2. Open Settings → Connections → SIM manager

3. Tap Add eSIM

4. Tap Scan QR code from service provider

5. Point your camera at the QR code

6. Wait for the activation (may take 30 seconds to 2 minutes)

Samsung tip: If you use Samsung's Dual SIM feature, you can keep your home SIM for calls and texts while using the Japan eSIM for data. Go to SIM manager → Preferred SIMs → Mobile data and select the Japan eSIM.

Setup: Google Pixel

1. Purchase your eSIM plan

2. Open Settings → Network & internet → SIMs

Setup: Other Android Phones

The process is similar across most Android 12+ phones:

1. Settings → Network → SIMs → Add eSIM

2. Scan QR code

3. Confirm and activate

If your phone doesn't have "Add eSIM":

• Check if your carrier has locked the eSIM slot
• Some budget phones have eSIM hardware but it's not enabled in all regions
• Contact your carrier to check

APN Settings (If Needed)

Most Japan eSIMs configure automatically. If you're not getting data after activation:

1. Go to Settings → Connections → Mobile networks → Access Point Names

2. Tap + Add or New APN

3. Enter the APN details from your eSIM provider (check their email or app)

4. Save and select the new APN

Common APNs:

• Airalo: `globaldata` (usually auto-configured)
• Ubigi: `ubigi` (sometimes needs manual entry)
• Saily: auto-configured

Troubleshooting

No Signal After Installation

1. Make sure the eSIM is set as your mobile data SIM

2. Enable Data Roaming: Settings → Connections → Mobile networks → Data roaming → ON

3. Restart your phone

4. Try manual network selection: Settings → Connections → Mobile networks → Network operators → Search manually

QR Code Won't Scan

• Make sure your camera is in focus and the QR code is well-lit
• Try entering the activation details manually (SM-DP+ address and activation code)
• Check if you have a stable WiFi connection during setup

"SIM Not Supported" Error

• Your phone may be carrier-locked. Contact your carrier to unlock it.
• Some carriers lock the eSIM slot even on "unlocked" phones. Ask specifically about eSIM unlock.

Android vs iPhone eSIM: Key Differences

| | Android | iPhone |

|---|---|---|

| eSIM support since | 2018 (Pixel 3) | 2018 (XS) |

| Consistency | Varies by brand/model | Universal from XS onward |

| Setup | QR code scan | QR or Airalo app (no QR) |

| APN config | Sometimes manual | Almost always automatic |

| Dual SIM management | Brand-specific UI | Consistent Apple UI |

Bottom line: iPhone eSIM setup is slightly smoother, but Android works perfectly well once installed. The eSIM itself performs identically on both platforms.
