How much eSIM data do you need for your trip?

Buying a travel eSIM is easy once you know roughly how much data you'll use. Most travelers overestimate. If you're mainly using maps, messaging, and a bit of browsing on Wi-Fi in the evenings, a little goes a long way. Here's how to estimate the right plan size so you don't overpay or run out.

A quick rule of thumb

For light use (maps, chat, email) budget around 300–500 MB per day. For normal use (add social media and web browsing) plan for about 1 GB per day. For heavy use (lots of video, streaming, hotspot) 2 GB or more per day is safer. Multiply by your trip length and round up a little.

Data by activity (rough guide)

Maps and navigation: about 5 MB per hour.
Messaging and email: a few MB per day.
Social media scrolling: roughly 100–150 MB per hour.
Music streaming: about 60–100 MB per hour.
Video streaming (SD): around 500 MB–1 GB per hour.

Putting it together

Say you're away for a week and use data for maps, messaging, and some social media, mostly connecting to Wi-Fi at your hotel. Around 1 GB per day — about 7 GB total — is comfortable. Prefer to stream video on the go or tether a laptop? Step up to a larger plan or plan to top up.

Ways to use less

Download maps, playlists, and shows over Wi-Fi before you head out.
Use Wi-Fi at your accommodation for big downloads and backups.
Set streaming apps to a lower quality and turn off video autoplay.

Frequently asked questions

How much data do I need for a week abroad?

For typical use — maps, messaging, some browsing and social — about 1 GB per day, so roughly 5–7 GB for a week. Heavy video or hotspot use needs more.

What happens if I run out of data?

You simply top up your alodata eSIM or add another plan — no need to reinstall. It's smart to top up before you hit zero so you stay connected without a gap.

Is unlimited data worth it?

Only if you stream or tether a lot. Most travelers comfortably stay within a few GB per week, so a right-sized plan is usually better value than unlimited.
