The Vivo X90 Pro can use an iRoamly travel eSIM when you have an eSIM-capable regional model and carrier firmware that exposes the eSIM menu. Most global Vivo X90 Pro units run Funtouch OS based on Android, while China-market software and some carrier variants may show different SIM options or may not offer eSIM setup.
For travelers, an iRoamly eSIM lets you add destination data before or during a trip without swapping the physical SIM in your Vivo X90 Pro. The QR code method is usually fastest because it fills in the activation details automatically.
This guide covers both setup paths: scanning the iRoamly QR code and entering the activation details manually. It also shows how to confirm that the eSIM was installed, choose it for mobile data, and handle common setup problems.
Before You Set Up Your iRoamly eSIM
Connect the Vivo X90 Pro to stable Wi-Fi before starting.
Confirm that your Vivo X90 Pro model supports eSIM in your region. If Add eSIM does not appear, the device firmware, region, or carrier build may not support eSIM.
Keep your iRoamly QR code available on another screen or as a printed copy. For manual setup, keep the SM-DP+ address, activation code, and any confirmation code from your iRoamly order details.
Install the eSIM 1-2 days before travel when possible, but check the plan details first. iRoamly eSIM validity starts from activation, and the exact trigger can vary by plan.
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 specific plan page or order details before relying on calls or texts.
Method 1: Install eSIM by Scanning a QR Code
Open Settings on the Vivo X90 Pro, then tap Mobile network. You should see the mobile network page with SIM and data options.
Tap SIM card & mobile network or SIMs, depending on your Funtouch OS version. The next screen should show your physical SIM and any eSIM options.
Tap Add eSIM. If the phone asks whether to use a QR code, choose the QR-code setup option.
Point the Vivo X90 Pro camera scanner at the iRoamly QR code. Keep the QR code flat and fully inside the scan frame until the phone reads it.
Review the detected eSIM profile, then tap Download or Add. Keep Wi-Fi connected while the Vivo X90 Pro downloads the iRoamly eSIM.
When the setup finishes, tap Done. The iRoamly eSIM should now appear on the SIM management screen as an available mobile plan or eSIM profile.
Method 2: Install eSIM Manually
Open Settings, then tap Mobile network. This is the same starting point used for QR-code installation.
Tap SIM card & mobile network or SIMs to open the SIM management page.
Tap Add eSIM, then choose the option to enter details manually. On some Funtouch OS builds, this appears as Enter details manually, Enter activation code, or a similar link on the QR scanning screen.
Enter the iRoamly SM-DP+ Address and Activation Code exactly as shown in your iRoamly order details. If a Confirmation Code field appears and your order includes one, enter it; otherwise leave it blank.
Tap Next, then review the eSIM profile and tap Download or Add. Keep the phone online until the download completes.
Tap Done when Funtouch OS confirms that the eSIM has been added. The iRoamly profile should appear in the same SIM list as your physical SIM.
How to Confirm Your iRoamly eSIM Is Installed
Go to Settings > Mobile network > SIM card & mobile network or SIMs. Look for the new iRoamly eSIM profile under the SIM or eSIM list.
Tap the iRoamly eSIM profile and confirm that the line is turned on. If the phone shows a label field, rename the profile to iRoamly so it is easy to select later.
Check the status bar after arrival or when connected to a supported network. If the plan includes data in that destination, the eSIM should register on a local partner network after activation.
Configure eSIM for Mobile Data
Open Settings > Mobile network, then tap Mobile data or Data SIM. Select the iRoamly eSIM as the line used for mobile data.
Open the iRoamly eSIM profile and turn on Data roaming if your iRoamly plan or destination instructions require roaming. Travel eSIMs often need roaming enabled to connect through partner networks.
Turn off automatic data switching if your Vivo X90 Pro offers that option and you want to avoid using your primary SIM for travel data. Then open a webpage or map app to test the iRoamly data connection.
Troubleshooting
Add eSIM is missing: confirm that your Vivo X90 Pro is an eSIM-capable regional model. Some China-market or carrier-specific builds may not support eSIM even if the phone name is the same.
QR code will not scan: increase screen brightness on the device showing the QR code, clean the Vivo camera lens, and keep the full code inside the scan frame. Use manual entry if scanning still fails.
QR code was already used: do not delete the eSIM and try again repeatedly. Contact iRoamly support because many eSIM QR codes are single-use after profile download.
Manual entry fails: check every character in the SM-DP+ address and activation code. Avoid extra spaces, and only enter a confirmation code if iRoamly provided one.
eSIM is installed but no data works: set iRoamly as the mobile data line, turn on data roaming when required, check that you are in the plan's covered destination, and restart the phone.
Activation is pending: keep Wi-Fi on and wait a few minutes. If the plan activates only after connecting to a supported destination network, it may not fully register before arrival.
Calls or SMS do not work: your iRoamly plan may be data-only. Check your plan details before testing calling or texting features.
Conclusion
With your iRoamly eSIM successfully installed, your Vivo X90 Pro is ready to provide mobile data whenever your travel plan becomes active in a supported destination. Once connected, you can use the internet for navigation, messaging, travel bookings, translation tools, and other everyday services without spending extra time configuring your phone after arrival.
Preparing your travel connection before departure helps make the beginning of your trip much smoother. With your mobile data already set up, you can get online more quickly and focus on enjoying your journey instead of dealing with network setup at your destination.
