How Much Travel Data Do I Need? A Practical Estimate

Picking an eSIM allowance is easier when you know what uses data. Here is how to estimate what you need for your trip.

What uses the most data

From lightest to heaviest:

Messaging (WhatsApp text, email without attachments)
Maps and ride-hailing
Web browsing
Voice calls over WhatsApp or other apps
Social media feeds, especially auto-playing video
Video calls
Streaming video and music

Check your own habits

Your phone already tracks how much data you use. On iPhone, look under Settings > Mobile Data. On Android, look under Settings > Network > Data usage. Divide a month's usage by 30 for a daily average.

Simple ways to stretch your data

Download offline maps before you leave.
Turn off video auto-play in social apps.
Set app updates and photo backups to Wi-Fi only.
Download music and shows before your flight.

Validity matters too

Choose a plan whose validity covers your whole trip, not just the data amount. A short validity with lots of data may expire before you use it.

Running low?

You can top up your eSIM from Manage my eSIM instead of buying a new one.
