How to use
[Install eSIM]
Before installing, please ensure you are connected to a stable mobile data or Wi-Fi network.
For devices running iOS 17.4 or later, you can quickly install the eSIM directly within the Trip.com app by tapping the "Install" button (Note: Since one QR code can only be installed on one phone, please confirm that the device you intend to use the eSIM on is the current device before proceeding. If it is not the current device, do not tap the button, otherwise the QR code will become unusable afterwards.).
The specific steps are as follows:
Trip.com app ➡ Account ➡ All Orders ➡ Tap the eSIM order you wish to use to enter the order details page, then tap the "Install" button.
For other versions and models, the general installation methods are as follows:
Scan QR Code / Enter eSIM Information Manually:
1. Open the QR code attachment from the order in the Trip.com app, and print it in advance or save it to another electronic device. (iOS 17 and above systems can directly save it to the phone)
2. Open Cellular Network (iOS) or SIM Card Management (Android) in Settings.
3. While the phone is connected to the internet, click "Add Cellular Network" (iOS) or "Add SIM Card Management" (Android) and scan the QR code to install.
4. If you can't scan the code, enter the "SM-DP+Address and Activation Code" from the order receipt to install.
5. If steps 3/4 fail, your phone may be locked by the home carrier (unable to use other carrier networks). Contact the carrier to unlock it before using eSIM.

Your renewal data plan will automatically activate after the validity period of your initial plan ends. Please DO NOT scan the QR code again to install it.

After the initial plan's validity period ends, restart your phone to begin using your renewal plan. (If you need to end the initial plan early, please contact customer support.)
2. For plans with high-speed data that stops after usage: Once your high-speed data runs out, restart your phone to start using your renewal plan.

Where can I find the EID and IMEI on my phone?
The EID functions as a digital signature that links devices to mobile networks, typically comprising 32 characters, which include both letters and numbers. The IMEI, or International Mobile Equipment Identity, serves as a unique identifier for your phone and is generally 15 digits long.
For iPhones, you can find your EID and IMEI by going to "Settings" > "General" > "About" > EID/IMEI. Another quick way to find your EID and IMEI is by dialing *#06#, which will display a screen with your device information.
For Samsung phones, go to "Settings" > "About Phone" > "Status Information" > IMEI/EID

How do I activate a renewal?
For total volume-based eSIMs, the renewal will automatically activate after the first plan has been completely used up. You don't need to scan the code again for installation. Once the first plan is used up, refresh the network, wait a few minutes, and it will automatically renew for you.
For daily-based eSIMs: The renewal booking will automatically activate after the days covered by the first booking's package have used up. You don't need to scan the code again.
Additionally, if you want to use eSIM on a different phone, please do not place a renewal booking, as renewal bookings do not support changing phones.
