eSIM explained: what it is and how it works

An eSIM is a digital SIM built into your phone. Instead of inserting a plastic card, you download a data plan in minutes – ideal for travelling without roaming fees and without swapping SIM cards.

What is an eSIM?

eSIM stands for “embedded SIM”: a small chip that is permanently built into your device. It does everything a physical SIM card does and connects you to a mobile network, but the plan is installed digitally, by scanning a QR code or tapping a button in an app.

Most current smartphones, tablets and smartwatches support eSIM. One device can store several eSIM profiles, so you can add a travel data plan next to your usual contract and switch between them in your settings.

How does an eSIM work?

Your eSIM is pre-installed software. Once a plan is downloaded, your phone connects to a local network just like with a physical SIM.

    Your own SIM stays active for calls and SMS while the eSIM handles data.

    Store several eSIM profiles and switch between them in settings.

eSIM limitations

eSIM is simple, but not perfect for everyone. Here’s what to check before you buy, so your travel data works from the first minute.
  • Device must support eSIM. Most phones from 2018 onwards do – check your model before you buy.
  • Internet needed to install. Install your eSIM over Wi-Fi, ideally before you leave home.
  • Moving to a new phone. An eSIM is tied to one device. Switching phones may need a new installation.

eSIM vs. physical SIM: what’s the difference?

The main difference: an eSIM is a digital profile on a chip built into your device, while a physical SIM is a removable plastic card.

Frequently asked questions about eSIMs

Find helpful information to answer your questions.

Is an eSIM better than a physical SIM?

For travelling, usually yes: you buy it online, install it in minutes and keep your own SIM for calls. A physical SIM is only needed if your phone doesn’t support eSIM.

Can I use an eSIM and a physical SIM at the same time?

Yes. Most eSIM phones support dual SIM: your physical SIM keeps your number, the eSIM provides mobile data abroad.

Do I get a phone number with ArabSIM?

No. ArabSIM eSIMs are data-only. You can still call and message via VoIP apps such as WhatsApp or Telegram.

When does my eSIM plan start?

The validity period starts when your eSIM first connects to a supported network at your destination – not when you install it.

Does an eSIM work without an internet connection?

You need Wi-Fi or mobile data once to install the eSIM. After that it works on its own.

Is an eSIM safe?

eSIM profiles are encrypted and can’t be removed and used in another phone like a stolen SIM card.

Does an eSIM drain my battery?

No more than a physical SIM. Using two lines at once can use slightly more power.

Can I reuse my eSIM on another trip?

Each eSIM plan is valid for one trip. For your next trip, simply buy a new eSIM plan.
