How to install an eSIM
Installing an eSIM is usually quick and simple. This guide explains how to prepare your device, add the eSIM profile and connect to mobile data while travelling.
What you need to install an eSIM
- An eSIM-compatible smartphone or tablet
- A stable Wi-Fi or mobile internet connection
- Your eSIM QR code or manual installation details
- Access to the mobile network settings of your device
- The eSIM plan you purchased for your destination
When should I install my eSIM?
It is usually best to install your travel eSIM before departure while you still have a reliable internet connection. However, you should check when the validity period of your plan begins. Some plans start after the first connection to a supported network, while others may begin immediately after installation.
How to install an eSIM using a QR code
- Open the mobile network or cellular settings on your device.
- Choose the option to add an eSIM or mobile plan.
- Select the option to use a QR code.
- Scan the QR code provided with your eSIM order.
- Confirm that you want to download and install the mobile plan.
- Wait until the eSIM profile has been added successfully.
- Choose a clear name for the new eSIM, such as Travel eSIM.
- Keep the eSIM turned off until you are ready to use it, unless your plan requires immediate activation.
How to install an eSIM manually
If you cannot scan the QR code, you may be able to install the eSIM manually. Open the option for entering installation details and type the activation information supplied with your order. Depending on the provider, this may include an SM-DP+ address, an activation code and an optional confirmation code.
How to activate your travel eSIM
- Open the mobile network or cellular settings.
- Select the newly installed travel eSIM.
- Turn on the eSIM line.
- Choose the travel eSIM for mobile data.
- Enable data roaming for the travel eSIM if the plan instructions require it.
- Disable mobile data switching if you do not want your primary SIM to use data.
- Wait for the device to connect to a supported mobile network.
Why might data roaming need to be enabled?
Many travel eSIM plans connect through partner mobile networks in your destination. For this reason, data roaming may need to be enabled on the travel eSIM line. This does not mean that your primary SIM should also use roaming. Always confirm that the travel eSIM is selected for mobile data.
How to install an eSIM on an iPhone
On a compatible iPhone, open Settings, choose Cellular or Mobile Service and select Add eSIM. Follow the on-screen instructions to scan the QR code or enter the details manually. After installation, name the plan and choose which SIM should be used for mobile data.
How to install an eSIM on an Android device
The exact menu names vary between Android manufacturers. Open Settings and look for Connections, Network and Internet, SIM Manager or Mobile Network. Choose Add eSIM, Add mobile plan or Download a SIM, then scan the QR code and complete the on-screen steps.
What to check if the eSIM does not connect
- Make sure the eSIM line is turned on
- Confirm that the travel eSIM is selected for mobile data
- Enable data roaming on the travel eSIM if required
- Turn airplane mode on and off
- Restart the device
- Check that you are in a destination covered by the plan
- Try selecting a supported mobile network manually
- Check the access point settings if your provider supplied them
Should I remove my physical SIM card?
In most cases, you do not need to remove your physical SIM card. A compatible Dual SIM device can often keep the primary SIM active for calls and messages while the travel eSIM provides mobile data.
Can I keep using WhatsApp after installing an eSIM?
Installing a travel eSIM normally does not change the phone number registered in WhatsApp. When the application asks whether you want to change your number, you can usually keep the existing number and use the travel eSIM only for internet access.
What should I do after the trip?
When you no longer need the travel eSIM, you can turn the line off in your device settings. You may remove the profile after the plan has expired, but first confirm that you will not need to reinstall or reuse it.
