On a supported Samsung Galaxy phone, add your travel plan through the eSIM options in SIM manager using the provider's installation details. Start by checking your exact device variant, getting an internet connection and reading the package timing rules. Samsung's menu names vary with software, so match the instructions to your phone rather than looking for an identical screen.
Confirm that these instructions fit your phone
Use your model number and purchase region to consult Samsung's compatibility guidance. This guide applies to Galaxy devices that support eSIM; it does not establish support for every Galaxy phone or another Android brand. Also confirm that the device can use the travel provider rather than being restricted to the original carrier. Samsung's eSIM compatibility guidance
If you are unsure, complete the device compatibility checks before purchasing. A missing menu is a reason to investigate the model and software, not a reason to erase settings or install unofficial firmware.
Prepare the installation details
Keep the provider's QR code or activation information available and connect the phone to reliable internet. Read the order instructions for the installation window and the event that starts validity. A download may be possible before travel, but whether it is appropriate depends on those package conditions.
If you plan to scan the QR with the phone, display it on another screen or use the provider's supported same-device method. Do not copy an activation code from a different order as a test. Keep the QR, activation information and any requested device identifiers private.
Use the eSIM entry in SIM manager
Samsung's UK guide describes opening Settings → Connections → SIM card manager, adding a mobile plan and using the QR option. Other software may call these SIM manager and Add eSIM. Use the equivalent options shown on your supported device.
- Open the SIM management screen.
- Choose the option to add an eSIM or mobile plan.
- Select QR installation and scan the code issued for your order.
- Follow the prompts until the new plan appears.
Samsung also documents manual addition using an activation code supplied by the provider. If you need that method, use the precise details and format supplied for your package. Do not guess a server address or change the code's characters. Samsung's QR and activation-code instructions
Automatic installation is a separate provider-supported method. The presence of an automatic option does not mean your travel package has been pre-assigned to the phone.
Identify the new line before choosing mobile data
After installation, inspect the lines in SIM manager and identify the travel plan. If naming is available, choose a label that distinguishes it from your home line. Keep a note of which line is which so that you can apply the provider's roaming instructions to the right one.
| What you observe | How to interpret it |
|---|---|
| New plan appears | Installation has reached the profile-added stage |
| No service before arriving | Check included destinations and the start conditions before diagnosing a fault |
| Internet works only with Wi-Fi on | You have not yet demonstrated a working cellular-data session |
| Data works after Wi-Fi is off | The selected mobile connection is working at that location and time |
An installed line and an active package are different things. Neither proves that a second country is included or that you will always receive a particular network generation.
Configure the plan using its own instructions
When the travel line should be used, select the appropriate mobile-data line using your model's SIM settings. Check the home carrier's charges before keeping the home line enabled abroad. Do not assume that choosing travel data makes all activity on the home line free.
Follow the package instructions for roaming, APN and network selection; there is no single set of values in this guide for all Galaxy phones and travel plans. At the destination, a small page opened with Wi-Fi temporarily disabled is a useful initial check. Save larger downloads until you have confirmed the package's remaining allowance.
Stop and ask support when a code or installation fails
Record the exact error and whether a new line already appears. Check the order details and your internet connection. A used-code message needs the provider's assessment; repeatedly trying the code on different devices or deleting a profile can make the situation harder to resolve.
Send the model, software version, package reference, error, location and time through the provider's private support channel. Avoid public screenshots containing activation details or identifiers. Follow package-specific support instructions before making changes that remove a line.
For the remaining purchase checks, return to the travel eSIM selection guide.
