How Much Data Do I Need When Traveling?

Too little data is frustrating, too much is money wasted. How much you really need depends less on the length of your trip than on your habits. If you mostly navigate and use WhatsApp, you need surprisingly little. If you watch Reels and post Stories, you need many times more. This overview helps you find the right plan.

Data usage of typical apps

These are estimates and vary with quality settings, network and app version.

Three types of travelers

Light: maps and messaging

You use Google Maps, send messages, look up opening hours and make the occasional voice call. Streaming and social media wait for hotel Wi-Fi. That takes about 150–300 MB per day, so 1–3 GB is usually enough for a week.

Average: social media and planning on the go

You post photos, watch Stories, book tickets and restaurants on the go and make the odd video call. Plan for 0.5–1 GB per day. For one week, 5–10 GB is realistic; for two weeks, 10–20 GB.

Heavy: streaming, hotspot and remote work

You watch Reels, stream shows, share a hotspot with your laptop or work remotely with video calls. 2–5 GB per day is easily reached here. A large plan of 20 GB or more, or an unlimited plan, makes sense. Be aware that many unlimited plans slow down after a daily limit and restrict hotspot use.

Recommendations by trip length

• Weekend or city break (2–4 days): 1–3 GB
• One-week beach vacation: 3–5 GB
• Two-week tour: 10–20 GB
• Three to four weeks of backpacking: 20 GB or more, or unlimited
• Workation / remote work: unlimited or 50 GB and up

Example: a one-week city trip

Say you spend seven days in a big city and are out for about ten hours a day. A typical day could look like this:

• 2 hours of Google Maps navigation: about 30 MB
• Messaging with a few photos and two short voice calls: about 30 MB
• 20 web pages, reviews and ticket bookings: about 80 MB
• 30 minutes of Instagram with Stories: about 100 MB
• One hour of music streaming: about 60 MB
• Two uploaded Stories: about 100 MB

That adds up to roughly 400 MB per day, or just under 3 GB per week. With a buffer for the unexpected, a 5 GB plan has you covered. If you also watch an hour of Reels on mobile data every evening, add another 4–6 GB, and a 10 GB plan is the better choice.

Hotspot and laptop: the hidden data hog

Sharing data with your laptop via hotspot pushes usage up fast. Computers download system updates in the background, sync cloud folders and load full desktop websites. An hour-long video meeting uses 0.5–1.5 GB depending on quality. Before connecting, set the hotspot as a metered connection on Windows, or pause cloud sync and updates on macOS. For remote work, choose a large plan or one that explicitly allows hotspot use.

For a resort vacation in Mexico or Turkey with good hotel Wi-Fi, a small plan is often enough. On a tour through Thailand or Japan with lots of navigation and app-based ticket bookings, plan more generously. On a road trip across the USA, a bigger plan also pays off, because navigation and music streaming run for hours.

Unlimited or fixed GB?

Fixed data plans are usually cheaper and almost always allow hotspot use. If you can roughly estimate your usage, they are the best choice. Unlimited plans offer peace of mind but often have a daily fair use limit, after which speed drops sharply. For heavy users and long trips they can still work out cheaper. In our comparison, every unlimited plan shows its throttling limit.

How to save data

• Offline maps: download the area in Google Maps or Maps.me ahead of time. Navigation then uses almost no data.
• Automatic updates and backups on Wi-Fi only (App Store, iCloud, Google Photos).
• Turn off autoplay in Instagram, Facebook and YouTube, or use the app's data saver.
• Download music and shows for offline use before you go.
• Turn on your phone's data saver (iPhone: Cellular → Data Options → Low Data Mode; Android: Data Saver).
• Check usage: your cellular settings show which apps use the most data.

Traveling as a couple or family

When several people travel together, there are two options: everyone gets their own eSIM, or one person buys a large plan and shares it via hotspot. Separate eSIMs are more flexible, since everyone can go their own way and nobody drains one phone's battery. A shared plan can be cheaper if you are together most of the time, for example on a road trip. When sharing, add up the needs of all devices and plan generously: kids with tablets and videos often use more than you expect. Also check that the plan allows hotspot use.

Bought too little? No problem

Most providers let you top up right in the app, without a new eSIM. When in doubt, start with a mid-size plan and add more if needed. When comparing, check whether the provider supports top-ups; our provider overview lists it. Our guides for iPhone and Android help with setup.
