The Samsung Galaxy A36 is a practical travel phone for using an iRoamly travel eSIM, especially if you want to keep your physical SIM active while adding a separate mobile data plan for your destination. On current Samsung One UI, the eSIM setup path is handled through Settings > Connections > SIM manager > Add eSIM.
This guide covers both ways to install your iRoamly travel eSIM: scanning the QR code and entering the activation code manually. The QR method is usually fastest, while manual entry is useful if you are reading the QR code on the same phone, the camera cannot scan it clearly, or the QR code has to be copied from your iRoamly order details.
The Galaxy A36 menu labels can vary slightly by region, carrier firmware, and software version. If your phone does not show Add eSIM, check the troubleshooting section before deleting or resetting anything.
Preparations Before Setting Up iRomly eSIM
Connect your Galaxy A36 to stable Wi-Fi.
Make sure the phone is unlocked and supports eSIM in your region/carrier variant.
Keep your iRoamly QR code or manual activation details open on another device, printed page, or your iRoamly account.
Do not delete an installed eSIM casually. Many travel eSIMs cannot simply be reinstalled after removal.
Install the eSIM 1-2 days before travel when appropriate, but check your specific iRoamly plan first.
iRoamly eSIM validity starts from activation. Check your plan details for the exact activation trigger.
iRoamly travel eSIM plans may not include voice calls or SMS. Voice/SMS availability varies by plan.
Shared Setup Steps
Open Settings, then tap Connections. You should see the network and SIM options for the phone.

On the Connections screen, tap SIM manager. This opens the page where Samsung lists physical SIMs, eSIMs, and preferred SIM choices.

In SIM manager, tap Add eSIM. The phone will open Samsung’s eSIM setup options.

Method 1: Install the iRoamly eSIM by Scanning a QR Code
On the Add eSIM screen, tap Scan QR code. Your Galaxy A36 will open the QR scanner for adding an eSIM.

Point the scanner at the iRoamly QR code. Keep the QR code inside the frame until the phone recognizes the eSIM profile.

When the iRoamly travel eSIM confirmation appears, tap Add. The phone will begin downloading the eSIM profile.

Wait while the Galaxy A36 adds the iRoamly eSIM. Keep Wi-Fi connected and do not close Settings during the download.

When the success screen appears, tap Done. If your phone asks you to restart, restart before testing mobile data.

Method 2: Install the iRoamly eSIM by Manual Entry
Open Settings, tap Connections, tap SIM manager, then tap Add eSIM. This is the same Samsung setup path used for QR installation.

On the Add eSIM or QR setup screen, tap Enter activation code. This opens Samsung’s manual eSIM entry page.

Paste the full activation code string from iRoamly into the Activation code field. On this Samsung One UI flow, manual entry uses one complete activation code string, commonly in an LPA:1$...$... format, rather than separate SM-DP+ Address and Activation Code boxes.

Tap Add. The Galaxy A36 will verify the code and begin downloading the iRoamly eSIM profile.

Wait for the eSIM to finish adding, then tap Done on the success screen. If prompted, restart the phone.

How to Confirm the iRoamly eSIM Was Installed
Open Settings > Connections > SIM manager. Confirm that iRoamly Travel eSIM appears under eSIMs and that its switch is turned on.

Set Up the iRoamly eSIM for Travel Data
In SIM manager, tap Mobile data, then choose iRoamly Travel eSIM. This makes the iRoamly line the phone’s data connection for travel.

Open the iRoamly eSIM’s mobile network settings and turn on Data roaming if your iRoamly plan or destination requires it. Travel eSIMs usually need roaming enabled to connect outside the home network profile.

Troubleshooting
If Add eSIM is missing, update your Galaxy A36 software, check that your model/region supports eSIM, confirm the phone is unlocked, and look for an EID in the phone’s status information.
If the QR code will not scan, increase screen brightness on the device showing the QR code, clean the camera lens, or use Enter activation code.
If the QR code was already used, do not delete the eSIM and try again. Contact iRoamly support because many eSIM QR codes are single-use.
If the eSIM installs but has no data, select iRoamly Travel eSIM for Mobile data, turn on Data roaming, restart the phone, and confirm your plan covers the destination.
If activation stays pending, keep Wi-Fi on, wait a few minutes, restart the phone, and check whether the plan activates only after connecting to a supported destination network.
If calls or SMS do not work, check the exact iRoamly plan details. Many travel eSIM plans are data-only.
If you no longer need the plan, turn the eSIM off instead of deleting it unless iRoamly support tells you removal is safe.
Conclusion
For the Galaxy A36 on current Samsung One UI, the QR code method is the simplest way to install an iRoamly travel eSIM: Settings > Connections > SIM manager > Add eSIM > Scan QR code. Manual setup is the backup path, using Samsung’s Enter activation code screen with the full activation code string from iRoamly.
After installation, always confirm that iRoamly Travel eSIM appears in SIM manager, switch it on, select it for Mobile data, and enable Data roaming when your destination plan requires it. Before you travel, double-check when your specific iRoamly plan validity starts and whether the plan includes data only or also supports voice/SMS.
