How to Install eSIM on iPhone

On an iPhone, an eSIM is installed through the cellular settings. After purchasing an eSIM, users typically receive a QR code or manual activation details. The profile can be added to the device in just a few minutes, after which it can be selected as the line for mobile data.

It is important to install the eSIM while connected to Wi-Fi or another stable internet connection. Once installed, the eSIM can be used during your trip, while your primary SIM card remains active for calls, text messages, and messaging apps.

Which iPhone Models Support eSIM?

eSIM technology is supported by most modern iPhone models.

Compatible devices include:

• iPhone XS and XS Max;
• iPhone XR;
• iPhone 11, 11 Pro, and 11 Pro Max;
• iPhone SE (2nd generation and newer);
• iPhone 12, 13, 14, 15, and newer models;

Before purchasing an eSIM, it is recommended to verify compatibility in your device settings or on Apple's official website.

What Do You Need Before Installation?

Before adding an eSIM, make sure you have everything required for activation.

You will need:

• a compatible iPhone;
• access to Wi-Fi or mobile internet;
• a QR code or manual activation details;
• the latest version of iOS;
• a few minutes to complete the setup.

It is also a good idea to save your QR code or activation information in case you need to reinstall the eSIM later.

How to Add an eSIM Using a QR Code

This is the easiest and most common method for installing an eSIM.

Follow these steps:

1. Open the Settings app.
2. Go to Cellular or Mobile Data.
3. Tap Add eSIM.
4. Choose the option to add a plan using a QR code.
5. Scan the QR code provided after purchase.
6. Confirm the installation of the cellular plan.
7. Wait for the activation process to finish.

Once completed, the new eSIM profile will appear in the list of available SIMs.

How to Add an eSIM Manually

If the QR code is unavailable or cannot be scanned, you can install the eSIM manually.

To do so:

1. Open Settings → Cellular.
2. Tap Add eSIM.
3. Choose the option to enter details manually.
4. Enter the SM-DP+ address and activation code provided by your carrier or eSIM provider.
5. Confirm the profile installation.
6. Wait for the setup process to complete.

After successful activation, the eSIM will be available for use on your device.

How to Select eSIM for Mobile Data

If multiple SIM cards are installed on your iPhone, you must choose which one will be used for mobile data.

To select your eSIM:

1. Open Settings.
2. Go to Cellular.
3. Tap Cellular Data.
4. Select your installed eSIM profile.

After this, all mobile data traffic will use the selected eSIM.

How to Enable Data Roaming

Some travel eSIM plans require data roaming to be enabled in order to connect to partner networks abroad.

To enable data roaming:

1. Open Settings.
2. Go to Cellular.
3. Select your eSIM profile.
4. Open Cellular Data Options.
5. Turn on Data Roaming.

Before traveling, check your eSIM provider’s instructions to confirm whether data roaming is required.

How to Remove an eSIM

After your trip or once your data plan has expired, you may want to remove the eSIM from your device.

To delete an eSIM:

1. Open Settings.
2. Go to Cellular.
3. Select the eSIM profile.
4. Tap Delete eSIM.
5. Confirm the action.

Before deleting the profile, make sure you no longer need it, as some providers do not allow the same eSIM to be installed again.

What to Do If the QR Code Won’t Scan

If your iPhone cannot recognize the QR code, there are several things you can try.

Check the following:

• make sure the entire QR code is visible to the camera;
• increase the screen brightness of the device displaying the QR code;
• connect to a stable internet connection;
• update iOS to the latest version;
• restart your iPhone;
• use manual installation with the SM-DP+ address and activation code.

If the problem persists, contact your eSIM provider’s support team.
