How to Set Up eSIM on Your Android Phone (2026 Guide)

An eSIM lets you activate a mobile plan on your Android phone without inserting a physical SIM card. The SIM information is downloaded digitally to a small chip already built into your phone, so you can add a new number, switch carriers, or use a local plan while travelling — often in just a few minutes, and without hunting for a SIM ejector tool. If your phone supports it, setting up an eSIM is one of the simplest upgrades you can make. This guide explains what an eSIM is, how to check whether your phone supports it, how to get one from your carrier, and how to activate and manage it on Samsung, Pixel, and other Android phones, including dual SIM use, travel, transfers to a new phone, and the most common problems.

What Is an eSIM, and How Is It Different from a Physical SIM?

eSIM stands for embedded SIM. Instead of a small plastic card that you slide into a tray, an eSIM is a rewritable chip soldered inside the phone. When you buy a mobile plan, your carrier sends you the plan details — usually as a QR code, an activation code, or through the carrier's own app — and your phone downloads that profile onto the chip. Once activated, the eSIM works just like a normal SIM: it connects to the mobile network, handles calls, texts, and mobile data, and identifies you to your carrier.

The practical differences matter most in everyday use. With a physical SIM, changing numbers or carriers means swapping a tiny card, and losing that card can be a real headache. With an eSIM, you can add a plan by scanning a code, keep several eSIM profiles stored on one phone (though usually only one or two can be active at a time — check with your carrier and phone maker), and switch between them from Settings without touching any hardware. That makes eSIM especially useful for two situations: keeping a work number and a personal number on one phone, and adding a local or travel plan abroad while keeping your home number active for calls and messages.

There are a few limits to keep in mind. Not every Android phone supports eSIM, and not every carrier offers it, so compatibility is the first thing to check. Some carriers also restrict how many times an eSIM can be transferred, and an eSIM profile is tied to the phone it was activated on until you move it properly. None of this makes eSIM complicated, but it does mean you should follow the steps in order rather than guessing — especially before you delete an old profile or wipe a phone.

Step 1: Check That Your Phone and Carrier Support eSIM

Before you order an eSIM, confirm two things: your phone has eSIM hardware, and your carrier supports eSIM for your plan. Either one missing means activation will fail, so spend two minutes here and save yourself a failed setup later.

Check on your phone

1. Open Settings and use the search bar at the top. Type eSIM or SIM manager.
2. If you see an option such as Add eSIM, SIM manager, or Mobile network → Add eSIM, your phone supports eSIM. On Samsung phones, look under Settings → Connections → SIM manager. On Pixel phones, look under Settings → Network & internet → SIMs.
3. On other Android phones, the path varies slightly, but the Settings search is the fastest route: searching for "eSIM" will surface the right screen if the feature exists.
4. If nothing appears, check your phone maker's official specifications for your exact model. Some phones sold in certain regions have eSIM disabled, even when the same model supports it elsewhere, so the model name alone is not always enough.

Check with your carrier

• Ask your carrier whether eSIM is available on your current plan, or whether you need to switch plans. Some carriers offer eSIM only on certain plans or for postpaid customers.
• Ask whether there is a fee for converting a physical SIM to eSIM, and whether your number stays exactly the same. In most cases it does, but confirm before you start.
• Check whether your carrier is unlocked for eSIM use. If your phone is locked to one carrier, an eSIM from another carrier may not activate until the phone is unlocked — check with your carrier if you are unsure.
• Make sure your phone is updated and connected to WiFi before activation. Updates and downloads go far more smoothly on a stable WiFi connection than on mobile data.

Step 2: Get Your eSIM from Your Carrier

Once compatibility is confirmed, your carrier will give you the eSIM in one of three ways. The method depends on the carrier, so use whichever one they provide — the end result is the same.

• QR code: the most common method. Your carrier emails you a QR code, prints it in a store, or shows it in your online account. You scan it with your phone's camera during setup, and the phone downloads the eSIM profile.
• Activation code: a set of details you type in manually — usually an address and an activation code. Use this if your camera cannot scan the QR code, or if your carrier does not issue one.
• Carrier app: some carriers activate eSIM directly inside their own app. You sign in, choose the eSIM option, and the app installs the profile for you without a QR code.

Keep the QR code or activation details somewhere safe until activation is fully finished and tested — do not delete the email or throw away the printout early. If activation fails halfway, you will need those same details again, and some carriers only allow a code to be used a limited number of times. If you are converting your existing number from a physical SIM to eSIM, your old physical SIM usually stops working once the eSIM activates. That is normal, but it is another reason not to remove or discard anything until the new eSIM is confirmed working with a test call or a mobile data check.

Step 3: Activate Your eSIM Step by Step

The overall flow is the same on every Android phone: open the SIM settings, choose to add an eSIM, scan the QR code or enter the activation code, wait for the download, and confirm. Menu names differ by brand, so follow the section that matches your phone.

On Samsung phones

1. Connect to WiFi, then open Settings → Connections → SIM manager.
2. Tap Add eSIM.
3. Tap Scan QR code and point your camera at the carrier's QR code. If you have an activation code instead, tap Enter activation code and type in the details exactly as given.
4. Wait while the phone downloads the eSIM profile. Do not close Settings or turn off WiFi during this step.
5. When prompted, turn on the new eSIM and choose whether it should handle calls, texts, and mobile data, or only one of those. You can change this later.
6. Restart your phone if the network does not appear right away, then check the signal icon and try a test call or a quick mobile data check.

On Pixel phones

1. Connect to WiFi, then open Settings → Network & internet → SIMs.
2. Tap Add SIM or Add eSIM (the exact label varies by Android version).
3. Tap Set up an eSIM or Use a QR code, then scan the carrier's QR code. For manual entry, choose the option to enter details manually and type in the activation code.
4. Wait for the download to finish, then follow the prompts to turn on the eSIM and pick your preferences for calls, texts, and data.
5. Restart the phone if needed, then confirm the new network name appears and mobile data works.

On other Android phones

1. Open Settings and search for eSIM or Add SIM.
2. Open the SIM or mobile network screen that appears and choose Add eSIM.
3. Scan the QR code or enter the activation code, wait for the download, and follow the on-screen prompts to enable the profile.
4. If your phone maker has its own guide, follow that for any brand-specific step — the core flow is the same, but button labels can differ.

Using Dual SIM: Physical SIM Plus eSIM Together

One of the best reasons to use eSIM is dual SIM: you can keep your physical SIM active and add an eSIM as a second line, or use two eSIM profiles where your phone allows it. Each line keeps its own number, and you choose which one handles calls, texts, and data.

Common dual SIM setups include a personal number plus a work number on one phone, a home number plus a travel plan abroad, and a main data line plus a cheaper backup line. Your phone will usually label each line — for example SIM 1 and SIM 2, or by the carrier name — and you can give each line a name or colour in some SIM managers to avoid confusion. When someone calls you, the phone shows which line the call is coming in on, and when you make a call, you can usually pick the line from the dialler or set a default.

Be aware of one practical detail: on many Android phones, only one line can use mobile data at a time, and switching data between lines takes a few seconds while the phone reconnects. That is normal. Also, if you set one line for calls and another for data, make sure you know which is which — an accidental data switch to a roaming line abroad can be expensive, so check with your carrier about roaming charges before you travel.

Switching Your Data and Default Lines

Your default lines control which SIM is used automatically. You can change them at any time from Settings, without reactivating anything.

1. Open Settings and go to your SIM manager (Connections → SIM manager on Samsung, Network & internet → SIMs on Pixel).
2. Under Preferred SIM or Default SIM, choose a line for Calls, a line for Texts, and a line for Mobile data. These can be three different choices, or all the same line.
3. To switch data to the other line, change only the mobile data setting — calls and texts stay where they were.
4. To make calls from the other line just once, many diallers let you pick the line for that single call without changing the default. Look for the SIM icon in the dialler before you press call.
5. To temporarily turn a line off — for example, to stop a travel line draining battery after a trip — toggle that eSIM off in the SIM manager instead of deleting it. Toggling off keeps the profile stored so you can turn it back on later, while deleting removes it permanently.

If you are unsure which line is active, the quickest check is the signal bar and the SIM manager itself: it shows which lines are on, which is set for data, and which networks they are connected to. Change one setting at a time and test after each change, so you always know what caused a difference.

Travelling with a Travel eSIM

Travel eSIMs are one of the most popular uses of the technology. Instead of buying a physical SIM at the airport or paying your home carrier's roaming rates — check with your carrier what those rates are before you travel — you buy a data plan for your destination from your home carrier or a travel eSIM provider, install it before you leave, and switch your mobile data to it when you land.

The setup is straightforward: install the travel eSIM while you are still on WiFi at home, keep it toggled off or set your home line as the data line until you arrive, then switch mobile data to the travel eSIM after landing and turn on data roaming for that line only if the provider requires it. Your home number stays active for incoming calls and texts on the other line, so you do not miss anything important. Just be careful with one setting: make sure mobile data is set to the travel line, not your home line, before you start browsing, or you could accidentally use expensive roaming data.

When the trip ends, toggle the travel eSIM off or delete it if you will not use it again. Keep it if you visit the same destination often and the plan is still valid — check the provider's terms for expiry. And remember that a travel eSIM is usually data-only: it may not include a phone number for regular calls, so check what the plan covers before you rely on it for calls or texts.

Transferring Your eSIM to a New Phone

Moving an eSIM to a new phone is not quite like moving a physical SIM card, because the profile lives on the old phone's chip. The safe way to do it depends on your carrier, so check their transfer process before you wipe or sell the old phone.

• Ask your carrier first. Many carriers let you transfer an eSIM through their app, website, or a new QR code. Some require you to request a fresh eSIM for the new phone, and the old profile stops working once the new one activates.
• Use the phone's transfer tools where offered. Newer Android versions and manufacturer tools can move some eSIM profiles during device setup. Follow the on-screen prompts during setup if your new phone offers this — it is easier than starting from scratch.
• Do not delete the old profile until the new phone works. Keep the old phone charged and untouched until you have made a test call and checked mobile data on the new phone. Deleting early is the most common way people lock themselves out of a number mid-transfer.
• Back up everything else first. An eSIM transfer moves only the mobile plan, not your photos, chats, or apps. If you are switching phones, our guide on backing up your Android phone walks through the full backup before you wipe the old device.

If you are selling or giving away the old phone, delete the eSIM profile from it only after the new phone is fully working and after a factory reset is planned. A factory reset normally removes eSIM profiles, but confirm this in your phone's reset screen — some phones ask whether to keep or erase eSIMs during reset, and you should choose to erase them when handing the phone to someone else.

Troubleshooting Common eSIM Problems

The QR code will not scan

Clean your camera lens, hold the phone steady about 20 centimetres from the code, and make sure the code is well lit and not creased or glared. If scanning still fails, use the manual activation code option instead and type the details carefully — a single wrong character will block activation. If your carrier gave you the code on paper, double-check for characters that look alike, such as the letter O and the number 0.

"No service" after activation

First, check that the eSIM is toggled on in the SIM manager and set as the line for the service you are testing. Then restart the phone, check that you are in an area with coverage, and confirm mobile data or roaming is enabled if your plan needs it. If the problem persists, remove and re-add the profile only if your carrier allows reuse of the code — otherwise, contact your carrier before deleting anything, since a deleted profile sometimes cannot be re-added with the same code.

Activation is stuck on downloading

Stay on strong WiFi and wait a few minutes — downloads can pause on weak connections. If it stays stuck, restart the phone and try again from the SIM manager. Do not factory reset the phone to fix a stuck download; that rarely helps and can complicate the transfer. If the download fails repeatedly, your carrier may need to issue a fresh QR code or activation code.

The wrong line is being used for data or calls

This is almost always a default-line setting, not a fault. Open the SIM manager and check which line is set for mobile data, calls, and texts, then change the one that is wrong. Test after each change with WiFi off for data, or a short call for voice.

When to contact your carrier

Contact your carrier if activation fails more than once, if your number does not transfer correctly, if the eSIM option is missing despite your phone supposedly supporting it, or if you need a fresh code after deleting a profile. Have your account details, phone model, and any error message ready — that information lets support help you far faster than a vague "it doesn't work" report.

eSIM Security Tips

• Never share screenshots of your eSIM QR code. Anyone with that code could potentially activate your number on their own device. Treat a QR code like a password: keep it private, and delete screenshots once activation is confirmed.
• Delete old eSIM profiles you no longer use. Old travel or work profiles left on a phone are clutter at best and a confusion risk at worst. Remove them once a trip or job ends, after confirming you no longer need the number.
• Lock your phone and your carrier account. A strong screen lock, and a PIN or password on your carrier account where offered, make it much harder for someone else to transfer your number. If your carrier offers a transfer lock or number porting protection, turn it on.
• Be careful on public WiFi during setup. Activate your eSIM on a trusted WiFi network or mobile data where possible, and avoid entering carrier account details on shared or unsecured networks.
• Erase eSIMs before selling a phone. Delete all eSIM profiles and factory reset the device before handing it over, as described in the transfer section above.

Frequently Asked Questions

Can I use an eSIM and a physical SIM at the same time?

Yes, on most eSIM-capable Android phones. That is the standard dual SIM setup: one physical SIM plus one eSIM, each with its own number, and you choose which handles calls, texts, and data.

Does eSIM work without internet?

Once activated, an eSIM works like any SIM and does not need WiFi for calls, texts, or mobile data. You do need an internet connection — usually WiFi — for the initial download of the eSIM profile.

Can I delete an eSIM and get it back later?

Deleting an eSIM removes the profile from your phone. Whether you can re-add it depends on your carrier: some let you reuse the same QR code, others require a new one. Check with your carrier before deleting a profile you might need again.

Is eSIM safe?

Yes, when handled sensibly. The profile is stored on a secure chip in your phone, and there is no physical card to lose or steal. The main risks are human ones — sharing your QR code, or leaving old profiles on a phone you sell — and both are easy to avoid with the tips above.

Do I need to keep my physical SIM after switching to eSIM?

Once your eSIM is activated and tested, the physical SIM for the same number is normally deactivated by the carrier, so keeping it does not keep the number alive on two devices. You can safely discard it, but only after the eSIM is confirmed working.

Setting up an eSIM on Android takes only a few minutes once you know the steps: confirm your phone and carrier support it, get your QR code or activation code, scan or enter it in the SIM manager, and choose your default lines. From there, dual SIM use and travel plans become far simpler — no more swapping tiny cards, no more airport SIM queues. Take your time with the compatibility check, keep your QR code private, and do not delete an old profile until its replacement is tested and working. Do that, and your eSIM will simply work quietly in the background, exactly as a SIM should.
