Activating an eSIM on an iPhone is a simple process that replaces the need for a physical SIM card. You can activate it by going to Settings > Cellular > Add eSIM, then choose how you want to set it up—either by scanning a QR code provided by your carrier or by manually entering the activation details like the SM-DP+ Address and Activation Code. Once added, follow the on-screen instructions to finish activation. Make sure you’re connected to Wi-Fi or mobile data during setup. If you’re switching from a physical SIM, your iPhone may also offer the option to convert it to an eSIM directly.
Key Takeaways

What Is an eSIM and How Does It Work on iPhones?
An eSIM (short for embedded SIM) is a digital version of the traditional SIM card that’s built directly into your iPhone. Instead of inserting a small plastic card to connect to your mobile network, your iPhone uses software to download and activate your carrier plan. This makes switching carriers or adding new lines much faster—no need to visit a store or wait for a SIM card in the mail.
On iPhones, eSIM works by securely storing carrier details in the phone’s internal chip. When you activate an eSIM, it behaves just like a physical SIM, giving you access to talk, text, and data over your carrier’s network. Many newer iPhones support dual SIM functionality, meaning you can use both a physical SIM and an eSIM—or even two eSIMs—on one device.
eSIM vs. Physical SIM – What’s the Difference?
| Feature | Physical SIM | eSIM (Embedded SIM) |
|---|---|---|
| Form | Removable plastic card | Built into the phone’s hardware |
| Setup | Insert SIM manually | Activated through software |
| Switching carriers | Requires swapping SIM cards | Can switch via QR code or carrier app |
| Dual SIM support | 1 physical + 1 eSIM on most iPhones | 2 eSIMs on newer iPhones (no physical slot) |
| Availability | Universally supported | Requires carrier eSIM support |
eSIMs offer greater flexibility and convenience, especially for frequent travelers or users who want to keep personal and work numbers on the same device.

Things to Do Before You Activate eSIM on iPhone
Before jumping into the eSIM setup process, it’s smart to make sure your iPhone and carrier are ready. Activating an eSIM only takes a few minutes, but missing one key detail—like using a locked phone or the wrong setup method—can delay everything. Here’s what to check first:
Is Your iPhone Unlocked?
Your iPhone needs to be unlocked to use an eSIM from a different carrier. If the phone is still locked to its original network, you may only be able to activate an eSIM from that same provider.
How to Check SIM Lock Status:
- Open Settings
- Tap General > About
- Scroll to Carrier Lock
- If it says “No SIM restrictions,” your iPhone is unlocked
- If it lists a carrier, your phone may still be locked
If your iPhone is locked, contact your carrier to request an unlock. Most carriers will unlock your phone for free if it’s fully paid off and your account is in good standing.
Does Your Carrier Support eSIM?
Not all carriers offer eSIM service, so it’s important to verify this before setup. Fortunately, most major U.S. carriers now support eSIM on compatible iPhones.
U.S. Carriers That Support eSIM:
- AT&T
- T-Mobile
- Verizon Wireless
- Visible (by Verizon)
- Mint Mobile
- Cricket Wireless
- Google Fi
- US Mobile
- Xfinity Mobile
- TracFone / Straight Talk (select plans)
If you’re using a smaller carrier or an MVNO (Mobile Virtual Network Operator), check their website or contact customer support to confirm eSIM availability.

Do You Have a QR Code, App, or Manual Setup Info from Carrier?
Activating your eSIM requires information from your carrier. This could come in the form of a QR code, a carrier app, or manual setup instructions (such as a SM-DP+ address and activation code).
🔍 What You’ll Need for Activation:
- A QR Code (usually sent by email or displayed in-store)
- Or access to your carrier’s mobile app (Verizon, AT&T, etc.)
- Or manual setup details, including:
- SM-DP+ Address
- Activation Code
- Confirmation Code (optional)
If you’re unsure what method your carrier uses, contact their customer service team or visit their website’s eSIM activation section. Some carriers even allow you to generate your own eSIM profile directly from their app.
Quick Tip: Make sure your iPhone is updated to the latest version of iOS and is connected to Wi-Fi or mobile data before beginning the activation process. This will ensure a smooth and fast eSIM setup.
How to Activate eSIM in iPhone (3 Methods)
You can activate your iPhone’s eSIM in a few different ways, depending on what your carrier supports. Whether you received a QR code, plan to use your carrier’s app, or need to enter info manually, here’s a clear step-by-step guide for each method.
Method 1: Activate eSIM Using Carrier QR Code
Most common method used by major carriers
- Open the Settings app on your iPhone.
- Tap Cellular (or Mobile Data depending on region).
- Tap Add eSIM or Add Cellular Plan.
- Select Use QR Code.
- Use your iPhone’s camera to scan the QR code provided by your carrier.
- Follow the on-screen prompts to:
- Confirm adding the plan
- Label the line (e.g., Primary, Business, Travel)
- Set default line for calls, messages, and data
- Wait for the phone to activate the eSIM and show signal bars. You’re now ready to use your eSIM!
📌 Tip: If scanning the QR code doesn’t work, try increasing brightness or printing the QR for better visibility.
Method 2: Activate eSIM via Carrier App (AT&T, T-Mobile, Verizon)
Convenient for users who prefer in-app control and already have an account
- Download your carrier’s official app from the App Store:
- Open the app and sign in with your account credentials.
- Navigate to “Activate or Set Up Device” or similar option in the menu.
- Select eSIM Activation and follow the instructions provided in the app.
- This may include verifying your device IMEI
- Some carriers allow you to activate with just a tap
- Wait for the plan to be added automatically.
- You’ll see the new line in Settings > Cellular
Note: This method usually works only if you’re already an existing customer or if the phone was purchased through that carrier.
Method 3: Manual Activation with SM-DP+ Address and Activation Code
Use this when no QR code or app is available—especially for enterprise or international eSIM setups
- Open the Settings app on your iPhone.
- Tap Cellular > Add eSIM or Add Cellular Plan.
- Select Enter Details Manually instead of scanning.
- Enter the following fields exactly as provided by your carrier:
- SM-DP+ Address (eSIM server)
- Activation Code
- Confirmation Code (optional, depends on carrier)
- Tap Next and wait for the iPhone to verify and activate the eSIM plan.
- Label the plan and set preferences for calls, messages, and data use.
📌 Reminder: These details are typically emailed to you by the carrier or available through your carrier’s website portal.
Each of these methods will activate your eSIM successfully if your carrier supports eSIM and your device is compatible. Always keep Wi-Fi or mobile data enabled during the process. If you face issues, contact your carrier’s support team for assistance.
Dual SIM Setup: Use eSIM Alongside Physical SIM (or Two eSIMs)
Apple’s Dual SIM feature lets you use two phone numbers on a single iPhone—perfect for managing personal and work lines, or for using a local carrier while traveling. With the latest iPhone models, you can either combine an eSIM with a physical SIM, or use two active eSIMs on devices like the iPhone 14, 15, and 16 series (U.S. models are eSIM-only).
Once both plans are added, your iPhone allows you to label each line to avoid confusion. During setup, you’ll be prompted to assign labels such as Primary, Secondary, Personal, Business, or create a custom name. These labels appear in your Contacts, Messages, and Call logs so you always know which number you’re using.
When it comes to calls and texts, your iPhone allows you to choose a default line for iMessage, FaceTime, and voice calls. You can set one line as the default for outgoing communications, while still receiving calls and texts on both lines. If someone calls either number, your iPhone will ring normally—unless you’re already on a call, in which case only the active line will work (this depends on carrier support for Dual SIM Dual Standby).
For cellular data, you’ll also need to select which line to use for mobile internet. Go to Settings > Cellular > Cellular Data and choose the line you want to use for data. If you’re traveling or switching data plans, you can change this setting anytime. There’s also an option called “Allow Cellular Data Switching,” which enables your phone to automatically switch lines for better coverage, but only when you’re on a call using the voice-only line.
Using Dual SIM on iPhone is seamless and ideal for people who want to keep work and personal life separate, or travelers who need two networks without carrying two phones.

Troubleshooting eSIM Activation Issues on iPhone
Even though activating an eSIM on an iPhone is usually a smooth process, a few common issues can sometimes get in the way. If your iPhone shows “No Service,” fails to scan the QR code, or the eSIM option doesn’t appear in Settings, here’s how to troubleshoot and get things working again.
No Service” or “Invalid Activation Code”
If you’re seeing “No Service” after setting up your eSIM or an error saying “Invalid Activation Code,” it likely means your carrier isn’t connecting properly. Start by double-checking that your carrier supports eSIM and that your iPhone is unlocked if you’re using a different provider than the one it came with.
Make sure you’re connected to a stable Wi-Fi or cellular data network during activation. A weak or interrupted connection can cause the process to fail. If you received your QR code or activation details by email, make sure the info wasn’t altered or copied incorrectly. You may also need to contact your carrier to verify that your eSIM profile is still valid and has not expired or been used on another device.
QR Code Not Scanning?
If your iPhone isn’t recognizing the QR code provided by your carrier, try a few basic fixes. Increase the brightness on your printed code or computer screen, and make sure the QR code is clearly visible and not distorted. If printed, avoid folds or glare on the paper.
Also, make sure your iPhone camera lens is clean and free of smudges, as even a small smudge can prevent the scanner from reading the code properly. If the problem continues, ask your carrier to resend the QR code or provide manual activation details.
eSIM Option Not Showing in Settings?
If you don’t see the “Add eSIM” or “Add Cellular Plan” option in your iPhone’s Cellular settings, first confirm that your iPhone model supports eSIM. Models from iPhone XR/XS and newer are generally compatible, but eSIM features vary slightly by region and carrier.
Also, check for any available iOS updates by going to Settings > General > Software Update. Sometimes, a pending update can block access to certain features. If your iPhone is updated and still doesn’t show the eSIM option, try restarting the device or resetting network settings by going to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings.
If none of these steps work, your best next move is to contact Apple Support or your carrier for direct assistance. Many carriers can push a new eSIM profile to your device remotely.
How to Transfer eSIM from Old iPhone to New iPhone
When upgrading to a new iPhone, you don’t have to visit a store or request a new SIM card. Apple makes it easy to move your eSIM from one iPhone to another with a built-in transfer tool. Depending on your carrier’s support, you can either use Apple’s “Transfer from Nearby iPhone” feature or re-activate the eSIM using your carrier’s app or a QR code. Here’s how both methods work.
Use “Transfer from Nearby iPhone” Option
If both your old and new iPhones are running iOS 16 or later and your carrier supports eSIM transfer through Apple, you can use this method to wirelessly move your eSIM in just a few taps.
- On your new iPhone, go to Settings > Cellular > Add Cellular Plan.
- Select “Transfer from Nearby iPhone” when prompted.
- Make sure Bluetooth and Wi-Fi are enabled on both iPhones.
- Your old iPhone will show a message asking you to approve the transfer. Tap Transfer.
- Follow the on-screen instructions to finish the process.
Once the eSIM is transferred, it will be deactivated on the old phone and ready for use on the new one. This process is safe and quick, but only works if your carrier allows eSIM migration via Apple’s system.
Re-activate eSIM via Carrier App or QR
If your carrier doesn’t support eSIM transfer through Apple’s method, don’t worry. You can still move your eSIM by contacting the carrier or using their self-service tools.
Option 1: Carrier App
Download your carrier’s app (like My Verizon, AT&T, or T-Mobile). Sign in and look for options like Activate eSIM, Transfer Line, or Replace Device. You may be able to set up the new phone without talking to support.
Option 2: Use a New QR Code
Many carriers allow you to request a fresh eSIM QR code. Once received, scan it on the new iPhone by going to Settings > Cellular > Add eSIM > Use QR Code. If necessary, delete the old eSIM from your previous phone to avoid connection issues.
Note: Not all carriers allow multiple eSIM activations for the same line, so some may require you to call or chat with support to manually reset or release the eSIM from your old device. Always back up your iPhone before making changes, just in case.
Whether you use the quick-transfer method or reactivate manually, transferring an eSIM to a new iPhone is now easier than ever.
eSIM Activation for International Travel – What You Should Know
One of the best features of an eSIM is the ability to use international mobile data without swapping SIM cards or carrying a second device. If you’re traveling abroad with an iPhone that supports eSIM, you can stay connected affordably and conveniently while still keeping your U.S. number active. Here’s how to make the most of your iPhone’s eSIM for international travel.
Use eSIM for International Data While Keeping Your U.S. Number
When you’re overseas, you don’t need to give up your primary U.S. number. Instead, you can keep your U.S. line on your physical SIM or existing eSIM and add a second travel eSIM just for data. This means you’ll still receive texts and calls on your U.S. number (great for two-factor authentication or urgent contacts), while browsing and using apps with a local or global data plan.
Apps like Airalo, Nomad, and GigSky make this simple. You can purchase and install a travel eSIM before you even leave the country. These eSIMs are data-only, so you won’t get a new phone number—but they’re ideal for maps, browsing, messaging apps, and social media on the go.
To use both lines:
Go to Settings > Cellular > Cellular Data and choose the travel eSIM for data usage
Set your U.S. number as the default for calls and messages
Make sure Data Roaming is turned off for your U.S. line to avoid extra charges
This dual setup gives you the flexibility to travel smarter and more connected without juggling SIM trays or roaming fees.
Top eSIM Providers for Global Roaming
There are several trusted eSIM providers that specialize in international coverage. Here’s a quick comparison of the most popular options for iPhone users:
| Provider | Key Features | Pricing (Starts At) | Coverage | Setup Process |
|---|---|---|---|---|
| Airalo | Pay-as-you-go plans in 200+ countries | ~$4.50 for 1GB | Global | App-based install, instant QR |
| Holafly | Unlimited data in select regions | ~$19 for 5 days | 130+ countries | Email QR code, 24/7 support |
| Ubigi | Flexible prepaid plans | ~$9 for 1GB | 190+ countries | Manual or QR activation |
- Airalo is great for budget-conscious travelers who just need a little data.
- Holafly is ideal for heavy users wanting unlimited data without worrying about limits.
- Ubigi offers a balance of coverage and flexibility, and even works with some vehicles and tablets.
Each of these providers lets you purchase a plan from your iPhone, install the eSIM directly, and activate it once you land. That means you’ll have service the moment your plane touches down—no airport SIM shops required.
Using eSIM for international travel is one of the smartest ways to stay online, navigate new cities, and stay in touch—without surprise roaming charges. Just install your travel eSIM ahead of time, set it as your data line, and you’re ready to explore with confidence.
How to Remove or Replace an eSIM on iPhone
Removing or replacing an eSIM on your iPhone is simple and takes just a few steps. Whether you’re switching carriers, upgrading to a new plan, or resolving a connection issue, managing your eSIM settings is entirely in your control. Below are the steps to safely delete or swap out your eSIM.
Steps to Delete an eSIM
If you’re no longer using an eSIM or need to clear it before setting up a new one, you can delete it directly from your iPhone’s settings.
- Open the Settings app
- Tap Cellular (or Mobile Data)
- Locate and select the eSIM line you want to remove
- Scroll down and tap Remove Cellular Plan
- Confirm your choice when prompted
Once removed, the eSIM will be erased from your device, and that cellular line will no longer appear in your settings. This is a good option if you’re done with that plan or switching to another provider.
Note: Deleting an eSIM does not cancel your service—you’ll still need to contact your carrier to stop billing unless it’s a prepaid plan.
Replacing eSIM with New Carrier or Plan
If you’re changing mobile carriers or switching to a new eSIM plan, you’ll need to repeat the eSIM activation process using a new QR code, carrier app, or manual setup.
Go to Settings > Cellular > Add eSIM, and follow the prompts to activate the new plan. Depending on your carrier, this may require you to scan a new QR code or enter activation details manually. Some carriers also allow you to set up a replacement eSIM directly through their app, especially if you’re upgrading to a new iPhone or switching plans.
Keep in mind that an eSIM can only be active on one device at a time. If you’ve used the eSIM on a previous phone, you may need to contact your carrier to release or reset it before reactivating it on another device.
Managing your iPhone’s eSIM is flexible and user-friendly. Whether you’re removing an old plan or setting up a new one, the process is secure, fast, and doesn’t require handling a physical SIM card.
