An eSIM is a digital SIM card built directly into your phone.
Instead of slotting in a physical SIM when you travel, you install a Nimbus eSIM at home over Wi-Fi - and your phone connects to a local network when you land. Your home SIM stays exactly where it is. The eSIM sits alongside it.
An eSIM (embedded SIM) is a digital SIM card built into your phone or tablet. It works like a physical SIM but doesn't require a card. With a travel eSIM, you can use a local data plan in another country without swapping your physical SIM.

eSIM vs Physical SIM

Step 1
Choose your destination and how much data you need in the Nimbus app.

Step 2
Install your eSIM over Wi-Fi at home. Quick by design.

Step 3
Arrive, turn off airplane mode, and you're online.
For detailed install instructions for your specific phone - iPhone, Samsung, or Pixel - we have illustrated guides in our Knowledge Base.


Myth 1
No. The Nimbus eSIM sits alongside your home SIM. Calls and texts to your usual number still come through - you just use the eSIM for data while you're abroad.

Myth 2
The opposite, actually. Install your eSIM at home over Wi-Fi before you travel. It stays dormant until your phone connects to a local network at your destination - that's when the plan starts.

Myth 3
Probably not. Most flagship phones from the last four years support eSIM - iPhone 12 and newer, Samsung Galaxy S22 and newer, Pixel 6 and newer. Check the full list of supported devices.

Myth 4
They're not. Install takes a couple of minutes over Wi-Fi at home - scan a QR code or open the Nimbus app. Activation on arrival is automatic.
