eSIM QR code: What it is and how to get it

What is an eSIM QR code?

An eSIM QR code is a machine-readable code that lets your device download and activate a digital SIM profile. It replaces the need for a physical SIM card by linking your phone directly to your mobile carrier through a secure digital process.

When scanned, this QR code delivers essential carrier information to your phone, such as authentication credentials and network settings. The setup is usually completed within a few minutes.

This method is especially useful for travelers, remote workers, and anyone looking for a flexible and virtually-enabled mobile solution.

The eSIM QR code usually contains:

• Carrier network information
• SM-DP+ address (used to download the eSIM profile)
• Activation code linked to your plan

Why do you need an eSIM QR code?

Before activating your eSIM, you’ll need a QR code from your mobile provider. This code is the key to installing your eSIM profile onto your device. Without it, the activation process cannot begin.

Most providers send the eSIM QR code via email or show it in your account dashboard after purchase. Once scanned, it securely delivers your plan settings and links your phone to the correct network.

Using a QR code makes eSIM setup:

• Quick: No need to visit a store or wait for delivery
• Digital: Everything is handled online
• Reliable: Minimizes manual errors during activation
• Convenient: Ideal for frequent travelers and dual-SIM users

The eSIM QR code is essential because it bridges your device and the carrier’s system.

What to prepare before getting your eSIM QR code

Before requesting an eSIM QR code, it’s important to ensure your device and account are ready. Missing just one step could cause delays in activation or lead to errors. Here’s what to check first.

Check if your device supports eSIM

An eSIM only works if your phone or tablet supports the technology. Many newer models from Apple, Samsung, Google, and others are compatible, but older or locked devices may not be.

You can check compatibility in several ways:

• Go to your device settings → Cellular or Mobile Network → Look for an option to Add eSIM or Add cellular plan.
• Visit the official website of your phone brand and search the model name + eSIM support
• Contact your mobile provider to confirm eSIM capability

Keep in mind: Some devices may support eSIM in hardware but are disabled by the carrier or region. Unlocked phones usually work best.

Get your IMEI number ready

Some eSIM providers require your IMEI when registering or issuing the QR code. This unique number helps link the eSIM profile directly to your device and prevents fraud or duplication.

To find your IMEI:

• Dial *#06# and the number will appear automatically
• Or go to Settings → About Phone → IMEI

Note: You may see two IMEIs on dual-SIM phones. Use the one linked to the eSIM slot or as advised by your provider.

Having this number ready ensures faster processing when buying or activating an eSIM.

Troubleshooting eSIM QR code issues

Sometimes, scanning the QR code doesn’t go smoothly. Common issues include unsupported devices, expired QR codes, or network interruptions during activation.

Here’s how to troubleshoot:

• Double-check that your device is eSIM-compatible and unlocked

• Confirm the QR code hasn't expired (some only work for 24–48 hours)
