How to Convert Physical SIM to eSIM on iPhone & Android

Want to get rid of your plastic SIM card without changing your phone number? You may be able to do that in a few minutes.

You can convert a physical SIM to eSIM when your phone, carrier and mobile plan support the process. Your existing number and subscription normally stay the same. Only the way your phone connects to the network changes.

But there is a catch. An eSIM-compatible phone does not guarantee that your carrier allows direct conversion.

Some providers offer a conversion button in your phone's settings, while others require their app, a QR code or customer support. And do not confuse converting your SIM with installing a travel eSIM.

They are two different things. A successful conversion also normally deactivates your old physical SIM, so check everything before discarding it.

In this article, you will learn how you can convert the traditional SIM into eSIM and keep your number active and stay connected with eSIMCard.

Can You Convert a Physical SIM to a Digital SIM?

Yes, you can convert a traditional SIM to digital SIM if your device and carrier support it. The process moves your existing mobile service from a physical SIM card to a digital eSIM profile.

Your phone number, carrier and plan normally remain unchanged. However, your provider must approve the conversion for your particular account and mobile line.

Before you begin, check four things:

Your phone supports eSIM in your country or region.
Your carrier allows conversion of your existing SIM.
Your account and plan qualify for the service.
Your phone's software supports the required activation method.

For iPhones, eSIM support starts with the iPhone XS, and iPhone XR or later models, subject to regional restrictions. The iPhone X doesn't support eSIM.

Samsung Galaxy and Google Pixel phones have different compatibility requirements. Even when your phone supports eSIM, your carrier may not offer a direct conversion option.

Before starting the conversion process, check our list of eSIM-compatible devices to confirm whether your iPhone or Android smartphone supports eSIM technology.

Convert vs Transfer vs Add eSIM: What's the Difference?

This is where many people get confused. The options sound alike, but each one serves a different purpose.

Process	What Happens?	Does Your Number Stay the Same?
Convert physical SIM to eSIM	Your existing line moves to an eSIM on the same phone.	Usually yes
Transfer SIM to a new phone	Your existing service moves to another device.	Usually yes
Add a carrier eSIM	You add another mobile plan.	Depends on the plan
Install a travel eSIM	You add a separate travel connectivity plan.	Your home number remains separate

Imagine you have used a physical SIM from your home carrier for years. You want to keep your number but stop using the plastic card. That's a conversion.

Now imagine you have bought a new phone and want your existing number on it. That's a transfer, which may require a different process.

A travel eSIM is different again. It gives you a separate plan for mobile data abroad. It doesn't convert your home SIM or automatically move your existing number.

Before You Convert Your Physical SIM to eSIM

A little preparation can save you from an awkward situation with no working phone service.

Start by checking your phone model and your carrier's conversion policy. If you cannot find clear information online, contact the provider before changing your SIM.

You will also want reliable Wi-Fi if your device or carrier requires it. Update your phone if needed, sign in to your carrier account and keep any required identity verification details nearby.

Some providers ask for your phone's EID, a device identifier used during eSIM provisioning. Your carrier can explain where to find it and whether you need it.

Keep your physical SIM in the phone until you are ready to follow the conversion instructions. Do not cancel your line or delete an existing eSIM profile while preparing.

How to Convert Physical SIM to eSIM on iPhone

Apple provides a built-in conversion option on supported iPhones and networks. The exact menu names can vary with your iOS version and carrier.

Follow these steps:

Open Settings on your iPhone.
Tap Cellular or Mobile Service.
Select Set Up Cellular or Add eSIM, depending on the options shown.
Choose the number currently using your physical SIM.
Tap Convert to eSIM if the option appears.
Follow the on-screen instructions to complete activation.

If you do not see Convert to eSIM, your carrier may require another activation method. Contact the provider before assuming your phone is incompatible.

Once activation finishes, the physical SIM normally stops working. Test calls, SMS and mobile data before treating the conversion as complete.

How to Convert Physical SIM to eSIM on Samsung Galaxy

On supported Samsung Galaxy phones, you may be able to convert your physical SIM directly through SIM manager.

Here is the usual route:

Open Settings.
Tap Connections.
Select SIM manager.
Choose the physical SIM you want to convert.
Tap Convert to eSIM, if available.
Confirm the change and follow the instructions.

The option depends on your Galaxy model, software and mobile provider. If it is not there, ask your carrier whether it supports conversion through an app, QR code or customer service.

Do not choose Add eSIM assuming it will convert your existing number. That option may start the process of adding a separate mobile profile instead.

How to Convert Physical SIM to eSIM on Google Pixel

Supported Google Pixel phones may offer a Convert to eSIM option in their SIM settings. Availability depends on your model, software and carrier.

To check:

Open Settings.
Tap Network & internet.
Select SIMs.
Choose the physical SIM you want to convert.
Scroll down and look for Convert to eSIM.
Check on-screen instructions if the option is available.

What If Your Carrier Doesn't Show Convert to eSIM?

A missing button does not necessarily mean your phone lacks eSIM hardware. Your carrier may simply use another activation method.

What You Notice	Possible Reason	What to Do
Phone doesn't support eSIM	Unsupported model or regional variant.	Check your manufacturer's compatibility information.
eSIM works, but conversion is missing	Carrier doesn't support direct conversion.	Contact your carrier.
Carrier asks for a QR code	Different activation process required.	Request the correct activation details.
Account doesn't show the option	Eligibility or identity verification issue.	Sign in as the account owner or contact support.
Settings look different	Software version or menu differences.	Check for updates and current instructions.
Activation fails halfway	Carrier network provisioning problem.	Check the line status before retrying.

Some carriers allow conversion through their own apps. Others require a QR code, manual activation or an in-store visit.

For example, Telstra customers can follow Telstra's SIM conversion policy to switch their physical SIM to an eSIM using the My Telstra app without changing their mobile number.

Does Your Number and Plan Stay the Same?

A direct physical SIM to eSIM conversion normally keeps your existing number and mobile plan. Your carrier changes the SIM format linked to your line.

Your carrier, account, phone number and subscription generally remain the same. However, individual providers may have different eligibility rules or account requirements.

If keeping your number is your main concern, ask your carrier to confirm that the process is a direct conversion. You don't want to accidentally order a new line when you intend to keep your current one.

What Happens to the Physical SIM After Conversion?

Once the eSIM activates successfully, your old physical SIM normally becomes inactive. It won't usually work as a backup copy of the same number.

Keep the card until you've checked that your eSIM works. Then store or dispose of it securely, rather than assuming you can use it again later.

Test an outgoing call, an incoming call, SMS and mobile data. If you rely on verification texts for banking or work accounts, check those too.

If you want to return to a physical SIM later, your carrier may need to issue a replacement card. Reinserted old SIM cards don't automatically regain service.

How to Transfer Your SIM to eSIM on a New Phone

If you have bought a new phone, you may need to transfer your existing service instead of converting the SIM on your current device.

Devices	Possible Method	What to Check
iPhone	eSIM Quick Transfer	Device compatibility and carrier support
Google Pixel	Supported SIM transfer or carrier activation	Model, software, and carrier eligibility
Samsung Galaxy	Supported transfer feature or carrier activation	Galaxy model and provider requirements
Other phones	Carrier app, QR code, or customer support	Your provider's specific instructions

Apple's eSIM Quick Transfer can move an eligible mobile line between supported iPhones. It iss separate from converting a physical SIM on the same device.

Google and Samsung also support transfer methods in certain situations. The available process varies by phone and carrier.

Don't erase or trade in your old phone until your new one has working service. Check calls, messages and data first, especially if you use your number for two-factor authentication.

How to Switch From eSIM Back to Physical SIM

Many carriers let you switch back, but you may need their help.

Contact your provider and ask for a physical SIM replacement. Confirm whether a fee applies and how the new card will be activated.

Once you receive the replacement, follow the carrier's instructions and test your service. Don't assume the original physical SIM will work again after conversion.

Convert to eSIM Not Working? Try These Fixes

A failed conversion can be stressful when your number is tied to work, banking or account verification. Check what happened before making further changes.

Problems	What to Try
Convert to eSIM option missing	Check device compatibility, carrier support, and account eligibility.
Activation is stuck	Keep Wi-Fi connected if required and verify line status with your carrier.
Physical SIM stopped, but eSIM has no service	Restart your phone and check network registration.
eSIM appears, but calls/SMS fail	Confirm the correct line is enabled and contact your carrier.
QR code won't scan	Check carrier instructions or request a replacement code.
eSIM was deleted accidentally	Ask your carrier to restore or reissue the profile.
Service isn't working on a new phone	Check whether you need a transfer instead of a conversion.

If activation gets stuck

Check whether the eSIM appears in your phone's SIM settings. Give the phone time to register on the network, then try toggling Airplane Mode or restarting the device.

Do not repeatedly delete and reinstall the profile. Your carrier may already have started activating the line.

If service does not return, contact your carrier using another phone or an online support channel. Ask whether the conversion completed on its network and whether the eSIM needs restoring.

If you have accidentally deleted the profile, your provider may need to issue a new activation code. Do not assume your original QR code can be reused.

If you need a separate travel data plan instead of converting your existing SIM, follow our guide on how to get an eSIM to understand the purchasing and installation process.

Is It Worth Switching to eSIM While Traveling?

Whether you want to change your home SIM or get cheaper mobile data abroad.

In most cases, switching your home SIM to an eSIM keeps your current service.

It does not automatically erase international roaming charges or give you a local travel data bucket. A separate travel eSIM could be better for trips abroad. You can install a prepaid data plan for your destination and keep your home line open.

If you're travelling internationally, explore eSIMCard's Global eSIM plans for flexible prepaid mobile data across supported destinations.

Before you travel, check that your phone is unlocked (if needed) and supports eSIM. Set the correct line for mobile data, and check your roaming settings so you do not get any surprises.

You can browse the eSIM plans for travel to the destinations we support with eSIMCard. These plans offer standalone connectivity and will not convert your existing home carrier SIM or port your phone number.

No roaming bill waiting at home

Pay once for local data rates in 200+ countries and leave expensive roaming behind.

Conclusions

Check your carrier’s policy before converting your physical SIM, and make sure your device supports the process.

One simple step can save you from an avoidable loss of service. For mobile data for an upcoming trip, check out eSIMCard's travel eSIM plans.

Select a plan for your destination, and keep your home number separate from your travel data service.
