Let's install your eSIM
Pick your device to get started …
An eSIM is a digital SIM — think of it as a downloadable version of a traditional physical SIM card. It's built into your phone and lets you connect to a mobile network without inserting a SIM card.
If you're traveling abroad, an eSIM is an affordable way to connect to a local network. With a prepaid data plan, you know exactly what you'll pay — no roaming charges to worry about.
Before eSIMs, travelers usually had a few options:
1. Buy a physical SIM card on arrival, which means removing your main SIM and temporarily losing your usual phone number.
2. Sign up for your carrier's roaming package, which is usually expensive per day.
3. Use pay-per-use roaming, which can get very costly if you don't keep an eye on it.
At TouriESIM, you only pay for the eSIM data plan based on your destination, number of days and data amount — the eSIM itself comes free with the plan.
Data plans start at just $3.49. See detailed prices for each destination on our eSIM store.
Ready to install your eSIM?
Pick your device and we'll guide you step by step …
We recommend installing your eSIM before your trip, while you have stable Wi-Fi at home. Installation only takes a few minutes, and your data plan doesn't start counting days until you connect to a network at your destination.
Once installed, check out our eSIM activation guide so your phone is ready when you land.
Yes. To install an eSIM, your phone needs an internet connection (Wi-Fi or mobile data) to download the eSIM profile. Once it's installed, you don't need Wi-Fi to activate or use the eSIM.
Note: each QR code can only be installed once, so don't delete the eSIM after installing it.
