Buying and activation
- Choose a Ubigi China plan and check that your phone is carrier-unlocked and eSIM-compatible.
- Scan the QR code sent by email and install the reusable Ubigi eSIM before you travel, while you have a reliable connection.
- Smartstart activates eligible one-off plans when you first connect in a covered destination. Ubigi says a plan that is not activated within six months of purchase expires.
- In China, select Ubigi as your mobile-data line. You can check your balance and buy more data through the Ubigi app, even without Wi-Fi or remaining plan data.
Ubigi advertises hotspot sharing on compatible devices. Your purchased data allowance is shared across connected devices. Its plans are data-only, so you do not receive a Chinese +86 phone number.
Refunds: Eligibility depends on the plan’s usage and the purchase terms. Contact Ubigi support with your order details if a plan does not work as expected.

- Want a choice between fixed data and Unlimited — 10 GB / 30 days is $17.00, while 7-day Unlimited is $24.00.

Yes. Ubigi's reusable eSIM can be topped up through the app, including when you have no remaining data or Wi-Fi connection. Select a compatible data plan for your destination.
Does Ubigi eSIM give me a Chinese phone number?

Can I get a refund on a Ubigi eSIM?
Refund eligibility depends on whether a plan has been activated or used and on the purchase terms. Contact Ubigi support with the order details if there is a problem.
