Setting up an eSIM for your next trip shouldn't be stressful. Whether you are a first-time user or a frequent traveler, following a precise sequence ensures you stay connected from the moment you land. This tutorial covers everything from the initial scan to troubleshooting signal issues at your destination.
When Should I Install the eSIM?
We recommend installing your eSIM on the day of departure so you can connect to the network immediately upon arrival.
Important: The activation process requires an internet connection. Please ensure you have a stable Wi-Fi or cellular data connection during the entire setup process.
How to Activate eSIM on iOS Devices
Follow these four steps to get your iPhone ready for international data.
Step 1: Scan the QR Code
Tap the activation button provided by your provider or scan the QR code manually:
- Go to Settings > Cellular > Add Cellular Plan.
- Select Scan QR Code.
- Scan the QR code provided in your eSIM credentials.
Step 2: Complete Installation and Configuration
After a successful scan, your device will automatically download the profile.
- Label the line: Name it "eSIM" or the destination name (e.g., "China eSIM").
- Assign services: Select this line for Cellular Data, Voice, and SMS.
- Set Defaults: Set this eSIM as the Default Cellular Data Line.
Step 3: Set SIM Preferences (Before Departure)
To avoid unexpected roaming charges on your primary home SIM:
- Go to Settings > Cellular > Cellular Data.
- Ensure your Physical SIM (Main) is selected as the active data line until you arrive.
- Disable Automatic Switching: Go to Cellular Data Options > Allow Switching Cellular Data > Turn OFF.
Step 4: Enable Data After Arrival
Once you've reached your destination:
- Confirm international roaming is enabled with your provider if you plan to keep your home line active for SMS.
- Go to Settings > Cellular and switch Cellular Data to your eSIM line.
- Enable Data Roaming: Go to Cellular Data Options > Data Roaming > Turn ON.
QR Code FAQs
Can the same QR code be used on multiple devices?
No. Each eSIM QR code can only be activated once on a single device. It cannot be reused or shared. Please scan it directly on the device you intend to use for travel.
Do I need to enable 'Data Roaming'?
Yes. Most travel eSIMs require Data Roaming to be ON in your device settings to access local partner networks abroad.
Troubleshooting Common Issues
"Cannot Add This Carrier's Cellular Plan"
This usually means your device is carrier-locked.
- Check: Settings > General > About > Carrier Lock.
- It must say "No SIM Restrictions". If it doesn't, contact your original carrier to unlock the device.
"Cannot Complete Cellular Plan Change"
Possible causes:
- eSIM Limit: You may have reached the maximum number of eSIMs allowed on your device. Remove old, unused profiles.
- Disabled Data: Ensure cellular data is turned on during setup.
- Pre-activation: The eSIM might have been activated on another device already.
"This Code is No Longer Valid"
- Confirm the eSIM hasn't been activated before.
- Ensure a strong, stable internet connection (Wi-Fi is best).
- Try Manual Entry using the SM-DP+ address and activation code provided.
Connecting to the Network After Arrival
For iOS Devices
- Open Settings > Cellular.
- Under Cellular Plans, select your eSIM.
- Tap Enable This Line.
- Return to Cellular, select the eSIM again, and ensure Data Roaming is ON.
For Android Devices
- Open Settings > Network & Internet > Mobile Network (or SIMs).
- Select your travel eSIM.
- Turn ON "Use eSIM".
- Ensure Mobile Data and Roaming are both enabled.
Improving Signal and Stability
If your connection is unstable or you can't access the internet:
- Toggle Airplane Mode: Turn it on for 10 seconds, then off to refresh the connection.
- Manual Network Selection: If automatic fails, go to Network settings and manually select a supported local carrier.
- Check Data Balance: Displayed balances might not update in real-time. Ensure you haven't exhausted your quota.
- Restart Your Device: The classic fix—restarting often resolves temporary network handshake issues.
- Change Location: Move to an open area; avoid basements or thick-walled structures.
