How to transfer SIM to eSIM?
To transfer your SIM to an eSIM, your phone must be compatible and your carrier must support the switch.
To transfer your physical SIM to an eSIM, you’ll need a compatible phone, an active mobile plan, and support from your carrier. Most major providers like Verizon, T-Mobile, and AT&T allow you to convert your SIM to eSIM through the settings app, a QR code, or by contacting customer support.
In this guide, we’ll explain what you need, how to transfer your SIM to an eSIM on both iPhone and Android, and where to get an international eSIM if you’re traveling.
Can I convert my existing SIM to an eSIM?
Yes, in most cases, you can convert your physical SIM card to an eSIM, as long as your phone and carrier support it. Today, most major mobile providers offer SIM-to-eSIM conversion, either through your phone’s settings or by contacting customer support.
Newer phones like the iPhone 14 and 15 no longer include a physical SIM slot, making eSIM the default option. However, even if your phone has a SIM tray, you can usually switch to eSIM by requesting it from your carrier.
Before starting, make sure:
- Your phone is eSIM compatible.
- Your carrier supports eSIM activation or SIM conversion.
Some carriers allow the switch instantly via a QR code or app. Others may ask you to contact support or meet additional requirements.
How to convert a SIM into an eSIM?
Changing from a regular SIM card to an eSIM is the same for many phone models overall. However, let’s take a look at how you can actually get the new eSIM on your phone.
How to Convert your SIM card to an eSIM on an iPhone
- On Apple devices, look for the settings menu.
- Tap on “Cellular” and then “Add Cellular Plan.”
- Choose the option to convert to eSIM. If it does not appear, your operator does not allow it.
- Select Convert Cellular plan.
- Finally, choose the activation method.
- Scan the QR code provided by your carrier, or enter the details manually.
- Follow the on-screen instructions to complete the setup.
Convert SIM to eSIM: Android
We also know that many brands use Android operating systems, sometimes adding layers of customization. Generally speaking, the process is the same; the names of the menus or their location in the configuration may vary slightly.
In the cleaner versions of Android, the process is as follows:
- Go to “Settings” on your Android device.
- Look for “Network & Internet” or a similar option.
- Select “Mobile network” and then “Advanced.”
- Choose “Carrier” and follow the instructions to add an eSIM.
How to convert SIM to eSIM on Samsung devices
Many Android devices on the market are from Samsung, so in this case, we will explain how to enter this menu on phones of this brand.
- Navigate to “Settings” on your Samsung device.
- Select “Connections” and then “SIM card manager.”
- Choose “Add mobile plan” and follow the prompts to scan the QR code or input the necessary information.
Do I have to go in-store to make this change?
Not necessarily. Once you’ve confirmed that your phone and carrier support eSIM, the next step is to check how your provider handles the activation process.
Most U.S. carriers, like T-Mobile and US Mobile, let you switch to an eSIM for the USA online, usually by scanning a QR code sent to your email. Others, such as Verizon, may require you to use their official app to complete the activation.
In countries like Canada, Freedom Mobile allows you to request and activate your eSIM through their website. In Europe, the process varies depending on the local carrier.
If you’re traveling or prefer to skip the carrier-specific steps, international eSIM providers like Holafly offer instant delivery and activation for over 200 destinations, without needing to visit a store or contact support.
Is there a fee for switching from a regular SIM to an eSIM?
In most cases, switching from a physical SIM to an eSIM is free, especially with major carriers in the U.S. and Europe. However, some providers may apply a small one-time activation fee, typically between $5 and $10.
Before starting the process, check directly with your carrier to confirm whether there’s a charge, how it will be billed, and if payment is required upfront or added to your next invoice.
Can I use an eSIM and a physical SIM at the same time?
Yes. Many smartphones today support Dual SIM functionality, meaning you can use both an eSIM and a physical SIM card simultaneously. This is especially useful if you want to keep your local number active while using a second line for data during international travel.
Some newer phones (like the iPhone 14, 15, and newer in the U.S.) support only eSIM and no longer include a physical SIM tray. But for most devices, having both options is still common.
If you’re traveling and want to avoid roaming fees, you can use your regular SIM for calls and get a digital SIM from an international provider like Holafly for data. It’s a convenient way to stay connected without switching numbers or dealing with local SIM cards.

Frequently Asked Questions about how to transfer a SIM to an eSIM
When you convert your SIM to an eSIM, your physical card is replaced by a digital version stored on your phone. You’ll no longer need to insert or carry a plastic SIM, and you can manage your cellular plans directly through your device’s settings.
If your phone supports Dual SIM, you can switch between SIM and eSIM in your mobile network settings. Just choose which line you want to use for data, calls, or texts. Switching is instant, but double-check which one is active to avoid unexpected charges.
A SIM is a removable plastic card that stores your mobile data and connects you to your carrier. An eSIM is the digital version built into your phone. It lets you switch carriers or plans without changing cards—ideal for frequent travelers.
It usually takes just a few minutes. Some carriers let you instantly complete the switch using a QR code or their official app. Others may require a short activation window or customer support interaction. In most cases, you can do it in under 10 minutes.
That depends on your carrier. Some providers allow you to mirror your physical SIM number onto an eSIM (known as number sharing), while others treat each SIM/eSIM as a separate line. Contact your carrier to confirm if this feature is available for your plan.
