Before installing (or, before buying) - just check: is my phone compatible with eSIM?

It might sound obvious, but of course you aren’t going to be installing any eSIMs in a hurry if your phone simply is not an eSIM-compatible, unlocked phone. But fear not - these days most of the flagship models of major manufacturers support eSIM, so don’t get left behind!

How To Install an eSIM

Installing an eSIM is simple and usually takes just a few minutes. There are two main ways to install an eSIM:

QR code (most common)
automatic or manual setup via app

In most cases, you’ll receive installation instructions after purchasing your eSIM plan.

Method 1: Install eSIM using a QR code (recommended)

This is the easiest and most common method.

On iPhone:

Go to Settings → Cellular → Add eSIM
Select Scan QR Code
Scan the QR code provided

On Android:

Go to Settings → Network & Internet / SIM Manager
Tap Add eSIM / Add Mobile Plan
Scan the QR code

Once scanned, your device will download and install the eSIM profile automatically.

Method 2: Install eSIM via app (automatic installation)

Some providers (like Nomad eSIM) allow direct installation through their app.

Steps typically include:

Open the app
Go to your purchased plan
Select Install eSIM
Follow on-screen instructions

This method removes the need to scan a QR code and is often the fastest option.

Manual installation (backup option)

If QR code or app installation doesn’t work, you can install manually.

Go to Add eSIM → Enter details manually
Input the activation details provided

This method is less common but useful in certain situations.

When should I install my eSIM?

You should install your eSIM before you travel.

Installation requires internet connection
Activation usually happens later when you connect to a network

Installing early ensures you’re ready once you land and there is no need to rely on airport WiFi.

What should I do after installing my eSIM?

Once installed:

turn on your eSIM in settings
select it for mobile data
enable data roaming

When you reach your destination, your eSIM will connect automatically.

What if I can’t install my eSIM?

Common fixes:

ensure you’re connected to WiFi
check your phone is eSIM-compatible
make sure the QR code hasn’t already been used (it’s one-time use)
restart your device

If issues persist, you can try manual installation or contact support.

Can I install multiple eSIMs?

Yes. Most devices allow:

multiple eSIM profiles stored
switching between them in settings

However, only one (or two, depending on device) can be active at a time.
