What you can do in the app
Buy in under a minute
Pick a destination, choose a plan, pay. The eSIM lands in the app straight away, no email to hunt for.
Install with one tap
No QR code to scan from another screen. The app installs the profile on the phone it is running on.
See what is left
Live data balance and days remaining, so running out never comes as a surprise at the airport.
Top up mid-trip
Two taps to add more data on the plan you are already using. Your number and your line stay exactly as they are.
Keep your own number
Your physical SIM stays in the phone. Calls, SMS and bank codes keep arriving on the number you already use.
Support in your language
Write from inside the app and get an answer in the language you wrote in. We work in 31 languages.
Install without the QR dance
Buying an eSIM usually means opening an email on one screen and scanning a QR code with another. In the app there is no second screen: the profile installs on the phone that is already in your hand.
A free VPN travels with you
Every active Cellesim eSIM comes with a free VPN key, built into the app. Use hotel and airport Wi-Fi without handing your traffic to whoever runs the network, and reach the apps you use at home from countries that restrict them.
- No separate signup, no extra cost
- Works while your eSIM is active
- Set up from inside the app

Before you download
Is the app free?
Yes. Downloading and using the app costs nothing. You only pay when you buy a data plan.
Do I need the app to use a Cellesim eSIM?
No. You can buy and install from the website with a QR code. The app makes installing and topping up easier, especially once you are abroad.
Will I lose my own number?
No. Your physical SIM stays in the phone and keeps handling calls, SMS and bank codes. The Cellesim line carries data only.
Which phones work?
Any eSIM-capable iPhone or Android that is carrier unlocked. The app checks your device before you buy.
