The OnePlus 7 series, released in 2019, remains a popular choice for many smartphone users. But if you're wondering about OnePlus 7 eSIM compatibility or how to activate eSIM on your OnePlus 7 Pro, 7T, or 7T Pro, you've come to the right place.

Whether you're looking to use dual SIM functionality or simply want to understand your options, we'll cover all the essential details.

What is eSIM?

An eSIM (embedded SIM) is a digital SIM card that's built directly into your smartphone's hardware. Unlike traditional physical SIM cards, eSIMs don't require you to insert a removable chip into your device. Instead, you can download and activate carrier profiles digitally, making it incredibly convenient for travelers, business users, or anyone who needs multiple phone numbers.

The eSIM technology offers several compelling benefits, which includes - but not limited to - the following:

• Instant activation: No need to wait for physical SIM cards to arrive
• Multiple profiles: Store several carrier profiles simultaneously
• Travel convenience: Easily switch between local carriers when abroad
• Space saving: Allows manufacturers to design slimmer devices
• Enhanced security: Harder to remove or tamper with compared to physical SIMs
• Environmental benefits: Reduces plastic waste from SIM card production

The OnePlus 7 series includes four main variants, each with distinct specifications but unfortunately limited eSIM support: 

Important Note: None of the OnePlus 7 series devices have native eSIM compatibility. OnePlus only introduced native eSIM support starting with the OnePlus 11 in 2023. However, there are workarounds to getting eSIM functionality on OnePlus 7 models - #Keep_Reading.

How to Verify if a OnePlus Device Supports eSIM

If you're unsure about your device's eSIM capabilities, here are three reliable methods to check:

1. Settings Path: Navigate to Settings → Network & Internet → SIM & Network and look for an "Add eSIM" option
2. Dial Code Method: Enter *#06# on your phone's dialer. If you see an EID (Embedded SIM ID), your device has eSIM hardware support
3. Manufacturer Confirmation: Contact OnePlus support or your network carrier for definitive confirmation about your specific model and region

What You Need Before Activating eSIM

Before attempting to activate eSIM functionality on your OnePlus 7 series device, ensure you have the following requirements:

Essential Requirements

Unlocked Device: Your OnePlus 7 must be carrier-unlocked. Locked devices may not support third-party eSIM solutions or carrier switching.

Active Internet Connection: A stable Wi-Fi or cellular connection is crucial for downloading eSIM profiles and completing activation.

Updated Operating System: Ensure your OnePlus 7 is running the latest available OxygenOS version for optimal compatibility with third-party eSIM solutions.

eSIM QR Code or Activation Details: Obtain these from your chosen eSIM provider. This typically includes a QR code to scan or manual activation codes.

Third-Party eSIM Card: Since OnePlus 7 models lack native support, you'll need a physical adapter card from services like eSIM.me.

Additional Considerations

• Backup Current Settings: Create a backup of your current network settings before making changes
• Carrier Compatibility: Verify that your intended eSIM provider supports your OnePlus 7 model
• Dual SIM Slot: Ensure one SIM slot is available for the third-party eSIM adapter
