Quick answer
After payment, save the order number and confirm the selected destination, capacity and validity. Receive the QR code or manual installation details, then read what starts the validity period. Add the eSIM under trusted internet only when permitted, label it clearly, and at the destination select it for mobile data, follow its roaming/APN instructions and test with Wi-Fi off.
The word “activation” is used differently across eSIM products. For one plan it may mean installation; for another it may mean the first network registration in the covered destination. A trustworthy process separates the stages and uses the exact order wording instead of assumptions from a previous eSIM.
Stage 1: preserve the order
Save the product name, destination, capacity, validity, order number and purchase channel. Confirm that the transaction is complete and the checkout email is correct. These details are more useful for support than an uncropped bank screenshot.
If anything is wrong, pause before installing and ask the original purchase channel to check.
Stage 2: receive and protect installation details
The delivery may include a QR code, a link or manual SM-DP+ information. Treat those details as private. Do not forward the full code to a public computer, forum or social-media comment.
Read whether the code is single-use and whether installation starts the validity period.
Stage 3: add and label the eSIM
Under trusted Wi-Fi or a personal hotspot, use the phone's Add eSIM menu. Label the new line “China Data” so it cannot be confused with the home SIM. If the line appears in the SIM list, do not scan the code again.
It may show no service before the traveler enters the covered destination.
Stage 4: connect after arrival
Select China Data for mobile data, disable home-line data roaming, follow the order's travel-line roaming and APN instructions, then switch Wi-Fi off. Open a new webpage before testing maps and essential apps.
Keep the home line only if its roaming, voice and SMS costs are understood.
Four stages and their evidence
| Situation | What it means | Best next step |
|---|---|---|
| Order complete | Order number and selected product exist | Save the confirmation |
| Installation delivered | QR code or manual details are available | Read validity and single-use rules |
| eSIM added | A new line appears in SIM settings | Label it and avoid rescanning |
| Data connected | New webpages load with Wi-Fi off | Test essential apps next |
A reliable pre-purchase check
Confirm compatibility and validity before payment so the digital delivery can be used on the intended phone and date.
- Phone: confirm that Add eSIM appears in settings, the device is carrier-unlocked, and the exact model plus country of purchase are known.
- Coverage: choose mainland China coverage for a China-only trip; compare the China/Hong Kong/Macau product when mobile data is also needed in Hong Kong or Macau.
- Plan: compare 5GB, 10GB and 20GB options by maps, video, cloud backup and hotspot use. Capacity and validity are governed by the selected product and order.
- Features: check routing, hotspot, 5G, APN and data-roaming instructions for the exact product instead of applying rules from another eSIM.
- Security: keep the order number and installation instructions private. Never post the full QR code, activation code, password or one-time verification code.
Important limitation
Receiving a QR code does not automatically prove that the plan is already active, but it also does not mean the code can be stored forever. The exact order controls both installation and validity.
Test the eSIM without wasting data
The first connection test should be small and practical, not a long 4K video or repeated speed test.
- Connect to trusted internet and add the eSIM without deleting the home SIM.
- Follow the order's validity rule before switching the travel line on.
- At the destination, select the travel eSIM for mobile data and follow its data-roaming and APN instructions.
- Turn Wi-Fi off and open a new ordinary webpage, then search for a new location in a map app.
- Only after that should you test the payment, ride-hailing, messaging or work apps you actually need.
If the connection fails, save the city, time, signal, selected data line, roaming setting, APN and exact error message. Do not delete the eSIM, reset the entire phone or scan the QR code repeatedly as a first response.
Frequently asked questions
Can I install before flying?
Only if the order says installation does not start validity too early. Follow the exact rule.
Why is there no service before China?
A mainland-China-only plan may not register outside its coverage area.
Can I keep my home SIM active?
Usually on a compatible dual-SIM phone, but check the home carrier's roaming and SMS charges.
