Actual steps may vary depending on your OS version and device model.
[Installing eSIM]
* Each QR code can only be used on one device. After installation, the eSIM will be linked to that device and cannot be transferred.
Method ① Direct installation via Trip.com app (Android not currently supported):
• iOS users: Open Trip.com app - Go to "Account" - All bookings - Tap "Install".
• Open Trip.com app - Go to "Account" - All bookings - Tap "Install".
Method ② Install via QR code scan or manual input:
1. Open the QR code attachment in your Trip.com booking and print it or save it to another device.
2. Open "Cellular" (iOS) or "SIM manager" (Android) in Settings.
3. With internet connection, tap "Add eSIM" to scan the QR code.
4. If scanning fails (e.g., when using only one device), manually enter the "SM-DP+ Address" and "Activation Code" from your booking confirmation voucher.
5. If steps 3-4 fail, your device might be carrier-locked (restricting other network bands) in your country/region of residence - contact your carrier to unlock before using eSIM.
[Using eSIM]
1. Disable primary SIM and enable eSIM
2. Open "Cellular" (iOS) or "SIM" (Android)
3. If still no connection after these settings, configure APN and restart (see below)
[About APN]
1. Setup steps:
iOS: Settings - Cellular - Select eSIM - Cellular data network
Android: Settings - Connections - Mobile networks - Select eSIM - Access point names (APN) - Create new or edit existing APN

Important note
■ Can only be installed once
Each QR code can only be installed once. If the eSIM has been deleted from the device, we cannot assist you.
■ Internet coverage
The actual signal strength, Internet speed, and 4G/5G service display may vary depending on your location, local carrier network coverage, device compatibility, as well as environmental factors such as terrain, building obstructions, and weather conditions.
■ Disable domestic SIM card roaming
Before using the eSIM, be sure to disable the "data roaming" function on your domestic SIM card to avoid incurring high international roaming charges from using your domestic SIM's mobile network. You will be responsible for all related fees, including roaming charges, overseas SIM/eSIM purchase costs, and transportation expenses. No additional compensation will be provided.
■ Comply with fair data usage principles
To ensure Internet quality and comply with the fair usage policy (FUP), carriers may monitor users who excessively consume data within a short period, which may result in connection interruption or reduced speeds.
To maintain a stable connection, it is recommended to avoid high data consumption activities such as streaming/downloading long videos, software updates, or Internet sharing (hotspot).
FAQ
How do I find out if my phone supports eSIMs?

1. Dial *#06# in the phone call interface. If an EID is displayed, it indicates that your phone supports eSIM. Without an EID, an eSIM cannot be used.
2. Confirm with your carrier to ensure your phone is not locked to a network.

Can I use an eSIM and a SIM card at the same time?
Yes, with dual SIM functionality, you can activate both a physical SIM card and an eSIM simultaneously.
How to solve eSIM hotspot issues? What can I do if my eSIM's hotspot is not working?

2. Ensure any VPNs are disabled
3. Make sure to turn on data roaming
4. Check if the eSIM is set as the primary device

Contact customer service with your booking number and a screenshot of your phone settings so we can provide you with support and assistance.
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.
