If this is your first time using an eSIM on the Galaxy Z Fold7, the setup process is usually much easier than many people expect. Instead of waiting for a physical SIM card delivery or changing your existing SIM setup, you can install your travel eSIM digitally through the Samsung settings menu in just a few steps.
This gives you a faster and more convenient way to prepare mobile data before your trip while reducing the hassle of managing physical SIM cards.
Many travelers prefer to install their eSIM before departure so they can connect to local networks more quickly after arrival.
In this guide, you’ll learn how to install and activate your iRoamly eSIM on the Galaxy Z Fold7, including QR code installation, manual activation, mobile data setup, and troubleshooting steps to help you complete the process smoothly.
Preparations Before Setting Up iRomly eSIM
Connect the Galaxy Z Fold7 to stable Wi-Fi before downloading the eSIM.
Confirm the phone is unlocked, eSIM-capable, and not restricted by regional or carrier firmware.
Keep your iRoamly QR code and manual activation details nearby. They may appear in your iRoamly account, order page, purchase email, or setup instructions.
Do not delete the iRoamly eSIM after installation unless iRoamly support tells you to. Many eSIM profiles cannot simply be downloaded again after removal.
Install the eSIM 1-2 days before travel when you have reliable Wi-Fi, but check your plan before turning on travel data. iRoamly eSIM validity starts from activation, and the exact activation trigger can vary by plan.
iRoamly travel eSIM plans may be data-only. Voice calls and SMS availability varies by plan, so verify the plan details before relying on them.
Shared Setup Steps for Both Methods
Open Settings, then tap Connections in the left Settings pane. The right pane should show connection settings for Wi-Fi, Bluetooth, SIMs, and mobile networks.
Tap SIM manager in the Connections pane. Samsung should open the page where physical SIMs, eSIMs, and preferred SIM choices are managed.
Tap Add eSIM under eSIMs. The Galaxy Z Fold7 should open the eSIM setup choices.
Method 1: Install the iRoamly eSIM by Scanning a QR Code
Tap Scan QR code on the Add eSIM screen. This opens Samsung's QR scanner for downloading an eSIM profile.
Place the iRoamly QR code inside the scanner frame. Keep the whole code visible until the Galaxy Z Fold7 recognizes it.
Review the detected iRoamly Travel eSIM, then tap Add. Keep Wi-Fi connected while the eSIM profile downloads.
Tap Done when Samsung confirms the eSIM has been added. If your phone asks for a restart, restart before testing the travel line.
Method 2: Install the iRoamly eSIM by Manual Entry
Samsung's manual path for this flow uses one Activation code field. If iRoamly provides a full activation-code string, paste it exactly. If iRoamly provides separate SM-DP+ Address and Activation Code values, enter them as one activation string in the format LPA:1$SM-DP-ADDRESS$ACTIVATION-CODE. Only include a confirmation code if your iRoamly instructions explicitly provide one.
From the same Add eSIM screen, tap Scan QR code. Manual entry is reached from the scanner page on this Samsung setup flow.
Tap Enter activation code on the Scan QR code screen. The Galaxy Z Fold7 should open the manual activation-code page.
Type or paste the iRoamly activation string into Activation code, then tap Next. Keep Wi-Fi connected while Samsung checks the code.
Review the detected iRoamly Travel eSIM, then tap Add. The phone should begin downloading the eSIM profile.
Tap Done when the eSIM added confirmation appears. If Samsung recommends restarting, restart before changing mobile data settings.
How to Confirm the iRoamly eSIM Was Installed
Open Settings > Connections > SIM manager, then confirm iRoamly Travel eSIM appears under eSIMs and is turned on.
Set Up the iRoamly eSIM for Travel Data
In SIM manager, tap Mobile data, then select iRoamly Travel eSIM. Leave Calls and Messages on your primary SIM unless your iRoamly plan specifically includes voice or SMS.
Open the iRoamly Travel eSIM line settings, then turn on Data roaming if your destination plan requires roaming. Travel eSIMs often connect through partner networks, so roaming may be required for data.
Return to SIM manager and check that Mobile data still points to iRoamly Travel eSIM. Keep automatic switching or fallback data features off if you want to avoid unwanted primary-SIM data use.
Troubleshooting
No Add eSIM: Update One UI, confirm the phone is unlocked, check for an EID in device settings, and verify that your regional Galaxy Z Fold7 variant and carrier firmware allow eSIM setup.
QR code already used or will not scan: Use Enter activation code instead. Make sure the QR code is not expired, cropped, dim, already installed, or displayed on the same phone you are trying to scan with.
Manual activation fails: Recheck the full activation string. On this Samsung flow, use the single Activation code field, not separate visible SM-DP+ Address and Activation Code fields.
Installed but no data: Select iRoamly Travel eSIM for Mobile data, enable Data roaming if required, restart the phone, and confirm the iRoamly plan covers your current destination.
Activation pending: Stay on Wi-Fi and wait until the phone reaches a supported destination network. Some travel plans do not begin service until they connect to a supported local network.
Reinstall risk: Do not delete the eSIM just to troubleshoot. Turn the line off instead, because many eSIMs cannot be reinstalled after deletion.
Voice or SMS unavailable: Check the exact iRoamly plan. Many travel eSIM plans are data-only, and voice/SMS should not be assumed.
Validity period concerns: iRoamly plan validity starts from activation. Check your selected plan or order details for the exact activation trigger before installing too early.
Conclusion
Now that you know how to install and activate your iRoamly eSIM on the Galaxy Z Fold7, you can prepare your travel connectivity before leaving home with just a few setup steps. From connecting to Wi-Fi and adding the eSIM to configuring mobile data and roaming settings, the entire process can be completed directly from your device without needing a physical SIM card.
By setting everything up in advance and confirming the correct settings before departure, you can reduce connection delays after arrival and enjoy a smoother mobile data experience throughout your travels.
