Preparing your mobile data before a trip can save time and help you stay connected immediately after arrival. With eSIM support on your Galaxy Note 20 Ultra or Note 20 Ultra 5G, you can install and activate a travel plan digitally without removing your current SIM card or visiting a local carrier store.
This gives you more flexibility during travel because you can continue using your regular number while adding a separate line for international data.
eSIM technology is also useful for frequent travelers since multiple profiles can be managed directly from Samsung settings without carrying extra SIM cards.
This guide will show you exactly how to install and activate your eSIM on the Galaxy Note 20 Ultra or Note 20 Ultra 5G using either a QR code or manual setup details.
Preparations Before Setting Up iRomly eSIM
Connect the Galaxy Note20 Ultra or Galaxy Note20 Ultra 5G to stable Wi-Fi before adding the eSIM.
Confirm that your exact model, region, and carrier firmware support eSIM. Some regional or carrier variants may hide Add eSIM.
Check that the phone shows an EID in device information. If there is no EID, that device variant may not support eSIM activation.
Keep the iRoamly QR code or manual activation details ready from your iRoamly order email, success page, app, or account page.
Do not delete an installed iRoamly eSIM casually. Many travel eSIM profiles are single-use and cannot simply be installed again after removal unless iRoamly support reissues them.
Install 1-2 days before travel only when your selected iRoamly plan timing allows it. iRoamly eSIM validity starts from activation; for many current travel eSIM plans, activation begins when the eSIM connects to a supported network. Check the exact destination plan before installing early.
Check whether your specific iRoamly plan includes voice calls or SMS. Many travel eSIM plans are data-only, and voice/SMS availability varies by plan.
Shared Setup Steps for Both Methods
Open Settings, then tap Connections. You should see Samsung's network and connectivity settings.
Tap SIM manager. If your Note20 Ultra build uses older wording, tap SIM card manager instead. You should see the physical SIM and eSIM controls.
Tap Add eSIM under eSIMs. If your carrier build says + Add mobile plan, tap that instead. Samsung opens the eSIM setup choices.
Method 1: Install the iRoamly eSIM by Scanning the QR Code
Tap Scan QR code on the Add eSIM screen. The Galaxy Note20 Ultra opens the eSIM QR scanner.
Point the scanner at the iRoamly QR code from your order email, iRoamly account, or another device. Keep the whole code inside the frame until Samsung recognizes the eSIM profile.
Tap Add when Samsung shows the iRoamly travel eSIM confirmation. Keep Wi-Fi connected while the profile downloads.
Tap Done when Samsung confirms that iRoamly travel eSIM was added. Restart the phone only if the screen or carrier prompt asks you to restart.
Method 2: Install the iRoamly eSIM by Manual Entry
Tap Scan QR code on the Add eSIM screen. Samsung places the manual entry link on the QR scanner page, so this tap is still part of the manual setup path.
Tap Enter activation code at the bottom of the Scan QR code page. Samsung opens the manual activation screen.
Enter the complete iRoamly activation string in the single Activation code field, then tap Add. Samsung's current manual screen uses one complete activation-code field, not separate SM-DP+ Address, Activation Code, and Confirmation Code fields. If iRoamly gives you an Android string beginning with LPA:1$, paste the entire string exactly as provided.
Tap Add when Samsung shows the iRoamly travel eSIM confirmation. Keep the Note20 Ultra on Wi-Fi while it downloads the profile.
Tap Done after Samsung confirms that iRoamly travel eSIM was added. Restart only if prompted.
How to Confirm the iRoamly eSIM Was Installed
Open Settings > Connections > SIM manager, then confirm that iRoamly travel eSIM appears under eSIMs with its switch turned on. If the switch is off, tap it to enable the eSIM when you are ready to use the plan.
Tap Mobile data in SIM manager, then select iRoamly travel eSIM. Leave calls and messages on your primary SIM unless your iRoamly plan specifically includes voice or SMS.
Set Up the iRoamly eSIM for Travel Data
Open Settings > Connections > SIM manager, then make sure the iRoamly travel eSIM switch is on when you want to use travel data. Leave it off before departure if your plan instructions say activation should wait until arrival.
Open Settings > Connections > Mobile networks, then turn on Data roaming if your iRoamly destination or plan instructions require roaming. Travel eSIMs commonly need roaming enabled to connect to partner networks.
Return to Settings > Connections > SIM manager, then open Data switching and backup calling or Data switching. Keep data switching off unless you intentionally want another SIM to take over mobile data. This helps prevent accidental roaming charges on your primary SIM.
Troubleshooting
No Add eSIM or + Add mobile plan: update One UI, confirm the phone is unlocked, check that an EID appears in device information, and confirm that your regional or carrier model supports eSIM.
QR code will not scan: increase brightness on the screen showing the QR code, keep the full code inside the scanner frame, make sure Wi-Fi works, or use Method 2.
QR code says it was already used: check whether the iRoamly eSIM is already installed in SIM manager. Do not delete it and try again without iRoamly support, because many eSIM activation codes are single-use.
Installed but no data: select iRoamly travel eSIM for Mobile data, turn on Data roaming if required, confirm your destination is included in the plan, restart the phone, and wait a few minutes for network registration.
Activation is pending: keep Wi-Fi connected and leave the eSIM installed. If the plan activates only after connecting to a supported destination network, wait until arrival before expecting full service.
Voice or SMS does not work: check the exact iRoamly plan. A data-only plan will not provide standard cellular calls or SMS, even if mobile data is working.
Region or carrier limitation: Note20 Ultra menu labels and eSIM availability can vary by country, carrier firmware, and lock status. If the phone is locked to a carrier, it may reject a travel eSIM.
Reinstall risk: if you are not ready to use the iRoamly eSIM, turn the line off in SIM manager instead of removing it unless iRoamly support confirms deletion is safe.
Conclusion
After setup is finished, your Galaxy Note 20 Ultra or Note 20 Ultra 5G will be ready to use your travel eSIM whenever you enable it for mobile data abroad. Because the eSIM profile is stored digitally on your device, switching between plans or destinations becomes more convenient and flexible during travel.
Features like dual SIM support also allow you to keep your regular number active while using a separate line for international data. Before your trip begins, it’s a good idea to confirm that the correct eSIM is enabled and that roaming settings are configured properly so your connection works smoothly once you arrive.
