The Galaxy A35 5G supports Samsung’s current Galaxy eSIM setup flow through Settings > Connections > SIM manager, where travel eSIMs can be added by scanning a QR code or entering an activation code manually. This guide assumes the phone is unlocked, eSIM-capable, and running a recent One UI version.
For most iRoamly travel eSIM orders, scanning the QR code is the quickest path. Manual setup is useful if you are setting up from the same phone that displays the QR code, if the camera cannot scan cleanly, or if iRoamly provides activation details in your account or email.
Some Galaxy A35 5G regional or carrier variants may hide eSIM options. If you do not see Add eSIM, check for software updates, confirm that your exact model supports eSIM, and make sure the phone is not locked to a carrier that blocks eSIM profiles.
Preparations Before Setting Up iRomly eSIM
Connect the Galaxy A35 5G to stable Wi-Fi.
Keep your iRoamly QR code or manual activation code ready.
Make sure the phone is unlocked and eSIM-capable for your region.
Install the travel eSIM 1-2 days before travel when your plan allows it, but check the plan details first.
iRoamly eSIM validity starts from activation; the exact trigger can vary by plan, so confirm whether your plan activates on installation or when it first connects to a supported destination network.
iRoamly travel eSIM plans may not include voice calls or SMS. Check the specific plan details before relying on calls or texts.
Do not delete the iRoamly eSIM casually after installation. Many eSIMs cannot simply be reinstalled from the same QR code.
Shared Setup Steps
Open Settings, then tap Connections. You should move into the network and SIM settings area.
Tap SIM manager. This is where Samsung shows your physical SIMs and installed eSIM profiles.
Tap Add eSIM. The phone will open Samsung’s eSIM setup options.
Method 1: Install the iRoamly eSIM by Scanning a QR Code
Tap Scan QR code. The Galaxy A35 5G will open the eSIM QR scanner.
Point the camera at the iRoamly travel eSIM QR code. Keep the QR code inside the scanning frame until the phone recognizes it.
Review the detected iRoamly travel eSIM profile, then tap Add or Download. Keep Wi-Fi connected while the profile downloads.
Tap Done after the phone confirms the iRoamly eSIM has been added.
Method 2: Install the iRoamly eSIM by Manual Entry
Open Settings, tap Connections, tap SIM manager, then tap Add eSIM. On the setup page, tap Scan QR code.
On the QR scanner screen, tap Enter activation code. This opens Samsung’s manual eSIM entry screen.
Enter the full iRoamly activation code string in the Activation code field, then tap Connect or Add. On Samsung One UI, this manual path uses one complete activation-code string, commonly in an LPA:1$... format, rather than separate SM-DP+ Address and Activation Code boxes.
Wait while the Galaxy A35 5G downloads the iRoamly eSIM, then tap Done when the completion screen appears.
How to Confirm the iRoamly eSIM Was Installed
Open Settings > Connections > SIM manager, then confirm that iRoamly Travel appears under eSIMs and is switched on.
Set Up the iRoamly eSIM for Travel Data
In SIM manager, tap Mobile data, then select iRoamly Travel when you are ready to use the travel eSIM for data.
Open the iRoamly Travel eSIM details, then turn on Data roaming if your iRoamly plan or destination requires roaming for service. Leave your primary SIM selected for calls or texts only if you still want to use it.
Troubleshooting
No Add eSIM: Update One UI, check that your exact Galaxy A35 5G region supports eSIM, confirm the phone is unlocked, and look for an EID in the phone information screen.
QR code fails: Use Method 2 and enter the activation code manually. Also confirm Wi-Fi is working and that the QR code has not already been used.
eSIM installs but no data works: Select iRoamly Travel for Mobile data, turn on Data roaming, restart the phone, and confirm your destination is covered by the plan.
Activation is pending: Stay on Wi-Fi, wait a few minutes, then restart the Galaxy A35 5G if the profile remains stuck.
Deleted eSIM: Contact iRoamly support before attempting another install. A used eSIM QR code may not reinstall.
Voice or SMS unavailable: Check the plan details. Many travel eSIMs are data-only, and voice/SMS availability varies by plan.
Conclusion
For the Galaxy A35 5G, the QR-code method is usually fastest: Settings > Connections > SIM manager > Add eSIM > Scan QR code. Manual setup is the backup path from the same QR screen through Enter activation code, using the full Samsung activation-code string.
Once iRoamly Travel appears in SIM manager, choose it for Mobile data, enable Data roaming when required, and double-check the plan’s activation timing before your trip.
