Setting Up eSIM: Internet connection is required for eSIM installation. Please confirm whether your purchased eSIM can be installed before departure or needs to be installed after arriving at your destination. Installing it in a non-destination country/region may cause the eSIM to become invalid or start counting usage duration prematurely.
Enable Data Roaming: Please ensure the data roaming option for your eSIM is enabled.
eSIM installation inquiry:
To confirm if the eSIM is successfully installed, check your phone settings to see if the eSIM appears under "Mobile Services" or "SIM Card Manager." If the eSIM is listed, even if marked as "No Number" (data-only plans), it indicates successful installation. Each QR code can only be used once for installation. If the eSIM has been removed from your device, we cannot provide further assistance.

[Installing eSIM]
1. Open the QR code attachment in your Trip.com app booking and print it in advance or save it to another electronic device. (For iOS 17+ and some Android phones, you can save the QR code image directly to your phone.)

3. With your phone connected to the Internet, tap "Add Cellular Plan" (iOS) or "Add SIM Card" (Android), then scan the QR code to install.
4. If scanning fails, manually enter the "SM-DP+ Address" and "Activation Code" from your booking voucher to install.
5. If steps 3 or 4 fail, your phone may be carrier-locked by your country/region of residence (preventing the use of other carrier frequency bands). Contact your carrier to unlock it before using eSIM.

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.

Can I still purchase your service if I have already activated an eSIM on my phone?
Yes, your phone can store multiple eSIM profiles at the same time. You can choose which one to use in your phone settings.
