Three things define an eSIM plan: where it works, how long it lasts, and how much data it includes. Let us take them in order.
1. Where it works: country or region plan?
- Travelling to one country? The single-country plan is almost always the cheapest option.
- Hopping between countries (a Europe trip, for instance)? A regional plan is both cheaper and simpler than buying one plan per border.
- A layover does not count as a destination - airport Wi-Fi is usually enough, so you do not need a plan for the country you connect through.
2. How many days?
Buy slightly more than your trip length. Delayed flights, a long final day at the airport and time-zone shifts move the end date more often than people expect. On a nine-day trip, a ten-day plan beats being offline on day nine.
3. How many GB?
This is where most people guess wrong. Nobody knows their own GB usage - but everyone's phone records their daily screen time. Our calculator turns those minutes into gigabytes.
Open the data calculatorEnter the Screen Time figures from your phone and get a daily and total GB recommendation.| What kind of traveller you are | Mobile data per day | For 7 days |
|---|---|---|
| Maps and messaging, everything else on hotel Wi-Fi | ~0.3 GB | 3 GB |
| Social feeds, some video, daily posting | ~0.8 GB | 5-10 GB |
| Constant streaming, video calls, hotspot | ~2 GB and up | 20 GB or unlimited |
Running out does not mean reinstalling anything: you can add data to the same line from your account. When you are torn between two sizes, the smaller one plus a top-up is usually cheaper than over-buying upfront.
What does "unlimited" mean?
Unlimited plans never run out of data, but speed may drop after a certain volume (fair usage). Worth it if you stream for hours or work off a hotspot; unnecessary for maps and messaging.
Network and speed
Each product page lists the local carriers you will connect to and whether 4G/5G is supported. Spending time outside the cities? Pick the plan listing the carrier with the widest coverage. Staying downtown? You will not notice a difference.
