Frequently asked questions
How much mobile data do I use per day when traveling?
About 1.1 GB a day for an everyday traveler on cellular data. A light user on maps and messaging uses about 0.3 GB, and a remote worker with video calls and HD streaming about 2.7 GB. These come from typical per-hour rates for each activity, and time on Wi-Fi does not count.
Is 1 GB per day enough for travel?
For light and many average users, yes, though an everyday traveler comes out at about 1.1 GB, so it is borderline. It covers all-day maps, messaging and a fair amount of social media. It runs short if you stream HD video or take video calls daily, and then you should budget 2.7 GB or more.
How long will 5 GB last on a trip?
On cellular alone, about 4.7 days for an average user, 17 days for a light user, and 1.8 days for a heavy user. See the table above for other plan sizes.
What uses the most data on holiday?
Video. HD streaming is about 1.1 GB an hour, video calls about 600 MB, and social media about 500 MB an hour because of auto-playing video. Maps, at about 8 MB an hour, and messaging, at about 3 MB an hour, are almost free by comparison.
Does using my phone as a hotspot use more data?
Usually, yes. A laptop tends to use much more than a phone because it downloads updates, syncs files and loads full desktop pages. If you will tether, size your plan up and check that the plan allows hotspot. Our hotspot guide covers the details.
Should I pick a fixed-GB plan or unlimited?
Unlimited plans give you 1 GB a day at full speed, then 512 kbps. That fits an average user well and suits heavy or unpredictable use. If you are mostly on maps and messaging, a fixed plan is cheaper.
How can I use less data abroad?
Download offline maps and playlists on hotel Wi-Fi, set app updates and cloud photo backup to Wi-Fi only, turn off video auto-play in social apps, and lower streaming quality. Video is where nearly all your data goes, so that is where the savings are.
Do voice calls over WhatsApp or FaceTime use a lot of data?
Voice-only calls use far less than video calls, which run at around 600 MB an hour in our model. Video is what makes calls expensive in data.
What happens when my data runs out?
The eSIM stops passing data. There are no overage charges. You can buy a top-up or a new eSIM at any time, so if your estimate is close to a plan size, choose the larger one.
