How to Set Up an eSIM on Android

    October 2, 2026 guide4you No Comments

    An eSIM is a digital SIM card built into your phone — no tiny plastic chip, no ejector tool, no store visit. You can buy a mobile plan online, scan a QR code, and be connected in minutes. It’s the easiest way to add a second number, switch carriers, or get affordable data when traveling abroad.

    This guide walks you through the whole process on Android: checking that your phone supports eSIM, getting an eSIM plan, installing it step by step on Pixel, Samsung, and other phones, and managing dual-SIM settings afterward.

    What Is an eSIM?

    eSIM stands for embedded SIM. Instead of a removable plastic card, the SIM circuitry is soldered into your phone at the factory. A “SIM profile” — your carrier plan — is downloaded onto that chip as software.

    What this means in practice:

    • No physical card to lose or swap. Your plan arrives as a QR code or activation code, usually by email.
    • Multiple profiles on one phone. You can store several eSIM profiles (typically 5–8 depending on the phone) and switch between them in Settings. Only one or two can be active at a time, depending on the model.
    • True dual SIM. Most eSIM Android phones can run a physical SIM and an eSIM simultaneously — perfect for keeping your home number while using a local data plan abroad.
    • Instant carrier switching. Buy a plan online, scan, done — no waiting for a SIM to ship.

    What You’ll Need

    1. An eSIM-compatible Android phone. Most flagships from the last several years qualify: Google Pixel 3 and newer, Samsung Galaxy S20 and newer, Galaxy Z Fold/Flip series, and many Motorola, Xiaomi, and Oppo models. Carrier-locked phones must be unlocked first.
    2. An eSIM plan from a carrier or provider. This can be your regular mobile carrier or a travel eSIM provider (Airalo, Holafly, Nomad, and similar) if you want data abroad.
    3. The QR code or activation details from that provider — usually delivered by email or shown in the provider’s app.
    4. A stable Wi-Fi connection. The eSIM profile downloads over the internet, so you need Wi-Fi (or existing mobile data) during setup.
    5. About 10 minutes.

    Part 1: Check That Your Phone Supports eSIM

    Do this before buying any plan — it takes 30 seconds.

    Method A: Dial the EID check

    1. Open your Phone dialer app.
    2. Dial *#06#.
    3. Your IMEI number(s) appear. If you also see an EID (Embedded Identity Document) number — a long string of digits — your phone has eSIM hardware.

    No EID listed? Your phone doesn’t support eSIM.

    Method B: Look for the “Add eSIM” option

    • Pixel: Settings > Network & internet > SIMs — if you see an Add SIM / Add eSIM option, you’re good.
    • Samsung: Settings > Connections > SIM manager — look for Add eSIM or Add mobile plan.
    • Other Android: Settings > Network & internet > Mobile network — look for Add carrier or Download a SIM.

    Method C: Check the manufacturer’s compatibility list

    Even with eSIM hardware, some carriers or regions restrict eSIM activation. Google, Samsung, and Motorola all publish eSIM-compatible model lists — and your carrier can confirm whether your specific model is whitelisted on their network. If you’re buying a travel eSIM, the provider’s site usually has a compatibility checker where you enter your model.

    Important: a carrier-locked phone generally can’t install another carrier’s eSIM until it’s unlocked. Check with your carrier about unlocking before you travel.

    Part 2: Get Your eSIM Plan

    You have two main routes:

    Option A: From your mobile carrier

    Contact your carrier (in store, by phone, or through their app) and ask to convert your physical SIM to eSIM or add a new eSIM line. They’ll issue a QR code or push the profile to your phone. Some carriers support instant in-app conversion — for example, converting without ever handling a QR code.

    Option B: From a travel eSIM provider

    If you want data for a trip abroad, travel eSIM providers sell country or regional data plans entirely online:

    1. Pick your destination and data amount on the provider’s website or app.
    2. Pay online — you’ll typically receive a QR code by email immediately, plus manual activation details (SM-DP+ address and activation code) as a backup.
    3. Don’t install it until you need it — or do install it early but only enable data roaming on arrival. Check the plan terms: some plans start their validity countdown at purchase, others at first connection or installation. Installing early is usually safe; activating early sometimes isn’t. When in doubt, install at home on Wi-Fi and toggle it on when you land.

    Keep the QR code accessible on a second screen (laptop, tablet, or another phone) or as a printout — you can’t scan a code displayed on the same phone you’re setting up.

    Part 3: Install the eSIM — Step by Step

    The exact menu names differ slightly by brand, but the flow is the same everywhere: open the SIM settings, choose to add/download an eSIM, scan the QR code, confirm, wait for the download.

    On Google Pixel

    1. Connect to Wi-Fi.
    2. Open Settings.
    3. Tap Network & internet.
    4. Tap SIMs.
    5. Tap Add SIM (or the + icon, depending on your Android version).
    6. Choose Download a SIM instead? (wording varies: “Download a new eSIM” on newer versions).
    7. Tap Next. Your camera opens as a QR scanner.
    8. Point the camera at your provider’s QR code. Hold steady until the phone recognizes it — the plan details appear on screen.
    9. Tap Download / Add to confirm. The profile downloads — this takes 30 seconds to a few minutes on good Wi-Fi. Don’t close Settings or turn off Wi-Fi mid-download.
    10. When it finishes, you’ll see the new eSIM listed under SIMs. Tap it to rename it (e.g., “Thailand Travel” or “Work”) and configure it (next part).

    Can’t scan the code? On the QR scanner screen, tap Need help? or Enter it manually (wording varies) and type the SM-DP+ address and activation code from your provider’s email, plus the confirmation code if one was supplied. Then tap Continue.

    On Samsung Galaxy

    1. Connect to Wi-Fi.
    2. Open Settings.
    3. Tap Connections.
    4. Tap SIM manager (on older One UI versions: SIM card manager).
    5. Under the eSIMs section, tap Add eSIM (or Add mobile plan).
    6. Tap Scan QR code from service provider (wording varies slightly by One UI version).
    7. Scan the QR code with your camera.
    8. Tap Add / Register when the plan details appear, and wait for the download to complete.
    9. Back in SIM manager, tap the new eSIM to turn it on, rename it (tap the name or the edit icon), and assign it an icon/color so you can tell your SIMs apart at a glance.

    Manual entry on Samsung: on the scan screen, tap Enter activation code and type the details from your provider.

    On Motorola, Xiaomi, Oppo, OnePlus, and others

    1. Connect to Wi-Fi.
    2. Open Settings.
    3. Tap Network & internet (Xiaomi/HyperOS: SIM cards & mobile networks; OnePlus/OxygenOS: Mobile network or SIM & network).
    4. Look for Add eSIM, Download SIM, or Add carrier — sometimes under Mobile network > Advanced > Carrier.
    5. Scan the QR code or enter the activation details manually.
    6. Confirm and wait for the download.

    If you can’t find the option, use the search bar at the top of Settings and type “eSIM” — Android will jump you straight to the right screen.

    Part 4: Configure Dual SIM Settings

    Once the eSIM is installed, tell your phone how to use it — especially if you also have a physical SIM.

    Choose which SIM does what

    • Pixel: Settings > Network & internet > SIMs — tap each SIM to toggle it on/off. Tap Calls & SMS and Mobile data preferences to assign roles: for example, calls/SMS on your physical home SIM, mobile data on the travel eSIM.
    • Samsung: Settings > Connections > SIM manager — under Preferred SIMs (or Primary SIM), set Calls, Texts, and Mobile data individually. A classic travel setup: calls/texts on your home SIM, mobile data on the eSIM.

    Enable data roaming on the travel eSIM

    Travel eSIMs almost always require data roaming to be on — this is normal and expected (you’re roaming onto partner networks; the eSIM plan covers the cost, not your home carrier):

    • Pixel: Settings > Network & internet > SIMs > [your eSIM] > toggle Roaming on.
    • Samsung: Settings > Connections > Mobile networks > toggle Data roaming on (applies per-SIM; make sure the eSIM is the data SIM first).

    Critical: make sure data roaming is off for your home physical SIM if you don’t have a roaming plan with your home carrier — otherwise background data could route through the expensive home line. The safest travel setup: home SIM set for calls/SMS only (roaming off), eSIM set for mobile data (roaming on).

    Rename and label your SIMs

    Give each SIM a clear name (“Home – AIS”, “Japan Travel eSIM”) and, on Samsung, a distinct color. When you’re juggling two lines, clear labels prevent expensive mistakes — like accidentally calling from the wrong number.

    Set the eSIM as default for data before you fly

    If your plan’s validity starts on first use, you can safely install at home and leave the eSIM toggled off until landing. On arrival: turn off airplane mode, toggle the eSIM on, confirm it’s selected for mobile data with roaming enabled, and wait a minute or two for it to register on a local network.

    Part 5: Managing eSIMs Day to Day

    • Switching between profiles: just toggle SIMs on/off in the SIM settings — no reboot needed in most cases. Your phone can store many profiles but typically only two can be active at once.
    • Temporarily disabling: toggle the eSIM off when you don’t need it (e.g., back home after a trip) rather than deleting it — the profile stays stored and can be reactivated later if the plan is still valid.
    • Deleting a profile: in the SIM settings, tap the eSIM and choose Erase / Delete. Only do this when you’re sure the plan is finished — deleted profiles usually cannot be reinstalled from the same QR code. If you think you might need it again, disable it instead.
    • Transferring to a new phone: eSIMs don’t move automatically. On Pixels, the setup wizard offers an eSIM transfer from your old Pixel via Bluetooth/Wi-Fi during initial setup (works best for carrier eSIMs). Otherwise, ask your provider for a new QR code — most carriers and travel providers reissue them free or cheaply. Never delete the old profile until the new phone is working.

    Troubleshooting

    “Couldn’t add eSIM” / download fails

    1. Check Wi-Fi. The download needs a stable connection — weak hotel Wi-Fi is the #1 cause. Move closer to the router or try another network.
    2. QR code already used? Most eSIM QR codes are single-use. If you scanned it before (even partially), request a fresh code from your provider.
    3. Phone locked to a carrier? A carrier-locked phone rejects other carriers’ eSIMs. Confirm unlock status with your carrier.
    4. Restart and retry. A surprising number of eSIM failures clear with a reboot.
    5. Try manual entry. If the camera won’t read the code, type the SM-DP+ address and activation code by hand — typos are common, so go slowly.

    eSIM installed but “No service”

    • Toggle the eSIM off and on in SIM settings.
    • Toggle airplane mode on for 10 seconds, then off — this forces a fresh network registration.
    • Confirm data roaming is on for the eSIM (travel plans need it).
    • Check the eSIM is actually selected as the mobile data SIM.
    • Try manually selecting a network: Settings > Network & internet > SIMs > [eSIM] > turn off Automatically select network and pick a carrier from the list. Your provider’s instructions often name the correct partner networks per country.
    • Verify the plan is active and has data remaining in the provider’s app.

    Can’t receive calls/texts on the eSIM number

    Many travel eSIMs are data-only — they have no phone number at all, by design. If you bought a plan expecting a number, check the plan details: data-only is the norm for travel eSIMs. Your home physical SIM still handles calls and SMS (keep it active for those, with roaming off to avoid data charges).

    Battery drain after adding eSIM

    Running two active SIMs uses slightly more power — the phone maintains two network registrations. If battery life matters more than dual standby, toggle off the SIM you’re not using.

    “This eSIM can’t be added because the EID is already in use”

    This rare error means the profile is tied to another device’s EID. Contact your provider for a fresh QR code issued for the new phone.

    Frequently Asked Questions

    Is eSIM better than a physical SIM?

    For flexibility, yes: instant activation, multiple stored profiles, no lost cards, and easy dual-SIM. For simplicity, a physical SIM is still fine — and it’s easier to move between phones by just swapping the card. Neither is inherently “better” for call quality or speed; that’s all about the carrier network.

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

    Yes — that’s the most popular setup. Keep your home number on the physical SIM for calls and texts, and run mobile data on the eSIM. Both stay active simultaneously on virtually all eSIM-capable Android phones.

    Does eSIM work for international roaming?

    That’s its best use case. Buy a local or regional travel eSIM before your trip, install it on Wi-Fi at home, and land with data ready — usually far cheaper than your home carrier’s roaming rates.

    Can I convert my current physical SIM to eSIM?

    Most major carriers allow it — usually through their app, customer service, or in store. The process deactivates the physical SIM and issues an eSIM profile. Keep the physical SIM until the eSIM is confirmed working.

    What happens to my eSIM if I factory reset my phone?

    A factory reset normally erases eSIM profiles along with everything else (some phones offer a “keep eSIMs” checkbox during reset — look for it). Before resetting, check whether your provider can reissue the QR code, or you’ll be without service until they do.

    Are eSIM QR codes safe to screenshot or forward?

    Treat a QR code like a SIM card: anyone who scans it first can claim the plan. Don’t post it publicly or forward it casually. Once installed on your phone, the original code is spent (single-use) and harmless.

    Conclusion

    Setting up an eSIM on Android is genuinely a ten-minute job once you know where the menus live: confirm your phone has an EID, get a plan and its QR code, then Settings > Network & internet > SIMs > Add SIM (Pixel) or Settings > Connections > SIM manager > Add eSIM (Samsung), scan, and configure your dual-SIM roles. Do the install on solid Wi-Fi before you travel, keep data roaming straight (on for the travel eSIM, off for home), and you’ll land connected while everyone else is hunting for a SIM kiosk. Welcome to the no-plastic future.
