How to Install an eSIM on Android (Pixel, Samsung, and Beyond — 2026 Guide)

Android's eSIM support has improved dramatically since the Pixel 3 introduced consumer eSIM in 2018. By 2026, every flagship Android of the past five years supports eSIM, and the install flow is essentially identical across phone brands — though menu paths differ slightly. Here is the complete how-to for the most common Android phones.

Confirm your phone supports eSIM

The fastest test: Settings → Network & Internet → SIMs (or Mobile network). If you see "Add eSIM" or "Download a SIM" or "+" to add a line, your phone supports eSIM. If you only see options for physical SIMs, it doesn't.

Quick reference:

• Pixel 3 onward — supports eSIM
• Samsung Galaxy S20, S21, S22, S23, S24 onward — supports eSIM (most regional variants)
• Samsung Galaxy Z Flip 3+, Galaxy Z Fold 3+ — supports eSIM
• Motorola Razr 2022+, Razr 40+, Razr 50+ — supports eSIM
• OnePlus 11, 12, 13 — supports eSIM (most regions)
• Xiaomi 12, 13, 14 — supports eSIM (varies by region)
• Oppo Find X5+, Reno 8+ — supports eSIM (most regions)

Mid-range Androids are mixed — when in doubt, the Settings test above is definitive.

Method 1: Install from a travel eSIM provider's app (Pixel)

This is the easiest path on Pixel.

1. Buy a plan in the provider's app. Open eSimphony (or Airalo / Holafly / Saily), pick destination, plan, pay.
2. Tap "Install eSIM." The provider app hands off to Android's eSIM installer.
3. Confirm the eSIM details. Android shows the carrier name and plan; tap "Download" or "Activate."
4. Wait for download. Pixel takes 30–60 seconds to fetch the profile.
5. Name the line. Pick something obvious like "Travel France."
6. Set defaults. Pixel asks which line to use for cellular data, calls, and texts. For most travelers: keep your home line for calls and texts, use the eSIM for cellular data.

The eSIM appears as a new entry in Settings → Network & Internet → SIMs.

Method 1b: Install from a travel eSIM provider's app (Samsung Galaxy)

Samsung's flow is similar but the menus look different. The first time you install an eSIM through a third-party app, Galaxy may prompt you to grant the app eSIM-installation permission.

1. Buy a plan. Same as above.
2. Tap "Install eSIM" in the provider app.
3. Grant permission if prompted. Samsung may ask for permission to manage eSIM. Approve.
4. Confirm the eSIM details in the system prompt.
5. Wait for download and name the line.
6. Set Default SIM for data — Settings → Connections → SIM Manager → Mobile data → select the travel eSIM.

Method 2: Install from a QR code

If your provider hands you a QR code (older flow), the steps:

Pixel:

1. Settings → Network & Internet → SIMs → "+" or "Add eSIM"
2. "Download a new SIM" → "Next"
3. Scan the QR code with the camera
4. Confirm the carrier
5. Name the line and set defaults

Samsung Galaxy:

1. Settings → Connections → SIM Manager → "Add mobile plan" or "Scan carrier QR code"
2. Scan the QR code
3. Confirm and download
4. Name the line

If you only have one screen and the QR code is on the same phone, save the QR code as an image and use the "From gallery" option that most Android cameras offer.

Method 3: Install from a deep link (one-tap)

eSimphony and a few other providers support deep-link installs that skip the QR step. Tap the link in the provider app or in an email/SMS the provider sent, and Android opens the eSIM installer directly.

This is the fastest path. Recommended.

Configuring the line after install

Take 30 seconds to make sure the lines are set up the way you want.

Pixel:

• Settings → Network & Internet → SIMs → tap the new eSIM
• Confirm "Use SIM" is on
• Settings → Network & Internet → SIMs → "Mobile data" → select the travel eSIM
• "Calls" → keep your home line (typically)
• "SMS messages" → keep your home line

Samsung Galaxy:

• Settings → Connections → SIM Manager
• Make sure both lines (home + travel eSIM) show as active
• Tap "Mobile data" and select the travel eSIM
• Tap "Calls" and "SMS" → keep on the home line
• Optionally enable "Allow data switching" so the phone falls back to the home line if the eSIM loses signal

Hotspot / tethering on Android with eSIM

Most providers allow hotspot from a travel eSIM, but check the plan details. To enable on Android:

Pixel: Settings → Network & Internet → Hotspot & tethering → Wi-Fi hotspot → On. Make sure the "Mobile data" line in SIM settings is the travel eSIM, otherwise hotspot will use your home line and burn through home data.

Samsung Galaxy: Settings → Connections → Mobile Hotspot and Tethering → Mobile Hotspot → On.

A common pitfall: hotspot starts but uses the wrong SIM. Always confirm "Mobile data" is set to the travel eSIM before turning on hotspot.

Troubleshooting common Android-specific errors

"Unable to add eSIM." Usually means no internet connection during install or a carrier-locked phone. Connect to Wi-Fi and retry. If your phone is locked, contact your home carrier.

eSIM downloaded but no signal. Check that "Use SIM" is enabled for the line and "Mobile data" is set to that line. Toggle Airplane Mode for 10 seconds.

"This SIM is not supported." Some Pixel phones running older builds reject certain eSIMs. Update to the latest Android version (Settings → System → System update).

Samsung Galaxy keeps switching to physical SIM. Settings → Connections → SIM Manager → confirm "Allow data switching" is on or off as you intend. With it on, Galaxy may auto-fallback when one line has weak signal.

Activation pending forever. Same as iPhone — wait 5–15 minutes, force-close the provider app, retry. If still stuck, contact support for a re-issue.

Removing an old eSIM

When a plan ends or you no longer need the eSIM:

Pixel: Settings → Network & Internet → SIMs → tap the eSIM → "Erase SIM"

Samsung Galaxy: Settings → Connections → SIM Manager → tap the eSIM → "Remove"

If you're using eSimphony's lifetime eSIM, don't remove it — the profile is meant to stay installed forever. Just turn the line off if you don't need it right now.

Transferring eSIMs to a new Android phone

Unlike physical SIMs, you can't just move an eSIM by swapping cards. Most travel eSIM providers require you to reinstall on the new phone (the provider's app handles this — sign in to your account on the new phone and re-trigger the install).

For eSimphony specifically, the lifetime eSIM gets reinstalled on the new phone using the same account; your purchase history and remaining plans follow you. There's no need to "transfer" because the eSIM data lives in our cloud account.

Pixel-to-Pixel and Galaxy-to-Galaxy transfers via Google's "Transfer Your Data" or Samsung's "Smart Switch" do not migrate eSIMs automatically.

Brand-specific quirks

Pixel: Best eSIM experience on Android. Native UI is clean, install is fast, no carrier shenanigans.

Samsung Galaxy: Reliable but the menu names change between One UI versions. The "SIM Manager" name is consistent in recent versions.

Older Korean Galaxy phones: May not support eSIM at all due to historical Korean carrier policies. Newer Korean Galaxy phones have started supporting it.

Chinese-market phones (Xiaomi, Oppo, Vivo for the China market): Often shipped without eSIM support. International variants do support it.

Motorola Razr foldables: Excellent eSIM support, fast install.

OnePlus: Good eSIM support on flagship phones (11, 12, 13). Some older or India-market models do not support eSIM.

What's coming next

Android's eSIM support is converging on a consistent UX across brands — the GSMA's SGP.32 specification is pushing all manufacturers toward the same install flow. By the late 2020s expect the install experience to be essentially identical regardless of brand.

If you want to skip QR codes entirely, download eSimphony. Our install is one tap on Pixel and Galaxy, our lifetime eSIM means you only set up once, and Moza picks plans for you each trip so you don't have to think about which package fits where.
