How Much Data Do You Need Abroad? A Realistic Guide by Activity (2026)

"How many GB do I need?" is the question travelers ask most before buying a travel eSIM — and the one most often answered with a guess. Buy too little and you are topping up in a taxi queue; buy too much and you paid for data that expires unused.

The good news: mobile data use is surprisingly predictable once you break it down by activity. Here is what each common thing actually costs, and how to turn it into a plan size.

What common activities really use

ActivityApproximate use
Messaging (text, no media)Under 1 MB per hour
Google Maps / Apple Maps navigation5–10 MB per hour
Browsing, email, ride-hailing apps30–60 MB per hour
Instagram / TikTok scrolling150–300 MB per hour
Music streaming (standard quality)60–70 MB per hour
Video call (WhatsApp, FaceTime)200–400 MB per hour
Video streaming (HD)1–3 GB per hour

These are ballpark figures — they shift with app, quality settings and signal — but they are accurate enough to plan with.

Three traveler profiles

  • The light user: about 300–500 MB per day. Maps, messaging, a few photos, the odd restaurant search. A 3 GB plan covers a week comfortably.
  • The typical tourist: about 1 GB per day. Add social media, ride-hailing, translation apps and uploading photos. A 5 GB plan suits a long weekend to a week; 10 GB covers ten days.
  • The heavy user or remote worker: 2–3 GB or more per day. Video calls, streaming, cloud backups or using your phone as a hotspot for a laptop. Choose a 20 GB plan or an unlimited daily plan.

Easy ways to stretch your data

  • Download offline maps for the city or region before you leave — navigation then costs almost nothing.
  • Switch off auto-play and HD in Instagram, TikTok and YouTube; video is the fastest way to burn through a plan.
  • Use hotel and café WiFi for the heavy stuff: app updates, photo backups, downloading shows for the flight home.
  • Turn off background app refresh for apps you don't need live — it is a quiet drain on every phone.

A simple rule for picking a plan

Estimate your daily use from the profiles above, multiply by the number of days, then choose the next size up. Running out mid-trip costs more in friction than the couple of euros you save by buying tight. Not sure which side of the line you fall on? Choose a plan that can be topped up — you can always add data without reinstalling anything.

Setup takes about two minutes and works before you fly; the installation guide walks you through it, and the compatibility list tells you whether your phone is ready.

FAQ

Does the plan include hotspot / tethering?

Yes, plans from eSIM Agora allow tethering. Keep in mind that a laptop uses data much faster than a phone, so size your plan up if you plan to work from it.

What happens when my data runs out?

The connection stops until you top up. You can add data from your account without installing a new eSIM, and your home SIM keeps working for calls and SMS in the meantime.

Is it better to buy one big plan or several small ones?

For one trip, a single plan sized to your total need is simpler and usually better value. For a multi-country journey, a regional plan beats one eSIM per country — see our Europe multi-country guide.
