eSIM basics

What is an eSIM?

A SIM card, without the card.

An eSIM (embedded SIM) is a chip built into your phone or tablet that stores a mobile plan digitally. There’s nothing to post, cut to size or swap at a kiosk.

You download your plan instead of inserting a card. Your phone then connects to partner networks, just as it would with a plastic SIM.

How it works

How it works in practice

A digital profile

When you buy a plan from Keep On Roaming, we send you a digital profile. You install it with one tap from your confirmation email or account, and it sits alongside your usual SIM.

Keep your usual number

Leave your home SIM in place for calls and texts, and use the eSIM for data while you’re away: maps, chat apps and email. Our eSIMs are data only, so they don’t come with a phone number. For calls, use apps such as WhatsApp.

Why travellers like it

Why people choose an eSIM

Ready before you land

Buy and install before you fly, then switch on data when you land. No queuing for a local SIM at the airport.

Nothing to lose

There’s no tiny card to drop on the tarmac or leave in a hotel safe.

Several plans, one phone

Store more than one plan on your phone and switch between them in Settings.

Good to know

  • Your phone must be unlocked

    It needs to support eSIM and must not be locked to one mobile provider.

  • The clock starts when you connect

    Each plan has a validity period, usually 7, 15 or 30 days. It starts when the eSIM first connects to a supported network, so you can install it early.

  • Turn on data roaming

    Your eSIM needs data roaming switched on to connect. Turn it on for the eSIM when you arrive.

  • One device at a time

    An eSIM works on one device at a time. To move it to a new phone, remove it from the old one first.
