Quick answer
Send six cropped screenshots: the SIM list with line labels, the selected mobile-data line, travel-line data roaming, APN details without activation secrets, signal and network name, and the order's remaining-data/validity screen where available. Add the exact phone model, city, time, purchase channel, order number and error text. Never show the full QR code, activation code, password, OTP or full card number.
A screenshot is useful only when it proves a setting. A full screen filled with personal notifications may expose data without showing the selected SIM. Crop carefully but keep the setting name visible, label the travel line clearly and explain what action failed after Wi-Fi was switched off.
Screenshot 1–2: SIM list and data selection
The SIM list shows whether the profile exists and whether old lines may be confused with it. The mobile-data screen shows which line actually carries internet traffic. Rename the travel line “China Data” before capturing.
Mask phone numbers and unrelated line details, but keep the labels and on/off state visible.
Screenshot 3–4: roaming and APN
Open the China Data line and capture its data-roaming switch. Then capture the APN field required by the order, excluding any activation code or secret. These screens address two common causes of signal-without-data.
Do not copy an APN from another provider or old eSIM.
Screenshot 5: signal and network
Capture the status showing signal type and, where the settings allow it, the registered network name. Add the city, indoor/outdoor location and local time in the text message because a screenshot alone does not show coverage conditions.
Do not treat a 4G label as automatic failure when data works.
Screenshot 6: order status
Show the product name, remaining data, validity and expiry where the channel provides them. Mask payment information and other orders. State whether the order came from the website or Taobao.
This helps separate configuration from an expired, not-yet-valid or depleted plan.
What the six screenshots diagnose
| Situation | What it means | Best next step |
|---|---|---|
| SIM list + mobile-data line | Profile presence and line selection | Confirm China Data is active and selected |
| Roaming + APN | Travel-line configuration | Compare only with the exact order |
| Signal + order status | Coverage, registration, validity and allowance | Add city, time and exact error |
A reliable pre-purchase check
Before purchasing, save the exact model and country of purchase; after purchasing, save the channel and order number.
- 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
Do not post troubleshooting screenshots publicly until all phone numbers, email addresses, notifications, QR codes, activation secrets and payment details have been removed.
Test the eSIM without wasting data
State whether a new ordinary webpage loads with Wi-Fi off; this single fact helps separate mobile-data failure from one-app failure.
- 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
Should I send the QR code to prove the order?
No. Send the order number, not the full QR code or activation secret.
Is a speed-test screenshot required?
No. Settings and a real webpage result are usually more useful and safer for fixed data.
Can I send screenshots in English support email?
Yes. Add the phone, location, order and exact error in text as well.

Choose a China travel eSIM
If the China eSIM does not connect, send six safe screenshots with one complete English support message. Coverage, capacity, validity, routing, hotspot, 5G and activation rules are governed by the selected product and order. Real-world speed varies by phone bands, location, indoor signal and network load.
