eSIM for travel: cheap mobile data abroad

Within your home region your data plan usually just works. But travel further. Asia, the Americas, the Caribbean, and roaming can get frightening. An eSIM is the cheap fix.

What is an eSIM?

An eSIM is a digital SIM already built into your phone. Instead of swapping a physical card, you activate a data plan from a local or global provider with a QR code. Your own SIM (and number) stays active.

Why it saves money

Roaming outside your region often charges per MB or via pricey daily passes. A travel eSIM sells you a data bundle for your destination at local rates, a fraction of roaming. You buy exactly as much data as you need.

How to set it up

1. Check your phone supports eSIM (most recent handsets do). 2. Buy a data plan for your destination or region before you leave. 3. Install the eSIM via the QR code, do this at home on wi-fi. 4. On arrival, turn on data roaming for the eSIM and you're online.

Combine it smartly

• Set your normal SIM to calls/texts only and use the eSIM for data.
• Estimate your usage: maps, chat and navigation are light; video streaming is heavy.
• Download offline maps and your boarding pass before you go.

That way you step off at your destination with no surprises, on a ticket you found cheap with Flights. Going far? Read how to find cheap long-haul flights too.
