How to Install & Activate eSIM on iPhone
Ensure smooth and convenient connectivity on the go.
Summary
Set up your eSIM in just a few taps.
Installing an eSIM on your iPhone is quick, easy, and doesn’t require a physical SIM card swap. Whether you're switching plans, adding a travel eSIM, or managing multiple numbers, follow these simple steps to get connected:
- Open Settings
- Tap Mobile Service (or Cellular on some models)
- Select Add eSIM
- Choose to scan a QR code or manually enter the SM-DP+ address and activation code provided by your eSIM provider. The SM-DP+ address refers to the server that securely delivers your eSIM profile to your device.
Once the setup is complete, your iPhone will be ready to use the new data plan — no physical SIM needed.
In this guide, we’ll also walk you through what to do if your iPhone supports eSIM only, how to switch between multiple lines, and how to avoid common installation errors while travelling.
Is My iPhone Compatible With eSIM?
Most modern iPhones support eSIM, and for models sold in the US from the iPhone 14 onwards, it's the only option available — there's no physical SIM tray at all. But before you purchase a plan, it’s important to confirm whether your specific device supports eSIM and isn’t locked to a particular carrier.
To use an eSIM, your iPhone must meet the following requirements:
- eSIM-ready hardware: Your iPhone needs an Embedded Identity Document (EID) to support eSIM.
- Carrier unlocked: If your iPhone is carrier-locked, you might not be able to activate eSIMs from other providers.
Before you attempt to purchase and install an eSIM in your iPhone, remember to check your device’s eSIM compatibility. Doing so will save you time and ensure a smooth setup process.
Preparing For eSIM Installation on iPhone
To ensure a smooth eSIM setup on your iPhone, take a minute to get the following ready:
- Make sure you have a stable Wi-Fi or cellular network connection. This is essential for downloading and activating your eSIM profile.
- Have your QR code or activation URL readily available as you'll need this information during setup.
- Ensure your iOS device is updated to the latest software version, so as to avoid potential compatibility issues.
How to set up eSIM in iPhone
How Do I Install an eSIM Automatically on iPhone?
iOS devices now support automatic installation via a universal link. For example, if you’ve purchased an eSIM with Nomad, installation can be done within the app.
- On the Nomad iOS app, go to the “Manage eSIM” page.
- Select the eSIM you want to install and tap “Installation Instructions”.
- Choose the option to “Add automatically”, then tap “Install eSIM Now”.
- Follow the on-screen instructions to complete the installation.
How Do I Install an eSIM on iPhone Using a QR Code?
- Go to Settings > Cellular: This is the starting point for managing your iPhone's cellular plans.
- Initiate the QR code scanning process: Tap “Set up cellular” or “Add eSIM”, then tap “Use QR Code”: You might need to tap "Other Options" first.
- Scan the QR code: Position the iPhone to ensure that the code is clearly visible within the frame. For Nomad users, the QR code will be provided via in-app instructions and email.
How Do I Install an eSIM Manually on iPhone?
If scanning the QR code isn't working, you can manually enter the eSIM details. To do so:
- Tap "Enter Details Manually" instead of “Use QR Code”, and the screen will guide you through how to complete the installation on your iPhone.
If you’re a Nomad user, you can find the required information in your in-app instructions or purchase email.
Activating eSIM on iPhone
Installing your eSIM is only the first step — you’ll need to activate and configure it to start using mobile data.
- Automatic activation: Some eSIMs (like Nomad’s) activate automatically upon connecting to a local network. Just turn on the eSIM in your iPhone settings when you land — no extra steps needed.
- Manual activation: If your eSIM requires manual activation, do it while you still have internet access. Activation usually needs a stable connection, which may be harder to get once you’ve arrived.
For optimal setup:
- Set your primary number for calls, iMessage, and FaceTime
- Use the eSIM for cellular data only
- Keep “Allow Mobile Data Switching” off if you want to avoid accidental roaming charges
Troubleshooting eSIM Activation on iPhone
eSIM “No Signal” Issues
- Restart your iPhone: Turn your device off, wait a minute, and then turn it back on. This simple step often resolves minor software glitches.
- Update iOS: Make sure your iOS device is running on the latest software version. These updates often include bug fixes that can improve eSIM functionality.
- Check network coverage: eSIMs require a stable network connection to work. Verify that you're in an area with good coverage.
- Toggle eSIM settings: Go to Settings > Cellular, tap your eSIM data plan, and turn off "Turn On This Line." Wait a few seconds, then turn it back on.
- Toggle network selection: In the same settings page, turn off the "Automatic" network search. This forces your iPhone to scan for available networks manually.
Intermittent eSIM connectivity issues
Some users might encounter repeated connection drops with their eSIMs after activation, which can be disruptive. Here’s how you can troubleshoot the problem:
- Restart your iPhone: Power your device off, wait a minute, and then power it back on to refresh its network connection.
- Toggle Airplane Mode: Activate Airplane Mode for a few seconds, then deactivate it. Doing so can reset your iPhone's cellular connection.
- Check network selection: Ensure the correct carrier is selected in your network settings, as an incorrect selection can cause connectivity issues.
- Update iOS: Keeping your iOS software up-to-date is crucial for optimal performance and bug fixes. Make sure you're running the latest version.
- Toggle eSIM settings: Go to Settings > Cellular, tap your eSIM data plan, and toggle "Turn On This Line" off and then on again after a few seconds.
- Toggle network selection: In your cellular settings, try toggling off the "Automatic" network search so that you can manually select a network.
eSIM network compatibility issues
Sometimes, your eSIM might not be recognized or compatible with the cellular network provider you're trying to use. If you encounter this issue, first verify that your iPhone supports eSIM technology and that your chosen cellular network provider offers eSIM support.
Other than that, you can also:
- Check for carrier updates: Sometimes, carriers release updates necessary for eSIM compatibility. Find out if an update is available under Settings > General > About. If an update is available, you'll be prompted to install it.
- Reset network settings: This can sometimes resolve network configuration issues. Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. Be aware that this will erase saved Wi-Fi passwords, so you'll need to re-enter them.
- Contact your eSIM provider: Based on information such as your iPhone model, eSIM details, and the network that you’re trying to connect to, your carrier can help to diagnose the issue. They may reissue your eSIM or check for any network-specific issues in your area.
Primary line and secondary line switching issues
Unexpected switching between primary and secondary eSIMs on your iPhone can be frustrating. This situation often stems from incorrect eSIM settings, software glitches, or network problems. To address this issue, here are a few things you can try:
- Check primary SIM selection: Go to Cellular settings and ensure the correct eSIM profile is selected as your primary SIM. This designates which number is used for calls and texts.
- Verify primary eSIM designation: If you have multiple eSIMs, double-check that the eSIM you want to use as your primary line is correctly designated as such.
- Toggle automatic switching: Turn off and on the "Automatic" option for cellular data switching to help your iPhone prioritize the correct eSIM. However, do note that doing so may result in data roaming charges.

Can I use Dual eSIMs on my iPhone?
iPhones with eSIM support Dual SIM, allowing two numbers on one device. You can store multiple eSIMs and use two at the same time for seamless connectivity.
Depending on your iPhone model, these SIMs can be either physical or eSIMs. Here’s how you can use Dual SIM on iPhone:
- Label the plans: After activating both plans, label them to easily identify which number to use for different purposes, such as business, personal, and travel.
- Set default number: Choose a default number for calls and messages with people outside your contacts. This number also determines the cellular plan used for iMessage and FaceTime.
Dual SIMs are incredibly helpful, especially for travelers. With a Nomad eSIM, you can keep your original number active for calls and texts while using local data abroad — perfect for staying connected on the go.
