What the app does that this website does not
What makes an eSIM easier to live with once you have one, plus an optional VPN.
Your data left, live
See what is remaining without opening an email or signing in on a browser. The figure comes from the network, not from an estimate of what you have probably used.
- A warning before you are cut off
- Every eSIM in one place
- Home-screen widget, so you do not even open the app
Top up in two taps
On plans that take a top-up, add data to the eSIM that is already installed. No reinstall and no second QR code. Each top-up option says what it does to the plan you are on.
One-tap install, checked
The app walks you through it and confirms the install worked.
The right plan for every trip
Filter by trip length and data, or answer two quick questions and let the app pick. Country and regional plans sit in one list.

Install before you fly
One tap installs the eSIM. It starts when you land, so nothing is used at home.
You do not need the app to buy
Every plan on this site works in a browser, and your QR code arrives by email either way. The app is not a gate on buying. It is where managing an eSIM gets easier once you have one.
Get your eSIMWill I lose my phone number?
No. Your home SIM stays in the phone and keeps your number, so calls, SMS and WhatsApp carry on as normal. The SimFuse eSIM is a second line for data, plus calls or texts only on plans that list them. Nothing about installing the app changes which number you are reachable on.
Does my phone support eSIM?
Most iPhones from the XR onward and most flagship Android phones from 2020 onward do, but carrier-locked and some region-specific models do not. Check yours before you install anything.
Check whether your phone supports eSIM โFrequently asked questions
No. You can buy any plan on this website and install it from the QR code that arrives by email. The app is for watching your data afterwards, and for topping up on plans that take one.
Yes. Installing it costs nothing and there is no subscription. You pay only for the data plans you choose to buy.
No. The eSIM is installed on the phone itself, not inside the app. Deleting the app leaves your data connection running. You just lose the easy way to check usage, and to top up where your plan allows it.
Yes, on plans that take a top-up, and each plan says whether it does. A top-up adds data to the eSIM already on your phone, with no second QR code and nothing to remove and set up again.

Yes, on the App Store and on Google Play. Sign in with the same SimFuse account on either one and the eSIMs you bought under that account are already there.
Yes, as an optional paid add-on. SimFuse VPN runs alongside a SimFuse eSIM and protects your phone on every connection: the eSIM, Wi-Fi and your home SIM. You pay once for the days you choose, and nothing renews.
