The Google Pixel 4a is an eSIM-capable Pixel model, which makes it a practical travel phone when you want mobile data without swapping your physical SIM. For an iRoamly travel eSIM, you normally install the plan while connected to Wi-Fi, then turn it on for data after you reach your destination.
This guide uses the current Pixel Android menu labels for eSIM setup: Network & internet, SIMs, Add SIM, and Set up an eSIM. Some carrier builds or older Android versions may show slightly different wording, but the flow should stay close on an unlocked Pixel 4a with eSIM support.
You will find two complete setup methods below. Use the QR code method if you can display the iRoamly QR code on another screen or print it. Use manual entry if the QR code cannot be scanned or if iRoamly gives you the activation details separately.
Preparations Before Setting Up iRoamly eSIM
Connect your Pixel 4a to a stable Wi-Fi network before installing the eSIM.
Confirm the Pixel 4a is unlocked and that your region/carrier variant supports eSIM.
Keep your iRoamly QR code or manual activation details ready. iRoamly provides the QR code and activation code by email, on the order success page, or in your iRoamly account.
Do not delete the iRoamly eSIM after installation unless iRoamly support tells you to. Many travel eSIMs cannot be reinstalled after removal.
Install the eSIM 1-2 days before travel if possible, but leave the iRoamly line off until you need it.
iRoamly plan validity starts from activation. For many iRoamly plans, validity starts when the eSIM connects to a supported network, so check the exact policy shown on your plan page.
Many iRoamly travel eSIM plans are data only. Voice calls and SMS availability varies by plan, so check the plan details before relying on them.
Method 1: Install the iRoamly eSIM by Scanning a QR Code
Open Settings, then tap Network & internet. You should see Pixel connectivity settings such as Internet, Calls & SMS, and SIMs.
Tap SIMs. The Pixel 4a should open the page where your active SIM and SIM preferences are managed.
Tap Add SIM. The phone should open the SIM setup flow.
Tap Set up an eSIM. Keep the phone connected to Wi-Fi while the setup screen prepares the eSIM download.
When the QR scanner appears, point the Pixel 4a camera at the iRoamly QR code. The QR code should be on another phone, tablet, computer, or printed page; do not scan a code already displayed on the same Pixel screen.
Review the detected mobile plan, then tap Download or Activate if prompted. Wait on Wi-Fi while the Pixel downloads the iRoamly eSIM profile.
Tap Done when the setup completes. The iRoamly eSIM should now appear in Settings > Network & internet > SIMs.
Method 2: Install the iRoamly eSIM by Manual Entry
Open Settings, then tap Network & internet. This is the same Pixel entry point used for QR code setup.
Tap SIMs to open SIM management.
Tap Add SIM to start adding another SIM profile.
Tap Set up an eSIM. Wait for the QR setup page to open.
On the QR screen, tap Need help? or the manual-entry option shown on your Pixel, then choose Enter it manually. The manual activation screen should open.
Enter the activation code from iRoamly, then tap Continue. On Pixel Android, manual setup commonly uses one full activation-code field. If iRoamly shows separate SM-DP+ Address and Activation Code values, combine them only in the exact format provided by iRoamly, such as a full LPA:1$... activation string, or follow the on-screen field labels if your Android version shows separate fields.
Review the iRoamly mobile plan, then tap Download or Activate. Keep Wi-Fi connected until the download finishes.
Tap Done when setup completes. The iRoamly eSIM should be saved on the Pixel 4a.
How to Confirm the iRoamly eSIM Was Installed
Open Settings > Network & internet > SIMs, then look for the new iRoamly eSIM or a newly added downloaded SIM profile. It may appear with a generic carrier name until it connects to the destination network.
Tap the iRoamly eSIM profile and confirm that Use SIM is available or turned on. If you are still at home before your trip, you can leave it off until arrival to avoid early network connection.
Set Up the iRoamly eSIM for Travel Data
In Settings > Network & internet > SIMs, tap Mobile data, then select the iRoamly eSIM when you are ready to use travel data. This makes the iRoamly line the Pixel 4a data SIM.
Open the iRoamly eSIM profile and turn on Roaming if your destination plan requires it. Keep your primary SIM available for calls or texts only if you want to avoid accidental data use on your home plan.
Turn off Switch data SIM automatically if you do not want the Pixel 4a to move mobile data back to your primary SIM. This helps prevent roaming charges on your home line.
Troubleshooting
If Add SIM or Set up an eSIM is missing, confirm your Pixel 4a is not locked to a carrier and that your carrier/region supports eSIM on this device.
If the QR code says it was already used, do not delete the eSIM or keep retrying. Open your iRoamly account or contact iRoamly support for a replacement or next steps.
If the eSIM installs but there is no data, confirm the iRoamly eSIM is selected for Mobile data, turn on Roaming if required, and restart the phone.
If activation stays pending, wait until you are in the covered destination and connected to a supported network. Many travel eSIM plans activate only after they connect to a supported network.
If the manual activation code fails, check that there are no spaces or missing characters. Use the exact activation format shown by iRoamly and the exact field labels shown on your Pixel.
If your Pixel 4a uses an older Android version, menu names may differ. Look for equivalent labels such as Mobile network, Download SIM, or Add carrier.
Conclusion
Once your iRoamly eSIM is successfully installed on the Pixel 4a, most of the setup work is already behind you. The eSIM profile will remain stored on the device, so when your trip begins, you can simply enable the iRoamly line and use it for mobile data without going through the installation process again. This can be especially helpful when you arrive in a new country and need immediate access to maps, messaging apps, ride-hailing services, or travel information.
Before you travel, it's a good idea to double-check your plan's activation policy, coverage area, and roaming requirements. As long as the iRoamly eSIM is installed and ready to use, getting connected abroad should be a quick adjustment rather than a last-minute task. With your travel data already prepared, you can spend less time managing network settings and more time enjoying your trip.
