How to install an eSIM on your phone

Two quick recipes — one for iPhone, one for Android — plus a little troubleshooting at the end.

How to do it on iPhone

01

Open Settings

Scroll down to Cellular. On older iOS: Mobile Data.

02

Tap “Add eSIM”

At the very bottom. Or “Add Cellular Plan”.

03

Choose “Use QR Code”

Point the phone at the QR code on the My eSIMs page. Or choose “Enter Details Manually” and paste the LPA code.

04

Follow the wizard

Apple walks you through it. Name the line e.g. “Turkey March 2026” — easy to tell apart later.

05

Choose default usage

Keep your main line for calls/SMS. Select the eSIM line for data while you're away.

06

Turn off roaming on your main line

Cellular → your main line → switch OFF “Data Roaming”. Saves you from expensive surprises.

TipOn iOS 17.4+ you can install the eSIM without scanning the QR — open the receipt on your phone and tap the link directly.

How to do it on Android

Menu names vary between manufacturers (Samsung, Pixel, OnePlus). Search for “eSIM” in settings if you can't find it.

01

Open Settings

Network & internet (or “Connections” on Samsung). Search for “eSIM” if you can't find it.

02

Tap “Download SIM”

Or “Add SIM” → eSIM. A plus icon on Pixel/OnePlus.

03

Scan the QR code

Choose “Scan QR” from the My eSIMs page. Or use the manual activation code.

04

Confirm the eSIM for data

Set the active eSIM as your data connection while you're away.

05

Turn off roaming on your main line

Your main SIM's settings → turn off “Data roaming”. Protects you from expensive surprises.

Troubleshooting

The eSIM won't activate

Wait 1-2 minutes after you land. Toggle airplane mode off and on. Restart the phone if needed.

No signal

Check that the right line is selected for data, and that roaming is ON for the eSIM line.

The QR code won't scan

Use “Enter Details Manually”. You'll find the SM-DP+ address and activation code in your receipt.

I lost my QR code

Sign in to My eSIMs with your email — all your codes are there.
