How to Install an eSIM on Samsung Galaxy S25 Easily

One of the biggest advantages of eSIM technology is the convenience it brings to travel connectivity.

Instead of carrying multiple SIM cards or replacing your primary SIM while abroad, you can activate a travel data plan digitally in just a few minutes.

With built-in eSIM support on the Samsung Galaxy S25, the entire setup process is faster, cleaner, and much more convenient for travelers.

To help you get started with your iRoamly eSIM, this guide walks you through every step of the setup process, including QR code installation, manual activation, mobile data settings, and common troubleshooting tips. Even if this is your first time using an eSIM, you’ll be able to install and activate it on your Galaxy S25 quickly and confidently.

Preparations Before Setting Up iRomly eSIM

• Connect the Galaxy S25 to stable Wi-Fi before adding the eSIM.

• Confirm the phone is unlocked and eSIM-capable in your region. The Galaxy S25 supports eSIM, but carrier firmware, regional variants, or a network lock can still affect whether Add eSIM appears.

• Keep the iRoamly QR code or manual activation details ready from your iRoamly order email or account page.

• Do not delete an installed iRoamly eSIM casually. Many travel eSIM profiles cannot simply be reinstalled after deletion; turn the line off instead unless iRoamly support tells you to remove it.

• Install 1-2 days before travel only when your iRoamly plan timing allows it. The validity period starts when the eSIM connects to any supported network, but timing can vary by destination and package.

• Check whether your specific iRoamly plan includes voice calls or SMS. Some eSIM plans may not include voice calling support, so this feature might not be available depending on your plan.

Method 1: Install the iRoamly eSIM by Scanning the QR Code

1. Open Settings, then tap Connections. You should see the Galaxy S25 network settings page.

2. Tap SIM manager. You should see your physical SIM, eSIM section, and preferred SIM settings.

3. Tap Add eSIM in the eSIMs section. The Galaxy S25 should open Samsung's eSIM setup options.

4. Tap Scan QR code. The QR scanner for adding an eSIM should open.

5. Point the scanner at the iRoamly QR code from your order email or iRoamly account page. Keep the code inside the frame until the phone recognizes it.

6. Tap Add when the phone shows Add iRoamly travel eSIM?. Keep Wi-Fi connected while the eSIM profile downloads.

7. Tap Done when the screen shows iRoamly travel eSIM added. Restart only if the phone or carrier prompt asks you to restart.

Method 2: Install the iRoamly eSIM by Manual Entry

1. Open Settings, then tap Connections. This starts the manual flow from the Galaxy S25 network settings page.

2. Tap SIM manager. You should see the SIM cards, eSIM section, and preferred SIM choices.

3. Tap Add eSIM under eSIMs. The Galaxy S25 should open the eSIM setup page.

4. Tap Scan QR code. Samsung places the manual entry option on the QR scanner page.

5. Tap Enter activation code at the bottom of the QR scanner page. The phone should open the manual activation screen.

6. Paste the complete iRoamly activation code string into Activation code, then tap Add. Samsung's current manual screen uses one Activation code field; the complete string normally follows the LPA:1$SM-DP+ Address$Activation Code format, with a confirmation code only if iRoamly provides one and tells you to include it.

7. Tap Add when the phone shows Add iRoamly travel eSIM?. Keep the Galaxy S25 connected to Wi-Fi while it downloads the eSIM profile.

8. Tap Done after the phone confirms that iRoamly travel eSIM was added. Restart only if prompted.

How to Confirm the iRoamly eSIM Was Installed

1. Open Settings > Connections > SIM manager and confirm that the iRoamly travel eSIM appears under eSIMs and is turned on. If the switch is off, tap it to enable the eSIM.

Set Up the iRoamly eSIM for Travel Data

1. In Settings > Connections > SIM manager, tap Mobile data, then select iRoamly travel eSIM. Leave calls and messages on your primary SIM unless your iRoamly plan specifically includes those services.

2. Open Settings > Connections > Mobile networks, keep Mobile data on, and turn on Data roaming if the iRoamly plan or destination instructions require roaming.

3. Return to Settings > Connections > SIM manager and keep Data switching and backup calling off unless you intentionally want the phone to fall back to another SIM for data. This helps avoid surprise roaming on your primary SIM.

Troubleshooting

• No Add eSIM: update One UI, confirm the Galaxy S25 is unlocked, check for an EID in phone status, and confirm that your regional model and carrier firmware support eSIM.

• QR code already used or will not scan: use the manual method, confirm Wi-Fi is working, and contact iRoamly support before deleting an installed eSIM. Many eSIM QR codes are single-use.

• Installed but no data: select iRoamly travel eSIM for Mobile data, enable Data roaming when required, restart the phone, and confirm your iRoamly plan covers the destination you are in.

• Activation is pending: keep the eSIM installed and wait until the Galaxy S25 connects to a supported destination network. Some travel eSIMs count validity or complete activation only after network connection.

• Region or carrier limitations: Samsung menu labels and eSIM availability can vary by country, carrier firmware, and network lock status even on the same Galaxy S25 model name.

• Voice or SMS does not work: check the exact iRoamly plan details. A plan listed as Data Only is for mobile data and does not include normal cellular voice calls or SMS.

• Reinstall risk: if you are not ready to use the iRoamly eSIM, disable the line in SIM manager instead of removing it unless iRoamly support confirms deletion is safe.

Conclusion

You’ve now finished setting up the iRoamly eSIM on your Samsung Galaxy S25. With the eSIM installed and activated, your phone is prepared to access mobile data abroad without the hassle of changing physical SIM cards during your trip.

For the best experience, make sure the iRoamly eSIM remains selected as the active mobile data line when you arrive at your destination. With everything properly configured, your Galaxy S25 is now set up for a smoother and more convenient travel connectivity experience.
