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.

How to Get Your China eSIM

  1. Purchase your China eSIM on Klook and select a data plan
  2. Check your device is eSIM-compatible before you travel
  3. Install the eSIM via the Klook app or by scanning the QR code
  4. Keep the eSIM turned off until you land in Mainland China
  5. Turn on data roaming and select the Klook eSIM to connect

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.
