How much data do I need for a week abroad?

A normal traveler using maps, messaging, socials and the occasional video needs roughly 500MB–1GB per day, so about 3–5GB for a week. Light users can do 3GB; heavy streamers should plan on 1–2GB per day or an unlimited plan.

Does Google Maps use a lot of data?

No — turn-by-turn navigation uses only about 3–5MB per hour. Downloading offline maps once saves even that. Maps is one of the cheapest things you'll do on your data.

What uses the most data while traveling?

Video is by far the biggest: streaming or watching Instagram/TikTok reels can burn 1GB or more per hour on HD. Video calls are next (about 300–500MB per hour). Maps, messaging and web browsing are tiny by comparison.

How Much eSIM Data Do I Need for Travel? (2026 Data Calculator & Guide)

The short answer

Light

~300MB/day

Maps, WhatsApp, boarding passes, a few photos uploaded. Mostly on Wi-Fi at the hotel.

Normal

~700MB/day

Maps all day, socials, messaging, the odd video and video call home. The typical traveler.

Heavy

1.5GB+/day

Streaming, daily Reels/TikTok, long video calls, hotspotting a laptop. Consider unlimited.

👉 Rule of thumb: most travelers are comfortable on 1GB per day, so a one-week trip lands around 5GB. Start there; you can always top up in-app in seconds if you run low.

What actually uses your data

Data anxiety usually blames the wrong things. Maps barely sip; video gulps. Rough hourly costs:

Activity	Rough data cost	Reality
Google Maps navigation	~3–5 MB / hour	Basically free. Download offline maps and it's near zero.
WhatsApp / iMessage texts	< 1 MB / hour	Negligible. Voice notes add a little.
Web & email	~10–20 MB / hour	Light. Checking bookings, reviews, translation.
Instagram / TikTok scrolling	~500 MB – 1 GB / hour	The silent budget killer. Reels are video.
Video call (WhatsApp / FaceTime)	~300–500 MB / hour	Fine in short bursts; a daily hour adds up over a trip.
HD video streaming	~1–2 GB / hour	The biggest single cost. Save it for Wi-Fi if you can.

Plan size by trip length

Using the ~1GB/day rule for a normal traveler:

Trip length	Light user	Normal user	Heavy user
Weekend (3 days)	1 GB	3 GB	5 GB+
One week	3 GB	5 GB	10 GB / unlimited
Two weeks	5 GB	10 GB	20 GB / unlimited
One month	10 GB	20 GB	unlimited

Hotspotting a laptop, or one person's plan shared across the family, pushes you up a column. When in doubt, buy a bit less and top up in-app — cheaper than overbuying.

Don't overbuy — top up instead

The most common mistake is buying a giant plan "just in case" and coming home with 15GB unused. With Beaver you can start with a smaller plan and top up inside the app in seconds if you run low — so you only pay for what you actually use. Beaver country plans start at $0.99, and a normal week runs just a few dollars.

Frequently asked

Is it better to buy a big plan or top up?

Top up. Buying a smaller plan and adding data in-app if you run low means you never pay for gigabytes you don't use — and topping up takes seconds, no hunting for Wi-Fi.

Does streaming Netflix abroad use my eSIM data?

Yes, and it's the most expensive thing you can do — HD streaming burns 1–2GB per hour. Download shows over hotel Wi-Fi before you head out for the day.

How much data does a week in Japan need?

For a normal traveler: about 5GB. Maps, translation, socials and messaging are light; the number climbs only if you stream video or hotspot a laptop daily.

What happens if I run out of data?

With Beaver you top up directly in the app in a few taps — no need to buy a whole new plan or find Wi-Fi. Your same eSIM keeps working.
