An eSIM is a digital version of a traditional SIM card that lives inside your phone rather than as a physical chip you can remove or swap. The term stands for "embedded SIM," and it's become standard on most modern smartphones released since 2018. Instead of a tiny card with metal contacts, your phone's eSIM stores your carrier information—the data that tells the network who you are and which plan you're using—in digital form on a special chip built into the device itself.

Unlike the old plastic SIM cards that physically moved between phones, an eSIM is tied to your device through software. This means transferring your service to a new phone requires a different process than just popping out a card and putting it in another device. The good news is that moving an eSIM is not complicated once you understand the basic steps and what your carrier needs from you.
People switch phones for many reasons. Your current phone might be aging and slowing down, the battery may no longer hold a charge through a full day, or you might be upgrading to a newer model with better features. Sometimes people switch from Android to iPhone or vice versa. Other times they're simply moving to a device with a larger screen, better camera, or longer battery life. Whatever the reason, your eSIM doesn't stay on the old phone—it's designed to move with you.
The process works differently depending on whether you're moving to a new phone from the same manufacturer (like iPhone to iPhone) or switching brands entirely (like Samsung to iPhone). Some carriers make this process more straightforward than others. Major carriers like Verizon, AT&T, T-Mobile, and many regional carriers now support eSIM transfers, though the exact steps vary slightly between them.
Key takeaway: An eSIM is a digital carrier profile stored on your phone, not a physical card. When you get a new phone, you need to transfer or reactivate that profile on your new device through your carrier's system.
Before you can move your eSIM, your new phone must actually support eSIM technology. This isn't the case for every phone on the market, though it's becoming increasingly common. If you buy an older refurbished model or a budget phone from several years ago, it might not have eSIM capability at all.

For iPhones, eSIM support began with the iPhone XS, XS Max, and XR models released in 2018. Every iPhone model since then, including the entire iPhone 11, 12, 13, 14, 15, and 16 lineups, supports eSIM. If you have any of these models, you're good. Older iPhones like the 8, 8 Plus, and X do not have eSIM capability, though they do have physical SIM card slots.
For Android phones, the situation is more varied. Samsung's flagship Galaxy S20 and newer models support eSIM. Google's Pixel phones starting with the Pixel 3 support eSIM, as do most recent Pixel models including the Pixel 6, 7, and 8 series. However, not all mid-range or budget Android phones have eSIM capability. OnePlus, Motorola, and other manufacturers have gradually added eSIM support to their newer flagships, but their older or budget models often don't have it.
To check your specific phone model, visit the manufacturer's official website or check the phone's technical specifications. Search for your phone model name plus "eSIM support" to find official documentation. Your carrier's website may also list compatible phones, though manufacturer specs are more reliable. When buying a new phone, whether from a carrier store, retailer, or private seller, confirm the model supports eSIM before making the purchase.
Some phones also come in different versions—certain models sold in specific regions or through certain carriers might have a physical SIM slot only, while the same model sold elsewhere has eSIM. This is less common now but still happens with some international phone models.
Key takeaway: Check your new phone's specifications on the manufacturer's website to confirm eSIM support before attempting any transfer. Most iPhones since 2018 and recent flagship Android phones support eSIM, but older or budget models often don't.
Your wireless carrier controls whether your eSIM can be transferred to a new device, and you'll need to work with them to make it happen. This is true whether you're using Verizon, AT&T, T-Mobile, a regional carrier, or even a mobile virtual network operator (MVNO) that borrows network infrastructure from a major carrier.

Before contacting your carrier, gather some information. You'll need your phone number, account number or PIN, and ideally your old phone still available with the eSIM on it. Have your new phone ready as well, though you may not need it immediately. Different carriers handle eSIM transfers in different ways, so calling ahead prevents wasted time.
Most major carriers offer multiple ways to reach them: phone, online chat, visiting a physical store, or using their mobile app. For eSIM transfers specifically, a phone call or in-person store visit often works better than chat, since the representative needs to verify your identity and access your account details. When you call, be clear that you want to transfer your eSIM to a new device, not cancel service or make other changes.
During the call, the carrier representative will verify you're the account holder by asking security questions or confirming personal details. They'll then deactivate the eSIM on your old phone and either provide you with a QR code to scan on your new phone, send you a download link, or walk you through manual entry of your carrier profile on the new device. Some carriers call this process "moving your eSIM," while others say they're "reactivating" or "provisioning" your service on the new phone.
Processing times vary. Some carriers can transfer an eSIM within minutes, while others may take a few hours. Inform the representative about any time-sensitive situations—if you need your service working by a specific time, let them know so they can prioritize your request appropriately.
Key takeaway: Contact your carrier by phone or in-person before attempting any technical steps. They'll verify your identity, deactivate your eSIM on the old phone, and provide instructions for setting it up on your new device.
Once your carrier has processed your eSIM transfer request, the actual setup on your new phone is relatively straightforward, though the exact steps depend on your phone type and whether you're staying with the same brand or switching.

For iPhone-to-iPhone transfers using the same Apple ID, the process can be particularly smooth. When you set up your new iPhone, you'll see an option during the setup process to transfer your eSIM from your old iPhone. You'll hold your old iPhone near your new iPhone, and they'll communicate wirelessly to transfer the eSIM profile. This uses a technology called UWB (ultra-wideband) on newer models or proximity detection on older ones. After the transfer, your old iPhone's eSIM becomes inactive, and your new iPhone takes over the service. You should see cellular service active within a few minutes.
If you're setting up an iPhone without your old phone nearby, you can still add the eSIM manually. Go to Settings, then Cellular, then Cellular Plans. Tap "Add Cellular Plan" and choose "Use QR Code" if your carrier provided one, or "Enter Details Manually" to input your carrier information. Your carrier representative will provide either the QR code or the manual entry details during your call with them.
For Android phones, the process is similar but accessed through different menus. Go to Settings, then look for "Network and Internet," "Mobile Networks," or "SIM and Network" depending on your manufacturer. You should see an option to add a new eSIM or cellular plan. You can scan a QR code provided by your carrier or enter the activation code manually. On Samsung phones specifically, this is often found under Settings > Connections > SIM Manager > Add Mobile Plan.
When switching between Android and iPhone, or between different Android manufacturers, the process is the same from a technical standpoint—you're just entering carrier information into a different
