The Vivo V29 Lite 5G is a regional case: eSIM support is available only on compatible European variants. If your phone was bought outside Europe, or your carrier firmware hides eSIM options, the Add eSIM button may not appear even though the model name looks the same.
For supported Vivo V29 Lite 5G devices, the setup flow is handled through Funtouch OS on Android, usually from Settings > Network & internet > SIMs or Mobile network. This guide uses those labels and notes where software versions may show slightly different wording.
You can install your iRoamly travel eSIM by scanning the QR code from your iRoamly order, or by entering the activation details manually. The QR method is faster, while manual entry is useful if you are reading the QR code on the same phone or the camera cannot scan it clearly.
Before You Set Up Your iRoamly eSIM
Confirm that your Vivo V29 Lite 5G is a European eSIM-supported variant. If Add eSIM is missing, your region, carrier firmware, or model variant may not support eSIM.
Connect to stable Wi-Fi before installing the eSIM profile.
Keep your iRoamly QR code available on another screen or printed page.
Keep the manual activation details ready, including the SM-DP+ Address, Activation Code, and any optional confirmation code if iRoamly provides one.
Make sure the phone is unlocked for the network you plan to use while traveling.
Install the iRoamly eSIM 1-2 days before travel when possible, but check your plan terms first. iRoamly eSIM validity starts from activation, and the activation trigger can vary by plan or destination.
Do not delete the iRoamly eSIM after installation unless iRoamly support tells you to. Many travel eSIM profiles cannot be reinstalled after removal.
iRoamly plans may be data-only. Voice calls and SMS availability varies by plan, so check the details before relying on calls or text messages.
Method 1: Install eSIM by Scanning a QR Code
Open Settings on your Vivo V29 Lite 5G and tap Network & internet.
Tap SIMs or Mobile network, depending on your Funtouch OS version. You should see your current physical SIM and mobile network options.
Tap Add eSIM. If the phone asks whether to use a physical SIM or eSIM, choose the eSIM option.
Tap Scan QR code and point the camera at the iRoamly QR code from your order email or iRoamly account page. Keep the QR code flat, bright, and fully inside the scanner.
When the iRoamly eSIM plan is detected, tap Download or Continue. Keep the phone connected to Wi-Fi while Funtouch OS downloads the eSIM profile.
Tap Done after the phone confirms that the eSIM was added. Leave the new iRoamly eSIM turned on unless you are waiting to activate it closer to travel.
Method 2: Install eSIM Manually
Open Settings on your Vivo V29 Lite 5G and tap Network & internet.
Tap SIMs or Mobile network to open the SIM management page.
Tap Add eSIM to start adding a new mobile plan.
Tap Need help? or Enter details manually on the QR-code screen. The exact wording may vary slightly by Funtouch OS build, but the manual option is on the QR setup page.
Enter the iRoamly SM-DP+ Address and Activation Code exactly as shown in your iRoamly order. If a Confirmation Code field appears and iRoamly did not provide one, leave it blank.
Tap Continue, then tap Download when the phone finds the iRoamly eSIM profile. Stay on Wi-Fi until the download finishes.
Tap Done when Funtouch OS confirms that the eSIM has been added.
How to Confirm Your iRoamly eSIM Is Installed
Go to Settings > Network & internet > SIMs or Mobile network, then look for the new iRoamly eSIM under your SIM list. It may appear as iRoamly, Travel, or a carrier profile name.
Tap the iRoamly eSIM profile and confirm that Use SIM or the line toggle is switched on. If you are not traveling yet, you can leave mobile data off until you arrive.
Configure eSIM for Mobile Data
Open Settings > Network & internet > SIMs or Mobile network, then tap Mobile data or Preferred SIM for mobile data.
Select the iRoamly eSIM as the mobile data SIM. This keeps travel data on iRoamly instead of your primary SIM.
Open the iRoamly eSIM details and switch on Roaming or Data roaming if your iRoamly destination instructions require it. Then test a webpage with Wi-Fi turned off.
Troubleshooting
Add eSIM is missing: confirm the phone is a European eSIM-supported Vivo V29 Lite 5G variant. Non-European variants may only support physical nano-SIM cards.
The QR code will not scan: raise screen brightness on the device showing the QR code, clean the camera lens, and make sure the whole code is visible. If it still fails, use manual entry.
The activation details do not work: copy the SM-DP+ Address and Activation Code exactly. Avoid spaces before or after the values.
The QR code says it was already used: most eSIM QR codes can be installed only once. Do not delete the eSIM and try again; contact iRoamly support.
The eSIM is installed but has no data: select the iRoamly eSIM for mobile data, enable data roaming if required, turn Wi-Fi off, and restart the phone.
Activation stays pending: wait until you are in the destination network coverage area if the plan activates on first connection. Keep the eSIM installed and avoid repeated deletion attempts.
Calls or SMS do not work: check the iRoamly plan details. Many travel eSIMs are for mobile data only.
Conclusion
For a supported European Vivo V29 Lite 5G, scanning the iRoamly QR code through Network & internet > SIMs or Mobile network > Add eSIM is the quickest setup path. Manual entry reaches the same result when you type the SM-DP+ Address and Activation Code from your iRoamly order, so it is the better fallback when the QR code is on the same phone.
After installation, the important checks are simple: confirm the iRoamly profile appears in the SIM list, switch on Use SIM, choose iRoamly for mobile data, and enable data roaming when your destination instructions require it. Once those settings are in place, your Vivo V29 Lite 5G is ready to use iRoamly travel data without relying on your primary SIM for roaming.
