Oppo eSIM: how to install and activate it

Setting up an eSIM on an Oppo device is a simple process you can complete directly from your phone settings, without using a physical SIM card. If your phone supports this feature, the Oppo eSIM setup process works the same way with any carrier and only takes a few minutes.

To get started, you’ll follow two main stages. First, add the eSIM to your Oppo phone using the installation details provided by your carrier, either by scanning the QR code or entering the information manually. Then, turn on the eSIM and select it for mobile data. Below, you’ll find the exact steps to complete both stages from start to finish.

What you need to install an eSIM on Oppo devices

Before setting up an eSIM on your Oppo phone, it’s important to check the basic requirements.

• An Oppo phone with eSIM support. Not all models support eSIM, and availability may vary by region.
• An unlocked device. Your phone must be unlocked to use an eSIM from another provider.
• A stable Wi-Fi connection. This is required to download and add the eSIM to your device.
• Updated software. Keeping your phone up to date helps to ensure proper eSIM Oppo setup and performance.

How to install an eSIM on Oppo

Installing an eSIM on an Oppo phone can be done in two universal ways, depending on the information provided by your carrier. Both methods follow the same system path and work across supported Oppo models.

Install an eSIM on Oppo using a QR code

• Go to Settings → Mobile network → Tap on eSIM → Toggle on the eSIM switch  → Tap Add eSIM → Select Next → Scan the QR code provided by your carrier → Tap Download and wait for the installation to complete (keep this screen open until the process finishes) → Confirm that the eSIM has been added to your device.

Install an eSIM on Oppo using manual installation details

• Go to Settings → Select Mobile Network → Tap on eSIM → Toggle on the eSIM switch → Tap Add eSIM.

• Tap on Next → Select Need help? → Choose Enter it manually → Copy and paste the full installation details exactly as provided (this is not a link, so do not add spaces or modify characters) → Tap Continue → Select Download and wait for the installation to finish (keep this screen open) → Confirm that the eSIM appears on your device.

How to activate an eSIM on Oppo

Once the eSIM is installed, activating it only requires selecting it for mobile data. This step can be done directly from your phone settings and does not require an internet connection. Follow these steps to activate an international eSIM, like Holafly:

• Go to Settings → Select Mobile network → Disable your personal SIM/eSIM to avoid charges from your carrier → Tap eSIM and make sure it’s enabled by turning on the switch → Tap the three dots next to the Data eSIM of the new installed eSIM and select Enable to confirm activation → Go back to Mobile network and select the Travel eSIM → Turn on the Enable switch → Toggle Data roaming switch.

Troubleshooting Tips:

If your Oppo phone shows the eSIM as active but mobile data isn’t working, this usually isn’t related to the installation. In most cases, the device is still completing a short connection process with a local network. Restarting the phone after activation often resolves the situation. If the connection doesn’t come through, manually selecting a network can help the device connect to the correct carrier.

Important: Never delete your eSIM to fix a connection error. Removing the eSIM profile can permanently invalidate the plan and, in some cases, prevent reinstallation.

Manually select a network on an Oppo eSIM

• Go to Settings → Select Mobile network → Choose your Travel eSIM → Tap Operator → Turn on Auto-select → Tap Off to confirm → Select one carrier from the list and wait a few seconds for the signal to register → Try browsing → If there’s no connection, repeat the process by selecting the next carrier and testing again until you find the one with the strongest signal.
