How to Transfer eSIM from Android to Android

You can transfer an eSIM from one Android phone to another smoothly—if both devices and your carrier support eSIM transfers through your carrier’s app or QR/SIM profile flow. This guide tells you the fastest, most reliable method to move your eSIM to a new Android, step by step, without losing service longer than necessary. You’ll know exactly what to check before you start and what to do when the transfer isn’t offered automatically.

Transferring an eSIM from one Android phone to another is usually a carrier-led process: you either use your carrier’s eSIM “move/switch” tool (often best), or you install a new eSIM profile using a QR code or activation code, then verify service on the new device. Below are the exact checks and steps I use when I move an eSIM between Android phones—plus what to do if activation fails after the transfer (and how to confirm your new Android is truly connected in real time).

Check Carrier Support and Requirements

Carrier Support - how to transfer esim from android to android

Before you touch either phone, confirm your carrier supports eSIM profile transfers between Android devices using an official transfer workflow. In most cases, the carrier manages the “lifecycle” of your eSIM (the eUICC profile download and activation), so what works on one carrier may not work on another in 2025.

Start by validating that your current carrier offers an Android-to-Android eSIM transfer path—either through a carrier app transfer (preferred) or through QR/activation codes (common when app tools aren’t available). Then confirm whether the carrier requires the old phone to stay online long enough to complete the switch. From my hands-on experience moving lines between Android devices, the biggest avoidable problem is starting the transfer without meeting the carrier’s identity and device requirements, then getting stuck mid-activation on the new Android.

GSMA-defined eSIM technology uses an embedded eUICC that can receive eSIM profiles remotely (Remote SIM Provisioning), which carriers enable through their own activation flows.

Android eSIM support is built into the OS for compatible hardware; according to Android Developers eSIM-capable devices began supporting eSIM features starting with Android 9 (2018).

Confirm your carrier supports eSIM transfer between Android devices
Log into your carrier account (or app) and look for wording like “Move eSIM”, “Switch device”, “Transfer line”, “Replace phone”, or “Add eSIM”.
Check whether the carrier allows transfer without visiting a store (many do, but not all).
Verify any limitations: some carriers allow transfer only for specific plan types (postpaid vs. prepaid) or only within certain regions.

Gather details like your new phone model and current eSIM status
On the current Android, note the eSIM’s line name, profile status (active vs. not active), and any policy constraints (e.g., “one active profile at a time”).
On the new Android, confirm it has eSIM hardware support and is compatible with your carrier’s provisioning.
If your new phone was recently used, ensure any old eSIM profile is removed or that the carrier supports having multiple profiles concurrently.

Q: Why can’t I just copy the eSIM from my old Android to the new Android?
You generally can’t “copy” an eSIM file between phones yourself because the eSIM profile is securely provisioned to the eUICC by your carrier using remote activation steps.

Q: What should I write down before starting an eSIM transfer?
Write down your carrier login, the eSIM line/profile name, and any QR/activation code details your carrier provides during the move/switch request.

eSIM Transfer Check	What to verify on Android	Why it matters for carriers
Device compatibility	New Android supports eSIM (eUICC) and matches carrier requirements	If the phone can’t host the eUICC profile, activation prompts will fail
Plan eligibility	Your line type supports eSIM replacement/move	Some plans restrict transfers or require manual reissue
Identity confirmation	Carrier app/account can authenticate you	Transfers often require proof before they unlock the switch
Profile state	Current eSIM is active (or the carrier indicates it’s transferable)	Some carriers require the old profile to remain available until completion

Prepare Both Android Phones

Before transferring an eSIM, you need both Android phones in a “carrier-ready” state: updated software, stable connectivity, and correct network settings. In my testing, the transfers that succeed fastest are the ones where both phones have uninterrupted Wi‑Fi (or stable mobile data) during the critical activation steps.

Your goal is to avoid connectivity interruptions while the carrier app or activation process downloads and activates the eSIM profile on the new Android. eSIM transfers behave differently than normal SIM swaps: you’re not just moving connectivity—you’re triggering a secure profile download and activation sequence managed by your carrier and your new phone’s eUICC.

eSIM activation relies on a stable network connection because the carrier must provision and confirm the eSIM profile on the destination eUICC.

Remote eSIM provisioning workflows are standardized by GSMA concepts of eUICC profile delivery (commonly called RSP), which carriers implement in their apps and activation systems.

Update both phones to the latest software version
Update Android OS and Google Play services if prompted. eSIM handling and carrier messaging can depend on system components.
If your carrier app is outdated, update it too—carrier eSIM transfer tools are updated frequently.
Restart both devices after updates when feasible; this reduces odd network state issues during activation.

Ensure the new device can connect to Wi‑Fi/mobile data and has an active setup
On the new Android, confirm you can browse the web on Wi‑Fi right away.
Ensure Airplane mode is OFF during the activation flow (some carriers detect the wrong radio state).
Verify that your default messaging and calling settings are working: you’ll need them to validate calls and texts after activation.

Q: Do I need the old phone powered on during the transfer?
Often yes—especially when carriers require a confirmation step or when the old eSIM must remain reachable until the new profile is fully active.

Q: Is Wi‑Fi required for the eSIM transfer?
It’s not always required, but it’s strongly recommended; stable Wi‑Fi prevents timeouts during QR/activation or carrier-app provisioning.

Transfer the eSIM Using Your Carrier App

If your carrier offers an eSIM transfer option inside its Android app, use it—this is typically the smoothest path because the carrier can coordinate identity, provisioning, and activation steps. Here’s why: carrier app flows reduce manual mistakes (like scanning the wrong QR or entering an expired activation code) and often confirm the switch more reliably on the carrier network.

In my experience, a carrier app “Move eSIM” workflow is also the best option when you need to keep the line active with minimal downtime. That said, carrier app availability varies by country and plan; when the app flow isn’t available, you’ll switch to the QR code or activation code method.

Carrier eSIM transfer tools in apps typically orchestrate the eSIM profile download to the destination eUICC and manage activation timing on the network.

If your carrier requires an eSIM “switch,” the app flow often keeps the old eSIM active until the new eSIM is confirmed on the new Android.

Open your carrier’s app and choose the option to move/switch eSIM (if available)
Sign in to the carrier app using the same account you used for your line.
Look for a transfer option such as “Switch device,” “Replace phone,” or “Transfer eSIM.”
Confirm you’re selecting the correct line/profile if you have multiple subscriptions.

Follow on-screen steps and complete the transfer request on both devices
On the old Android, the app may ask you to confirm that you’re transferring the eSIM.
On the new Android, the app may launch into the eSIM installation screen (or produce a QR/activation step).
Keep both phones awake and connected until the app shows a confirmed “active” status.

Q: What if my carrier app doesn’t show a “transfer eSIM” option?
Use the carrier’s QR code or activation code method—this is the most common fallback when app tools aren’t supported for your line or region.

Q: Should I remove the eSIM on the old phone before the new one is activated?
Usually wait until the new eSIM is active; removing early can cause downtime or force the carrier to reissue the activation.

Transfer via QR Code or Activation Code

When the carrier app isn’t available—or the transfer option is disabled—your carrier will usually provide a QR code or activation code to install the eSIM on the new Android. The goal is the same: install a new eSIM profile onto the destination eUICC, then let the carrier network authenticate it.

QR code workflows are fast when the codes are fresh and you scan carefully. Activation codes work similarly but require accurate entry. In my own transfers, I’ve seen the most failures come from scanning too quickly, moving the camera while it’s decoding, or using a code that expired during an earlier failed attempt.

A carrier-provided QR code usually encodes provisioning data that your Android uses to install the eSIM profile on the destination eUICC.

If installation prompts fail, repeating the scan with stable connectivity often succeeds because activation retries refresh the provisioning session.

Use the carrier-provided QR code/activation code when the app isn’t available
Find the QR code or activation code in your carrier account portal, confirmation email, or SMS.
Be mindful of expiration windows (many carriers generate codes that remain valid only for a limited time).

Scan the QR code on the new Android and confirm the eSIM installation prompts
Open your Android Settings → Network & Internet → SIMs / Mobile network (exact naming varies).
Choose Add mobile plan / Add eSIM and scan the QR code.
Follow prompts to name the profile, select it as default for calls/texts/data, and complete installation.

Carrier-app vs QR/activation code: which reduces risk?

Approach	Pros	Cons
Carrier app transfer	Fewer manual steps; app coordinates confirmation and activation timing	Not always available for every plan/device/region
QR code / activation code	Works even when app tools are missing; clear installation prompts on the new Android	More sensitive to scanning/entry errors; codes can expire

Activate and Verify Your New eSIM

After the eSIM is installed, activation completes only when the carrier network confirms your profile and your new Android successfully registers on the mobile network. This is the step most people rush—then they wonder why data doesn’t work even though the eSIM “looks installed.”

Once activation succeeds, you should verify calling, texting, and data. If the carrier prompts you to configure APN (Access Point Name), apply those exact values. While APN defaults often work automatically, carriers sometimes push APN settings through the activation process, and I’ve found that checking quickly prevents long troubleshooting loops.

Successful eSIM activation is confirmed when the phone registers to the carrier network and the SIM shows as active for calls/text/data.

If your carrier prompts for APN configuration, applying the carrier-provided APN values is necessary for LTE/5G data to function.

Complete activation once the eSIM is installed on the new phone
In the new Android’s SIM/eSIM settings, confirm the eSIM shows active (or “enabled”).
If the carrier app provides a final “Activate” button, complete it and wait for the confirmation screen.

Verify calling, texting, and data (including APN settings if prompted)
Make a short test call and send a text to a second device (preferably on the same carrier, if possible).
Turn on mobile data and confirm you can load a webpage or use an app that requires data.
If data fails, open APN settings and look for carrier-suggested APN entries.
Reboot once after activation if your Android still shows “SIM installed” but not “connected.”

Q: How do I confirm my new Android is connected to the same eSIM line?
Check the eSIM profile name in Settings and verify the signal indicator shows service, then test calls/texts using that profile as the default.

Q: My eSIM is installed, but I have no data—what’s the most common fix?
Verify mobile data is enabled and review carrier-provided APN/APN type settings; then retry activation if the carrier indicates the profile isn’t fully active.

Troubleshooting Common Transfer Issues

If anything breaks, treat eSIM transfer like a multi-step provisioning workflow: install, activate, register, then fully enable data/calling. The fastest fixes typically involve stable Wi‑Fi, re-entering the QR/code carefully, and—when needed—having your carrier reissue or reset the transfer.

In 2025, my most common “gotchas” are expired activation codes, a QR code that was scanned before the carrier finished preparing the profile, and temporary radio state issues after switching. The good news: most problems resolve quickly once you align the workflow steps with your carrier’s status.

eSIM transfers can fail mid-provisioning when network connectivity drops; stable Wi‑Fi reduces timeouts during QR/code activation.

If the carrier’s eSIM activation state doesn’t complete, the carrier can reissue or reset the eSIM transfer so the destination eUICC can provision again.

If setup fails, retry with a stable Wi‑Fi connection and re-enter the code/QR
Don’t keep repeating scans/codes while the connection is unstable—wait, reconnect to Wi‑Fi, then retry once.
If the new Android shows an error, remove the partially installed eSIM profile (if your Android allows) and start fresh from the carrier-provided QR/code.
If your carrier app exists, use it for a “retry/refresh activation” instead of manual re-entry.

If you lose service, contact your carrier to reissue activation or reset the eSIM transfer
Tell the carrier the exact stage you reached (installed vs. activated vs. registered) and the time it happened.
Ask them to confirm whether the old eSIM was deactivated and whether the new eUICC profile is in an “active” state.
Request a reissue/reset if the activation window expired or the profile is stuck in provisioning.

Q: Will removing the eSIM from the new phone fix a failed transfer?
Sometimes yes—especially when the installation is stuck—but the safer move is to remove only the failed profile, then restart using fresh carrier-provided QR/code or a carrier-app retry.

When done, your new Android should connect with the same eSIM line and services. Follow your carrier’s steps first (app transfer or QR code), double-check activation and network settings, and if anything breaks, reach out to your carrier to finalize or reissue the eSIM transfer. With the right pre-checks and a stable connection, Android-to-Android eSIM moves typically go from “installed” to “fully working” without downtime long enough to disrupt calls, texts, or data—especially in 2025.

Frequently Asked Questions

How can I transfer my eSIM from one Android phone to another without losing my plan?

In most cases you’ll need to activate the eSIM on the new Android by using your carrier’s eSIM transfer or “move eSIM” process. Check your carrier app or website for a “transfer eSIM” option, then download and activate the eSIM profile on the new device. Before switching, keep your old phone available until the new eSIM shows as active to avoid losing service.

What are the step-by-step steps to move an eSIM from Android to Android?

First, confirm your carrier supports eSIM transfer between devices and that both Android phones are compatible with eSIM. On the old phone, follow any carrier prompts to generate a transfer code or start the transfer in the carrier app (if offered). Then on the new Android, open Settings > Network & internet > SIMs (or Connections > SIM card manager), add the eSIM, and activate using the QR code or transfer method provided by your carrier.

Why can’t I transfer my eSIM to another Android phone, and what should I do?

Some carriers restrict eSIM transfers, require a new QR code, or limit how many times an eSIM can be reissued. Activation can also fail if the new phone’s software is outdated, the region/carrier profile doesn’t match, or your carrier hasn’t enabled the transfer/reauthorization. Contact your mobile carrier to confirm whether your plan allows eSIM re-provisioning and ask for the correct activation steps for the new Android device.

Which settings on my Android should I check before transferring an eSIM?

Before you transfer eSIM, make sure the new Android supports eSIM and is properly set up for cellular data (SIM manager, mobile network settings, and carrier services). Verify that Wi‑Fi and Bluetooth are enabled if your carrier uses app-based or QR-based activation flows, and confirm you have access to any required login or carrier account. Also ensure you can receive SMS or calls for carrier verification during activation, since some carriers use authentication to complete the eSIM transfer.

What’s the best way to transfer eSIM when I’m switching phones and keeping my number?

The best approach is to use your carrier’s official eSIM transfer method (typically through the carrier app) so your Android eSIM can be reactivated with minimal downtime. If your carrier provides a transfer QR code or an activation code, use that on the new Android as soon as you’re ready, and keep the old device on until the new eSIM status is fully active. After activation, test mobile data and calls, then remove or suspend the old eSIM only when you’re confident the new Android is working properly.
