You’re going abroad and you need data — for maps, messaging, ride apps and a hundred small things. But what’s the best way to get it in 2026? You’ve got three real options: roam on your home plan, buy a local SIM on arrival, or load a travel eSIM. Here’s an honest comparison so you can pick the one that saves you the most stress and money.
Option 1: Roaming on your home plan
How it works: you simply use your phone abroad and your provider bills you for foreign usage.
Pros: zero setup — it just works.
Cons: often the most expensive option by far, unless your plan specifically includes the country with a fair allowance. A few days of normal use can produce an alarming bill.
Verdict: fine only if your plan clearly includes generous roaming for your destination. Otherwise, avoid.
Option 2: A local SIM bought on arrival
How it works: you buy a physical SIM at the airport or a shop in the destination country.
Pros: usually cheap local rates.
Cons: you have to queue, sometimes show ID, swap out (and risk losing) your home SIM, and you lose access to your home number while the foreign SIM is in. It also wastes time you’d rather spend exploring.
Verdict: cheap but inconvenient, and you sacrifice your home number.
Option 3: A travel eSIM
How it works: you buy a digital plan for your destination and install it by scanning a code — before you even leave home.
Pros: local-style rates, set up in minutes, no queue, and your home number stays active alongside it. You can install before you fly and switch it on when you land.
Cons: your phone needs to support eSIM (most recent phones do).
Verdict: for most travellers, the best balance of price and convenience. Browse options in our travel eSIM range.
Why the eSIM usually wins
A travel eSIM combines the cheap rates of a local SIM with the zero-hassle setup that roaming promises but overcharges for. You keep your number, skip the airport queue, and know the price upfront. Match the plan to your trip and it’s almost always the smartest choice:
- One country: a single-country plan is cheapest.
- One region: a Europe eSIM, Asia eSIM or North America eSIM covers multiple countries on one plan.
- Multiple continents: a Global eSIM follows you everywhere.
Avoiding bill shock, step by step
- Before you fly, buy and install the right eSIM on home Wi-Fi.
- On arrival, switch it on and set it as your data line.
- Turn off data roaming on your home line so it can’t bill you.
- Keep your home number active for calls and security codes.
- Download offline maps and set backups to Wi-Fi only.

How much should you buy?
Budget around a gigabyte a day for typical use — maps, messaging, social and a little video — and more if you stream or tether. A daily allowance suits short trips; a larger bundle suits longer stays. You can always top up, so there’s no need to over-buy.
The bottom line
In 2026, the best way to get data abroad for most people is a travel eSIM: local-style pricing, two-minute setup, your number kept live, and the cost known before you travel. Roaming is the convenient-but-costly trap; a local SIM is cheap-but-clunky; the eSIM gives you the best of both. Sort it before you go and travel without a second thought.
