How much data do you need for a trip abroad?
In short: for light use 1–3 GB a week is enough, for moderate use you need 3–7 GB, and for streaming, video calls or hotspot count on 7–15 GB or more. Choose according to how you use your smartphone on the road — and remember you can always buy an extra plan if you run out of data.

| Google Maps / navigation | ~3–5 MB an hour (very little) |
| Instagram / social media | ~100 MB an hour (up to ~700 MB with reels) |
| Video streaming (SD) | ~0.7–1 GB an hour (much more in HD) |

Tip: always add a small margin and download maps and playlists offline on Wi-Fi before you leave.
Frequently asked questions about data usage
For light use (maps, messages, searches) 1–3 GB a week is enough. For moderate use with social media and music allow 3–7 GB. If you watch video, make video calls or use the hotspot, count on 7–15 GB or more. If in doubt, choose a slightly bigger plan: you can always buy another one if you run out of data.
Double the weekly estimate for your profile: about 2–6 GB for light use, 6–14 GB for moderate use and 15–30 GB for heavy use. Remember that downloading maps and playlists offline on Wi-Fi cuts consumption a lot.
Text messages use very little: with 1 GB you can send over 200,000 messages. Voice calls use about 0.5 MB a minute, video calls 5–7 MB a minute. WhatsApp is therefore very light, unless you make long video calls every day.
1 GB covers about a week of light use: maps to find your way, messages, a few searches and a few photos. A little video streaming, though, can use it up in a couple of hours. If you watch video on the move, aim for at least 5–10 GB.
Very little: navigation uses about 3–5 MB an hour. You can cut usage further by downloading offline maps on Wi-Fi before you leave. Maps are never the biggest drain on your data during a trip.
