[Install eSIM]
Before installation, please make sure:
1. Your device supports eSIM and is not carrier-locked.
2. Your phone is connected to a stable mobile network or Wi-Fi.

After the first installation, the eSIM will be bound to the current device and cannot be installed on or transferred to another device. Please confirm your device before installation.

Method 1: One-Tap Installation
Tap the “Install” button in the Trip.com app or use the “One-Tap Install” link in your order voucher to complete installation.(iOS 17.4 or later is required for iOS devices.)

Method 2: Scan QR Code / Manual Installation (Universal)
1. Open the QR code attachment in your Trip.com order and print it out or save it on another device in advance. (For iOS 17 or above and some Android devices, the QR code image can be saved directly to the phone.)
2. Go to “Settings” → “Cellular/Mobile Data” (iOS) or “SIM Card Manager” (Android).
3. With your phone connected to the internet, tap “Add eSIM/Add Cellular Plan” (iOS) or “Add SIM” (Android), then scan the QR code to install.
4. If scanning is not possible, you can manually enter the “SM-DP+ Address” and “Activation Code” provided in your order.
5. If Steps 3 or 4 fail, your device may be carrier-locked (restricted to a specific network). Please contact your carrier to unlock it before installing the eSIM.

[Activate eSIM]
Please complete the following settings after arriving at your destination:
1. Turn off your primary SIM (or disable mobile data on the primary SIM) and enable the eSIM.
2. Activate the eSIM:
iOS: Go to “Cellular/Mobile Data” and select and enable the eSIM.
Android: Go to “SIM Card Manager/SIM Cards”, enable the eSIM, and set it as the mobile data SIM.
3. Turn on “Data Roaming”.
4. If you still cannot access the internet after the above steps, please configure the APN and restart your phone. See details below.

[About APN]

iOS: “Settings” → “Cellular” → “Cellular Data Network”
Android: “Settings” → “Mobile Network/Cellular Network” → “Access Point Names (APN)”
3. Enter APN: cmhk
4. Restart your phone.

[Using the Renewal Data Plan]
The renewal plan will be activated automatically once your current plan expires. Please do NOT scan the QR code again.
1. For plans with “high-speed data followed by reduced speed”: reduced-speed data will continue to be used until the original plan expires. Restart your phone to start using the renewal plan. (If you need to end it earlier, please contact customer support.)
2. For plans with “high-speed data only (no data after usage)”: after the high-speed data is used up, restart your phone to start using the renewal plan.
If you want to use the eSIM on another device, please select “Book Again” instead of “Request Renewal”. Renewal plans cannot be transferred to another device.
