How to Install eSIM Android (2026): Step-by-Step Guide
TL;DR
Installing an eSIM on Android means downloading a digital carrier profile to your phone, either by scanning a QR code or entering an SM-DP+ address manually. The exact menu path differs by brand: Samsung uses Settings > Connections > SIM Manager, Pixel uses Settings > Network & Internet > SIMs, and Xiaomi uses Settings > SIM cards & mobile networks. Before you start, confirm your phone has an EID and is carrier-unlocked. Most problems after install come down to three things: data roaming is off, the wrong SIM is selected for data, or the APN didn’t auto-configure.
An eSIM is a SIM card built directly into your phone’s motherboard. There’s no plastic tray, no tiny chip to fumble with. Instead, you download a carrier profile over Wi-Fi, and your phone connects to the network just like it would with a traditional SIM. According to the GSMA, roughly 76% of all smartphone connections globally will be eSIM-based by 2030, reaching about 6.7 billion devices.
The process of installing an eSIM on Android should take under five minutes. But Android fragmentation makes it confusing: Samsung, Pixel, and Xiaomi all use different menu names for the same thing. This guide consolidates the terminology, walks through each device’s exact path, and covers the fixes that practitioners report needing most often.

What “Install eSIM” Actually Means on Android
Two terms get conflated constantly, and the confusion causes real problems for travelers.
Install means downloading the eSIM profile onto your phone. The profile sits there, ready but inactive. Activate means turning that profile on so it connects to a cellular network. For travel eSIMs, this distinction matters enormously: many plans only start their data countdown when you first connect to a local network abroad, not when you scan the QR code. So you can install at home on your couch and activate days later when you land.
There are two ways to install an eSIM on any Android phone:
- QR code scan — Your eSIM provider emails you a QR code. You scan it from your phone’s network settings, and the phone downloads the profile automatically.
- Manual SM-DP+ entry — You type in a server address and activation code by hand. Same result, different input method.
Both methods are equally reliable. The manual method isn’t a fallback; it’s the primary option when you’re viewing the QR code on the same phone you need to install it on (since you can’t scan your own screen). If you need a walkthrough for manual eSIM setup, that guide covers the process in detail.
Prerequisites Before You Install
Before attempting to install an eSIM on your Android device, confirm four things.
1. Your phone supports eSIM
Not every Android phone has the hardware. Three quick ways to check:
- Settings search: Open Settings and type “eSIM” or “SIM Manager.” If the option appears, you’re compatible.
- Dial code: Call
*#06#. If an EID (Embedded Identity Document) number appears alongside your IMEI, your phone has eSIM hardware. - Settings path: Navigate to Settings > About phone > Status > EID. If a number is listed, you’re good.
Regional gotcha for Samsung owners: Samsung phones purchased in the USA from a carrier frequently do not have eSIM enabled. This is one of the most commonly missed compatibility issues. If you bought a Samsung through a US carrier on a contract, verify before purchasing any travel eSIM.
Also worth knowing: most Android phones sold in mainland China have eSIM disabled due to government regulations. This applies to Samsung, Pixel, Xiaomi, and OnePlus models sold in that market.
2. Your phone is carrier-unlocked
A device can be technically eSIM-capable but still carrier-locked, which blocks activation from any other provider. If you bought your phone directly from Samsung, Google, or an unlocked retailer, it should already be unlocked. If you bought through a carrier on a payment plan, contact them to confirm. A locked phone can only install eSIMs from its locked carrier.
3. You have stable Wi-Fi
The eSIM profile downloads from a remote server. A flaky connection can corrupt the download. Use a reliable Wi-Fi network and disable any VPN or data-saving features before starting.
4. You have your QR code or SM-DP+ details ready
Your eSIM provider should have sent you either a QR code image or two pieces of text: an SM-DP+ server address and an activation code (sometimes called a matching ID). Have one or both ready before you open Settings.
How to Install eSIM on Android, by Device
This is where most guides fail. They treat Android as one thing when the menu paths are genuinely different across brands. Here’s the exact sequence for each.
Samsung Galaxy
- Open Settings > Connections > SIM Manager (on older One UI versions, this may say “SIM card manager” or “Mobile plans”).
- Tap Add eSIM or Add mobile plan.
- Choose Scan QR code or Enter activation code manually.
- If scanning: point the camera at the QR code. If entering manually: type the SM-DP+ address and activation code into their respective fields. Samsung typically uses two separate input fields.
- Wait for the profile to download. Tap Confirm when prompted.
- Optionally rename the eSIM (like “Travel Data”) and set your preferences for calls, texts, and data.
Google Pixel
- Open Settings > Network & Internet > SIMs.
- Tap + Add SIM, then select Download a SIM instead (this is Google’s phrasing for “add an eSIM”).
- Choose Scan QR code or Enter details manually.
- If entering manually: Pixel often accepts the full LPA string (formatted as
LPA:1$server-address$activation-code) in a single field. This is a key difference from Samsung. - Follow the on-screen prompts to complete the download.
Important Pixel note (May 2026): Numerous Pixel 9 and Pixel 10 owners have reported losing cellular service after their eSIM stopped working. Google has acknowledged this bug across multiple Issue Tracker threads but hasn’t issued a fix yet. Practitioners on Reddit speculate the issue is triggered by flashing new firmware rather than updating via OTA, and users who installed the Android 17 Beta have also reported it. If you’re on a Pixel, stick with OTA updates for now.
Xiaomi, OnePlus, and Other Brands
- Open Settings > SIM cards & mobile networks.
- Look for an eSIM or eSIM management section.
- Tap Add eSIM.
- Scan the QR code or enter the SM-DP+ details manually.
Not all Xiaomi or OnePlus models support eSIM. The feature is generally available on recent flagship and upper-midrange devices running MIUI 14+ or HyperOS, but budget models rarely include it. Check your EID first.

Key Terms Glossary
These are the terms you’ll encounter during the install process. Each one explained in plain language.
SM-DP+ Address (Subscription Manager Data Preparation Plus)
Despite the long name, this is just a server address. It’s the digital location where your eSIM profile is stored, waiting for your phone to download it. Think of it like a URL that points to your specific carrier plan. When you scan a QR code, the SM-DP+ address is embedded inside. When you install manually, you type it in yourself.
Activation Code / Matching ID
This is the unique identifier that tells the SM-DP+ server which specific eSIM profile belongs to you. The server might host thousands of profiles; the activation code is your claim ticket. Together, the SM-DP+ address and activation code form the complete information needed to install your eSIM.
LPA String
LPA stands for Local Profile Assistant. The LPA string is a single-line format that combines the SM-DP+ address and activation code, typically formatted as LPA:1$smdp.example.com$ACTIVATION-CODE-HERE. Pixel phones accept this as one input. Samsung phones usually require you to split it into separate fields, which trips up a lot of people.
EID (Embedded Identity Document)
A unique hardware identifier for your phone’s embedded SIM chip. If your phone has an EID, it has eSIM hardware. You’ll sometimes need to provide your EID to customer support for troubleshooting.
APN (Access Point Name)
The gateway between your phone and the carrier’s data network. Most eSIMs configure the APN automatically, but when they don’t, you’ll have no data despite showing signal bars. APN issues are one of the top three post-install problems.
Data Roaming
A setting that allows your phone to connect to networks other than your “home” carrier. Almost all travel eSIMs require data roaming to be turned on, even though the eSIM itself is designed for that destination. This is counterintuitive and catches people off guard.
Dual SIM Dual Standby (DSDS)
The mode that lets your phone use two SIM profiles simultaneously, one physical and one eSIM (or two eSIMs on newer devices). Both stay connected, so you can receive calls on your home number while using the travel eSIM for data.

Post-Install Setup
Installing the eSIM profile is half the job. These steps make sure it actually works.
Set Your eSIM as the Data Line
After you install an eSIM on Android, the phone may not automatically route data through it. Go to your SIM Manager (Samsung) or SIM settings (Pixel) and explicitly set the new eSIM as your preferred line for mobile data.
Enable Data Roaming on the Travel Line
This is the single most common reason travel eSIMs “don’t work” after install. The profile downloads fine, the signal bars appear, but nothing loads. Go to the eSIM’s settings and toggle data roaming on. Your eSIM provider should confirm whether this is needed, but the answer is almost always yes.
Label Your SIMs
Give your physical SIM a name like “Home” and your eSIM a name like “Travel.” This small step prevents confusion when your phone asks which line to use for a call or message. One clean setup that seasoned travelers recommend: physical SIM handles calls and SMS, eSIM handles all mobile data.
Timing for Travelers
Most travelers should purchase their eSIM three to seven days before departure. Install it at home on Wi-Fi. Then activate it the day before travel or upon arrival at the destination. As one commenter on the Rick Steves travel forum explained, you can install the eSIM and let it sit idle until you’re ready, then simply deactivate your home SIM and switch over. Some travelers do this on the flight itself, so the eSIM is already searching for a local tower the moment they land.

Common Errors and How to Fix Them
Practitioners on Reddit and travel forums consistently flag the same set of problems. Here’s what to watch for and how to resolve each one.
APN Didn’t Auto-Configure
Your eSIM shows signal but no data. This usually means the APN settings didn’t populate correctly during install. Go to your eSIM’s connection settings and check the APN. Your eSIM provider should list the correct APN details in their confirmation email or help documentation. Enter them manually if needed.
Data Roaming Is Off
Already mentioned above, but it’s worth repeating because it accounts for a huge percentage of “my eSIM doesn’t work” complaints. Toggle it on for the travel eSIM line specifically.
Wrong Line Selected for Data
Your phone might still be routing data through your physical SIM instead of the eSIM. Check SIM Manager and confirm the eSIM is set as the active data line.
QR Code Scanned from the Camera App
If you scan the QR code using your phone’s camera app instead of through the network settings menu, Android often redirects to a generic “Add plan” screen designed for wearables like smartwatches. The eSIM won’t install properly this way. Always start the process from Settings, not from the camera.
VPN Blocking the Download
A VPN can interfere with the connection to the SM-DP+ server. Disable any VPN, ad blocker, or data-saving feature before attempting to download the eSIM profile. Re-enable them after installation is complete.
eSIM Storage Full
Most Android phones can store between five and eight eSIM profiles, with one or two active at a time. If you’ve accumulated profiles from previous trips, new installs may fail silently. Delete old, unused eSIM profiles to free up space. You can always reinstall them later if your provider supports re-download.
The Pixel eSIM Bug (May 2026)
As noted earlier, Pixel 9 and Pixel 10 devices are experiencing a known eSIM failure. If your Pixel loses cellular service after a firmware flash, the current workaround is to avoid sideloading builds and stick with OTA updates. Google has acknowledged the issue but has not released a patch as of this writing.
Custom ROMs Break eSIM
If you’re running a custom ROM, eSIM probably won’t work. The feature depends on proprietary carrier services, secure hardware elements, and vendor-specific firmware that most custom builds can’t replicate. This isn’t a configuration issue; it’s a fundamental limitation.
Quick-Fix Checklist
When something goes wrong after you install an eSIM on Android, run through this sequence before contacting support:
- Turn airplane mode on for 15 to 20 seconds, then off again.
- Restart the phone (especially important on Samsung after first install).
- Confirm the travel eSIM is the active line for data.
- Turn on data roaming for the travel line.
- If there’s signal but no data, check the APN settings.

The Bigger Picture: eSIM-Only Is Coming
The shift away from physical SIMs is accelerating. In 2026, several phones have dropped the SIM tray entirely. The iPhone 17 Air is Apple’s first globally eSIM-only phone. US models of the iPhone have been eSIM-only since 2022. And the Google Pixel 10 in the US is also eSIM-only.
Understanding how to install an eSIM on Android isn’t just useful for travel. It’s becoming a basic requirement for using your phone at all.

Frequently Asked Questions
Can I install an eSIM without a QR code?
Yes. Every QR code contains two pieces of information: an SM-DP+ server address and an activation code. If you have those details in text form, you can enter them manually through your phone’s network settings. This is particularly useful when your QR code is displayed on the same device you’re trying to install it on.
How many eSIMs can an Android phone store?
Most Android devices store between five and eight eSIM profiles. However, only one or two can be active simultaneously (depending on your phone model and whether it supports dual active eSIM). You can switch between stored profiles without re-downloading them.
Does my phone need to be unlocked to use a travel eSIM?
Yes. A carrier-locked phone can only install eSIMs from its locked carrier. If you bought your phone outright from the manufacturer, it’s almost certainly unlocked. If you bought it through a carrier on a plan, contact them to confirm or request an unlock before purchasing a travel eSIM.
Can I install my eSIM before traveling and activate it later?
In most cases, yes. Many travel eSIM providers start the data countdown when you first connect to a local network at your destination, not when you scan the QR code. This means you can install at home on Wi-Fi days before your flight. Check with your specific provider to confirm their activation policy, as some plans start immediately upon installation.
What happens if I delete my eSIM?
Deleting an eSIM removes the profile from your phone entirely. Whether you can reinstall it depends on your provider. Some allow re-download of the same QR code; others treat it as a one-time use. If you have remaining data on the plan, contact your provider before deleting.
Why does my eSIM show signal bars but no internet?
This is almost always one of three things: data roaming is turned off, the wrong SIM is selected as the data line, or the APN settings didn’t auto-configure. Work through those three in order and the problem usually resolves itself.
Is the QR code method better than manual SM-DP+ entry?
Neither is better; they deliver the same result. The QR code is faster if you have a second device to display it on. Manual entry is more practical when you only have one phone and the QR code is on its screen. Think of them as two doors into the same room.
Do all Samsung Galaxy phones support eSIM?
No. Samsung’s flagship S series, Z Fold, and Z Flip lines support eSIM. The A series has very limited support. And as mentioned above, Samsung phones sold through US carriers often have eSIM functionality disabled even on supported models. Always check your EID before buying.
