What if the QR code doesn't scan?

Try improving the lighting or holding your phone steadier. If the QR code is on a screen, increase brightness and reduce glare. Most providers also offer a manual activation code you can type in instead — check your confirmation email for an alternative method.

Can I set up my eSIM without WiFi?

You need an internet connection to download the eSIM profile. WiFi is easiest, but your existing cellular data works too. This is exactly why I recommend setting up at home before your trip — your home WiFi is reliable, airport WiFi often isn't (I learned that one in Paris).

How do I switch between my physical SIM and eSIM?

On iPhone: Settings → Cellular → select which line to use for data. On Samsung: Settings → Connections → SIM manager. On Pixel: Settings → Network & internet → SIMs. You can set your eSIM for data and physical SIM for calls/texts.

My eSIM says 'No Service' after activation. What do I do?

First, ensure the plan is active (some start on a specific date). Try toggling Airplane Mode on/off, or restart your phone. Check that Data Roaming is enabled (Settings → Cellular → your eSIM line → Data Roaming). If the issue persists, contact your eSIM provider's support.

Can I remove and reinstall my eSIM?

You can remove an eSIM profile from your phone, but reinstalling depends on the provider. Some allow re-scanning the same QR code, while others issue a new code. Before removing, check with your provider whether the plan can be reactivated.

Should I activate my eSIM before or after arriving at my destination?

Before. Always before. I cannot stress this enough — I tried activating after landing on my first eSIM trip and spent 20 frustrating minutes fighting airport WiFi while my wife waited. Most plans let you pre-activate 24-48 hours before your start date. Set it up on your couch at home, verify it's installed, and it'll be ready to connect the moment you land.

How to Set Up eSIM — iPhone, Samsung & Pixel Guide

Before You Start

I overthought this my first time. It actually takes about 5 minutes — less time than ordering coffee at an airport Starbucks. Before you start, just make sure you have:

Compatible device

iPhone XS+, Samsung S20+, Pixel 3+, or other eSIM-capable phone

WiFi connection

You need internet to download the eSIM profile (existing mobile data also works)

QR code ready

Have your eSIM provider's QR code or activation link accessible on another screen or printed

Updated software

Make sure your phone is running the latest OS version for best compatibility

Learn From My Mistake: Set Up Before You Fly

On my first eSIM trip — my honeymoon in Paris, January 2023 — I made the classic rookie mistake of trying to activate my eSIM afterlanding at Paris Orly Airport. The airport WiFi was barely functional, and I was standing in the arrivals hall with my wife trying to figure out how to get to our hotel without data. Don't be me. Install your eSIM before you leave home. Most plans can be set up 24-48 hours before your trip starts, so you'll have data the second your plane touches down.

Troubleshooting Common Issues

QR code won't scan

Increase screen brightness, ensure camera is in focus, or try the manual activation code from your confirmation email.

"eSIM not supported" error

Verify your device model supports eSIM and that your carrier hasn't locked eSIM functionality. Some carrier-locked phones restrict eSIM use.

No data after activation

Toggle Airplane Mode on/off. Check that Data Roaming is enabled for the eSIM line. Restart your phone. Verify the plan's start date has begun.

Slow speeds

Check if you've exceeded your data cap (throttled plans slow down after the limit). Try toggling between 4G/5G in your network settings.
