What is an eSIM?

A simple guide to the digital SIM: how it works, what it’s good for and how to use one when you travel.

What exactly is an eSIM?

An eSIM (embedded SIM), sometimes written e-SIM, is a digital SIM built into your phone, tablet or smartwatch. Instead of inserting a plastic SIM card, you download a mobile plan by scanning a QR code. Once it’s installed, it connects you to a mobile network just like a physical SIM.

Compared with a physical SIM card, that means:

  • No tiny tools, no SIM trays and no cards to lose.
  • You can buy and install a plan before you leave home.
  • Most eSIM phones take a physical SIM too, so you can keep your usual SIM alongside a travel eSIM.

With an eSimpli eSIM, you can sort out mobile data before you travel, so you can focus on your trip rather than your phone.

How does an eSIM work?

Your device stores an eSIM as a profile. When you buy a plan, you scan a QR code and your phone downloads that profile over the internet. No shop visit, no card swap.

You can keep several profiles on one device and switch between them in Settings. Install your eSimpli eSIM on Wi-Fi before you travel; our installation guide walks you through each step on iPhone and Android.

Why choose an eSimpli eSIM?

Find your destination

Travel flexibility

Connect to local mobile networks abroad without hunting for a SIM card at the airport. Buy your plan before you go.

Multiple profiles

On most eSIM phones, keep your usual SIM for calls and texts and use an eSimpli eSIM for data, or store plans for different trips on one phone.

No physical card

Your phone’s eSIM is built in, so adding a plan means a download, not a SIM swap.

Install from anywhere

Install your eSimpli eSIM at home, at the airport or on the go. All you need is an internet connection.

Does my phone support eSIM?

Not every phone supports eSIM yet. Most recent iPhone, Samsung Galaxy and Google Pixel models do, but older models may not. Your phone also needs to be carrier-unlocked.
