How to install eSIM on Oppo phones

To set up and activate your eSIM on an Oppo phone, you just need to follow a few simple steps. Start by checking that your Oppo phone is eSIM-compatible. Then, shop around for an eSIM provider and plan you like, and purchase your eSIM. Your carrier will send you an email with a QR code. From there, just follow these steps:

1. Open your Settings app from the home screen or app menu.
2. Select SIM Card, then tap Mobile/Cellular Data to access network options.
3. Toggle the eSIM option to enable it, then scroll down to accept the T&Cs.
4. Use your device’s camera to scan the QR code provided by your carrier. This code links your device to the mobile service. 
5. The eSIM installation will begin automatically, and within a few moments, your device will connect to the network using eSIM.
6. Once the eSIM is successfully activated, you’ll be able to see it in your network options, ready for calls and data.

This setup ensures that you can seamlessly connect without the need for a physical SIM card. However, with your Oppo device, you can use either your nano SIM or your eSIM – you can toggle between these in your settings, but remember to set your preferred primary line.

How to install eSIM on other Oppo devices

Setting up your eSIM on an Oppo smartwatch is just as simple, and takes just a few moments. Here’s what to do:

1. Open the Wear OS app on your Oppo smartwatch.
2. In the Wear OS app, navigate to Advanced Settings.
3. Go to Mobile/Cellular Data.
4. Follow the on-screen instructions to configure the eSIM.
5. When prompted, confirm by selecting Accept.
6. Scan the QR code on your smartphone, linking your smartwatch to the eSIM service.
7. Allow a few moments for the eSIM to install and activate. Once connected, your smartwatch will be ready to connect independently.

Make sure to keep both your phone and smartwatch connected to the internet during setup for a smooth installation process.

Can you use your eSIM and SIM together on an Oppo phone?

Most eSIM-compatible Oppo models allow you to use both an eSIM and a regular nano-SIM at the same time. This setup is ideal for users who want to maintain separate phone numbers for personal and business use, or for those who travel frequently and need access to multiple networks.

Several newer Oppo models support dual SIM functionality with both an eSIM and a physical SIM:

1. Oppo Find X5 Pro: offers flexibility with dual SIM support and advances 5G capabilities.
2. Oppo Reno 5 series: provides dual SIM capabilities in some regions.
3. Oppo Watch 4 Pro and SE: offer dual eSIM functionality for users needing independent connectivity on their watch.

Once both SIMs are activated, you can easily switch between networks and manage settings for each line within the settings menu. This makes it easy to use data on one network while handling calls and messages on the other.

Can I use eSIM from any provider with your Oppo phone?

Yes, in most cases, you can use an eSIM from various providers on an Oppo phone, as long as your device is unlocked and eSIM-compatible. Carrier support can vary by region, so it’s important to check with your carrier to ensure compatibility–especially if you’re traveling!

If your Oppo phone is carrier-locked, it might restrict eSIM activation to specific carriers. These devices are usually only compatible with eSIMs from the issuing carrier, so if you’re considering switching to an eSIM, make sure you check your phone’s lock status.
