You can convert a physical SIM card to an eSIM if your phone and mobile carrier support the feature. On iPhone, open Settings > Cellular > Add eSIM and select your physical number. On Android, the option is usually under Settings > Network & Internet > SIMs or SIM Manager.
The exact steps vary by phone brand and carrier. Do not remove or discard your physical SIM until calls, texts, and mobile data work on the eSIM.
What You Need Before Converting to eSIM
Check these points before you begin:
- An eSIM-compatible phone
- A carrier that supports eSIM activation or conversion
- A stable Wi-Fi connection
- Your phone number and carrier-account verification details
- The latest available phone software update
- A charged phone or charger nearby
Your carrier may let you convert directly in settings, send a QR code, activate through its app, or require a visit to a store.
Important: Once the conversion is complete, your physical SIM normally becomes inactive. Keep it until you confirm that the eSIM is fully working.
How to Check if Your Phone Supports eSIM
Most recent flagship phones support eSIM, but availability can depend on the country and device model.
To check:
- Review the phone’s official specifications page.
- Search Settings for eSIM, Add eSIM, Set Up eSIM, or Download SIM.
- Ask your mobile carrier whether your exact phone model is supported.
Some phones support both a physical SIM and eSIM at the same time. Others allow several stored eSIM profiles but only a limited number of active lines.
How to Convert a Physical SIM to eSIM on iPhone
If your carrier supports direct conversion, follow these steps:
- Open the Settings app.
- Tap Cellular or Mobile Data.
- Tap Set Up Cellular or Add eSIM.
- Choose the phone number linked to your physical SIM.
- Select Convert to eSIM.
- Follow the on-screen instructions to confirm the conversion.
- Wait for the eSIM to activate.
- Test mobile data, calls, and SMS before removing the physical SIM.
On some iPhones, you may see Convert Cellular Plan instead. The wording can change slightly by iOS version and carrier.
If you do not see a conversion option, contact your carrier and ask for an eSIM activation QR code or an eSIM conversion request.
Transfer a SIM or eSIM to a New iPhone
When moving to a new iPhone, Apple may offer eSIM Quick Transfer during setup.
If you skipped it during setup:
- On the new iPhone, go to Settings > Cellular > Add eSIM.
- Choose Transfer From Nearby iPhone, if available.
- Keep both iPhones nearby with Bluetooth turned on.
- Confirm the transfer on your old iPhone.
- Wait for activation to finish.
- Test your number on the new device.
Your carrier may require a QR code or approval through its app instead. When the new eSIM activates, the previous SIM or eSIM for that line is normally deactivated.

Samsung menu names vary by model and One UI version, but the usual process is:
- Open Settings.
- Tap Connections.
- Select SIM Manager.
- Choose your physical SIM.
- Tap Convert to eSIM, if available.
- Complete the verification and activation steps.
If you do not see the option, tap Add eSIM and scan the QR code supplied by your carrier.
Activate an eSIM With a QR Code
Many carriers use a QR code instead of an in-phone conversion button.
- Ask your carrier for an official eSIM QR code.
- Connect the phone to Wi-Fi.
- Open the eSIM setup option in your phone settings.
- Select Use QR Code or Scan QR Code.
- Scan the carrier-provided code.
- Follow the activation prompts.
- Test calls, SMS, and mobile data.
Do not share your eSIM QR code publicly. It may be linked to your mobile plan and may only work once.
What to Do if “Convert to eSIM” Is Missing
A missing option does not necessarily mean your phone lacks eSIM support. Common reasons include:
- Your carrier does not support direct conversion
- Your carrier requires activation through its app or store
- Your device is running older software
- Your phone model or region does not support eSIM
- The phone is carrier-locked
- Your current plan does not support eSIM
Update your phone, restart it, and check your carrier’s official support page. If the option is still unavailable, contact carrier support and request an eSIM for your existing number.
eSIM Activation Problems: Quick Fixes
Try these steps if eSIM setup fails:
- Connect to reliable Wi-Fi
- Restart the phone
- Check for a software update
- Make sure the QR code has not already been used
- Confirm your phone is unlocked and eSIM-compatible
- Verify the phone’s IMEI or EID with your carrier
- Ask your carrier to resend or reissue the eSIM profile
Do not repeatedly delete and re-add an eSIM unless your carrier instructs you to do so. You may need a new activation code.
Benefits of Switching From Physical SIM to eSIM
eSIM offers several useful advantages:
- No tiny SIM card to insert, remove, or lose
- Easier activation when buying a new phone
- Support for a personal and work number on one device
- Convenient travel eSIM options
- More room for manufacturers to redesign phone hardware
- No need to wait for a physical SIM delivery in many cases
Things to Consider Before Switching
eSIM is convenient, but it is not always the best choice for everyone.
- Some carriers still have limited eSIM support.
- Moving an eSIM between phones can require carrier approval.
- A damaged or lost phone may make number recovery more complicated.
- Switching back to a physical SIM may require a new SIM card.
- International travel eSIM plans may have different data and calling rules.
If you change phones often, confirm your carrier’s eSIM-transfer process before converting.
Frequently Asked Questions
Can I convert my existing phone number to eSIM?
Yes, if your phone and carrier support eSIM conversion. In most cases, your existing number stays the same.
Will my physical SIM work after converting to eSIM?
Usually no. Once the eSIM activates, the physical SIM linked to that number is generally deactivated.
Can I use a physical SIM and eSIM together?
Many modern phones support dual SIM, allowing one physical SIM and one eSIM to be active together. The exact setup depends on the phone model.
Is eSIM better than a physical SIM?
eSIM is more convenient for many users, especially when switching phones or travelling. Physical SIM cards remain useful where carrier support is limited or when you frequently move a SIM between devices.
Can I transfer an eSIM from iPhone to Android?
Sometimes, but support depends on both devices and the carrier. If the phone’s transfer tool does not work, request a new eSIM profile from your carrier.
Final Thoughts
Converting a physical SIM to eSIM is simple when your carrier supports it. First check compatibility, connect to Wi-Fi, and use the conversion option in your phone settings or the carrier’s official QR code. Keep the old SIM until your number, mobile data, calls, and messages are working correctly.
