If you’re traveling to China and want hassle-free internet with full access to your usual apps, a 5G eSIM is definitely worth it 👍

This eSiM is so convenient to use. Activation is just thru the klook app. Just make sure you are connected to wifi at the airport to activate it or activate before flying to your destination. The internet data speed is good. Didnt have trouble connecting to social media.. No VPN required. Recommended. Will buy again.

This data eSIM card worked very well throughout my visit to Xi An, including day trips made to Luoyang and Mount Hua (Huashan). It's a HK-based data sim and there's no issue with accessing Google, WhatsApp, Telegram, Spotify etc. Connection is occasionally laggy or spotty - perhaps China Mobile would be a better telco provider (i believe this eSIM was tied to China Mobile previously before it switched to China Unicom). There's no phone number attached, so do ask the hotel receptionist to provide their local number in order to use Meituan. Not necessary for Didi and most other things as they can be accessed via WeChat or Alipay's mini apps (WeChat & Alipay can be set up in SG with our local numbers).

Relatively good & steady internet connection throughout our brief 5d4n trip to GZ & Zhuhai. The biggest plus point is its pricing is much affordable than the roaming package provided by the home country service provider.
