How Much Mobile Data Do You Actually Use When Travelling?

A realistic, activity-by-activity estimate — plus how to measure your own usage and cut it down

Disclosure: this article is written by the NXTL team. NXTL makes a travel eSIM, which we mention briefly below.

"How many gigabytes do I need for two weeks in Spain?" is one of the most common travel questions, and the honest answer is: it depends almost entirely on what you do with your phone. A traveller who navigates and messages might get by on a few hundred megabytes a week. One who uploads Stories and takes video calls every evening can burn through several gigabytes.

Below is a breakdown by activity. All figures are rough estimates. Real usage varies with app versions, video quality settings, network speed, and how much of your phone's background activity you allow. Treat these as planning ranges, not guarantees.

Rough data use by activity

Maps and navigation

• Live navigation (Google Maps, Apple Maps): roughly 2–10 MB per hour of active driving or walking directions.
• Browsing a map, searching places, loading photos and reviews: can be higher, around 10–30 MB per hour of heavy exploring, because place photos are the expensive part.
• Offline maps: close to zero once downloaded (download them on Wi-Fi beforehand).

Navigation is far cheaper than most people fear. It is rarely what drains a travel data budget.

Messaging

• Text-only chats (WhatsApp, Telegram, iMessage, Signal): a few KB per message — often under 1–5 MB a day even for chatty users.
• Photos: roughly 0.1–0.5 MB each after app compression; more if you send "HD" or original quality.
• Voice notes: roughly 0.5–1 MB per minute.
• Videos sent in chats: anywhere from 2 MB to 50+ MB per clip.

Group chats full of forwarded videos are a hidden cost. Auto-download is usually the culprit (more on that below).

Social media

• Scrolling Instagram, TikTok, or Facebook: roughly 300 MB–1 GB+ per hour. Short-form video feeds are the heaviest because videos autoplay and preload.
• Posting a photo: a few MB.
• Posting a Story or Reel: roughly 10–50 MB per upload, depending on length and quality.

If you only change one habit while abroad, make it this one: scroll on Wi-Fi, post on mobile data.

Music and podcasts

• Music streaming: roughly 40–150 MB per hour depending on quality setting.
• Podcasts: roughly 30–60 MB per hour-long episode.
• Downloaded playlists and episodes: near zero while travelling.

Video streaming

• Standard definition (480p): roughly 0.5–1 GB per hour.
• HD (720p–1080p): roughly 1.5–3 GB per hour.
• 4K: 5–7 GB+ per hour — rarely worth it on a phone screen.

A single HD movie can cost more data than a week of navigation and messaging combined.

Video calls

• Audio-only internet calls (WhatsApp, FaceTime Audio, etc.): roughly 0.5–1.5 MB per minute, or about 30–90 MB per hour.
• Video calls (FaceTime, Zoom, Google Meet, WhatsApp video): roughly 300 MB–1.5 GB per hour, depending on resolution and the number of participants.

Group video calls on Zoom or Meet sit at the top of that range.

Hotspotting a laptop

This is where estimates break down, because a laptop behaves very differently from a phone:

• Light work (email, docs, chat): roughly 100–300 MB per hour.
• Cloud sync, OS updates, or app updates in the background: can quietly consume several GB in one session.
• Video meetings from the laptop: similar to video calls above, often at the higher end.

Before tethering, pause cloud sync (Dropbox, iCloud, OneDrive, Google Drive) and mark the connection as metered so Windows or macOS doesn't start large downloads.

A few sample trip profiles (rough estimates)

Traveller type	Typical daily use	One week
Light: maps, messaging, occasional browsing	50–150 MB	0.4–1 GB
Moderate: plus social posting and some music	200–500 MB	1.5–3.5 GB
Heavy: plus video calls, scrolling, some streaming	1–3 GB	7–20 GB
Working remotely via hotspot	2–5 GB+	15–35 GB+

For more detail on how travellers actually use data, NXTL published a travel eSIM usage study with its methodology.

How to measure your own usage before you go

The best estimate is your own history. Check it a week or two before you travel.

On iPhone: go to Settings → Cellular (or Mobile Data). You'll see "Current Period" usage and a per-app list. Scroll to the bottom to find Reset Statistics — reset it at the start of a normal week, then check after seven days. Note that iPhone doesn't reset this counter automatically.

On Android: go to Settings → Network & internet → SIMs (or Mobile network) → App data usage. Menu names vary by manufacturer; on Samsung it's Settings → Connections → Data usage → Mobile data usage. You can set the date range to match a week and see which apps use the most.

Then adjust: if most of your home usage is streaming you won't do abroad, subtract it; if you'll rely on mobile data instead of home Wi-Fi, add more.

How to cut usage without missing out

1. Download offline maps for each city before leaving.
2. Turn off auto-download for photos and videos in WhatsApp, Telegram, and other messengers.
3. Lower streaming quality in Netflix, YouTube, and Spotify settings, or download content on hotel Wi-Fi.
4. Disable background app refresh for apps you don't need (iPhone: Settings → General → Background App Refresh; Android: per-app "Background data" toggle or Data Saver).
5. Turn off autoplay in social apps; Instagram and Facebook both have data-saver options.
6. Stop automatic app and OS updates over mobile data.
7. Pause photo backup (iCloud Photos, Google Photos) until you're on Wi-Fi.
8. Watch for "Wi-Fi Assist" / adaptive Wi-Fi, which can switch to mobile data when hotel Wi-Fi is weak.

Choosing a plan that matches your estimate

Once you have a realistic number, the plan type matters. Fixed bundles suit travellers who know their usage well. If your estimate is uncertain — say, somewhere between 1 and 5 GB — a pay-as-you-go option lets you pay only for what you use.

NXTL's Global eSIM is one such option: a data-only, prepaid-balance eSIM where usage is charged proportionally in 1 KB increments at the published rate for the network you're on. On the web, the starter is US$11.99, which includes US$10 of usable balance plus US$1.99 for the eSIM (in-app prices may differ). Per-GB rates vary widely by country and network, so check the current rates on the pricing page for your destination before you estimate costs.

Whatever you choose, measure first, cut the obvious waste, and budget a little headroom. The traveller who runs out of data is usually not the one who navigated too much — it's the one whose phone backed up 400 photos over mobile data on day one.
