Quick answer
Data usage by traveler type.
Find your usage profile below. These estimates assume you use WiFi at your accommodation each evening and do not stream video over cellular.
Light
300–500 MBActivities: Maps, messaging, email
Sightseers who use hotel WiFi for streaming
Moderate
1–2 GBActivities: Social media, browsing, video calls (occasional)
Most leisure travelers
Heavy
2–3 GBActivities: Regular video calls, Instagram Stories, YouTube
Content creators, frequent communicators
Remote work
3–5 GBActivities: Cloud apps, video meetings, file uploads
Digital nomads, business travelers
By activity
Data usage per app and activity.
These figures are measured averages. Actual usage varies by app version, video quality settings, and network conditions.
| Activity | Data usage |
|---|---|
| Google Maps (navigation) | 5–10 MB/hr |
| WhatsApp / iMessage text | 1–5 MB/hr |
| WhatsApp voice call | 3–5 MB/min |
| Instagram (scrolling) | 150–300 MB/hr |
| TikTok (scrolling) | 500 MB–1 GB/hr |
| Video call (FaceTime/Zoom) | 500 MB–1.5 GB/hr |
| YouTube SD (480p) | ~350 MB/hr |
| YouTube HD (1080p) | ~3 GB/hr |
| Spotify / Apple Music | 40–150 MB/hr |
| Email with attachments | 50–100 MB/hr |
| Web browsing | 50–100 MB/hr |
Calculator
How to calculate your plan size.
Use this three-step method to arrive at a number before you browse plans.
Step 1: Start with your daily estimate
Pick your usage tier from the table above. Use the midpoint of the range. Light user: 400 MB/day. Moderate: 1.5 GB/day. Heavy: 2.5 GB/day. Remote work: 4 GB/day.
Step 2: Multiply by trip length
| Trip | Light (400 MB/day) | Moderate (1.5 GB/day) | Heavy (2.5 GB/day) |
|---|---|---|---|
| 3 days | 1.2 GB | 4.5 GB | 7.5 GB |
| 7 days | 2.8 GB | 10.5 GB | 17.5 GB |
| 14 days | 5.6 GB | 21 GB | 35 GB |
Step 3: Apply a WiFi offset
If your accommodation has reliable WiFi, reduce your total by 30–40%. Hotel WiFi handles evening streaming, morning email, and video calls, which are the heaviest data activities. If WiFi is unreliable or you are camping or on a road trip, use the full figure with no reduction.
Then round up to the next available plan size. Never round down.

Avoid if: Long-stay remote workers who need more than 1 GB/day consistently
Remote workers, long stays, or travelers who stream daily
Covers: Everything — subject to daily fair-use throttle (usually 1–2 GB/day at full speed)
Avoid if: Short trips under 7 days where a fixed plan is cheaper per GB
Save data
Tips to use less data on your trip.
Download offline maps
Google Maps and Apple Maps let you download a country or city map before you leave. Navigation uses zero data once the map is cached.
Enable data saver mode
iPhone: Settings > Cellular > [travel line] > Low Data Mode. Android: Settings > Network > Data Saver. Reduces background app data by 50–70%.
Use WiFi calling
Enable WiFi calling on your home SIM line for calls and texts over hotel WiFi. This removes voice traffic from your travel eSIM data allowance entirely.
Download before you fly
Spotify playlists, Netflix downloads, and Kindle books take zero travel data when loaded at home. Fill your device before boarding.
Lower video quality
Switch YouTube to 360p and Zoom to 360p video. This cuts video call data use by 60–70% with almost no visible quality loss on a phone screen.
Turn off background app refresh
iPhone: Settings > General > Background App Refresh > Off. Android: Settings > Apps > [App] > Battery > Restricted. Stops apps from quietly consuming data in the background.
FAQ
Data planning questions.
Is 1 GB enough for a week abroad?
Only if you use WiFi most of the time. 1 GB covers about 2 days of light use: messaging, maps, and quick browsing. For a 7-day trip with regular phone use, a 3 GB or 5 GB plan is a safer choice.
Does an eSIM data plan expire?
Yes. Most plans have a validity window of 7, 15, or 30 days from the date of first activation, not from purchase. Some providers start the clock on installation. Check your plan terms before you buy.
Should I buy unlimited or a fixed data plan?
Fixed plans are usually better value for trips under 14 days. Unlimited plans make sense for remote work travel or long stays where you stream video daily. Unlimited plans often throttle speeds after 1-2 GB per day.
What happens when I run out of data?
Depending on your provider and plan, your connection either stops completely or throttles to a very slow speed (usually 128-256 kbps). Most providers let you top up additional data through their app without reinstalling the eSIM.
How can I monitor my data usage while traveling?
iPhone: Settings > Cellular > [travel eSIM line] shows data used. Android: Settings > Network > SIMs > Data usage. Most eSIM provider apps also show real-time usage. Reset the counter at the start of your trip for an accurate reading.
