How long 1 GB of data lasts when you're travelling
A gigabyte goes a long way or lasts twenty minutes, and the only difference is video. What fits inside one, and when it falls short.

What fits in 1 GB
Each row is what a whole gigabyte would stretch to if you spent it on that alone. The figures are approximate, but the order of magnitude is what matters.
| With 1 GB you can | How much |
|---|---|
| Navigate with Google Maps | about 150 hours |
| Send text messages | effectively without limit |
| Talk on WhatsApp | about 35 hours |
| Browse web pages | about 500 pages |
| Stream music | about 15 hours |
| Watch stories on social media | about 4 hours |
| Watch reels or TikTok | 1 to 2 hours |
| Video calls | about 4 hours |
| Watch HD video | about 40 minutes |
The list reads itself: as long as there's no video, a gigabyte is enormous. The moment video appears, it evaporates.
Is 1 GB enough for a trip?
For a weekend with wifi at the hotel and moderate use, yes: maps, messaging, the odd search and photos uploaded in the evening from your room fit comfortably.
For a week it's tight unless you barely touch your phone. And for any trip where you'll check social media out of habit, a gigabyte is gone in two or three days.
| Trip | Is 1 GB enough |
|---|---|
| Weekend, minimal use, hotel with wifi | Yes |
| Normal weekend with social media | Just about |
| A week with maps and messaging | No, reckon on 2 to 3 GB |
| A week posting daily | No, reckon on 5 GB or more |
How to stretch a gigabyte
- Download the city maps before you leave, on wifi.
- Set photo backup to wifi only. It's the one that slips through unasked most often.
- Switch on your system's data saver, which holds back background activity from apps you aren't using.
- Turn off video autoplay on any social app that lets you.
- Download music, series and podcasts before you travel. Flights and transfers are where they get used most.
With those five things done, the same gigabyte can last twice as long as it would without them.
And a comparison that helps you decide
At home, an average phone uses considerably more than a gigabyte a week, and that's with wifi for much of the day. Travelling, that wifi disappears for hours at a time and maps appear, so usage goes up. One gigabyte per week of travel is an optimistic estimate for almost everybody.
The precise sums, by type of traveller and destination, are in how much data you actually use on a trip.
Frequently asked questions
How long does 1 GB of data last?
It depends entirely on video. It stretches to about 150 hours of Google Maps or 35 hours of WhatsApp calls, but only one or two hours of reels and around 40 minutes of HD video.
Is 1 GB enough for a week away?
Only with very light use and wifi where you're staying. For a normal week with maps and messaging, reckon on 2 to 3 GB.
How many photos can I upload with 1 GB?
Between 300 and 400 phone photos compressed by messaging apps, or roughly 100 to 200 at high quality.
How much video can I watch with 1 GB?
About 40 minutes in HD, around two hours at standard quality, and a bit more if you lower the quality manually in the app.
How do I make a gigabyte last longer?
Download maps on wifi, set backups to wifi only, switch on your system's data saver and turn off video autoplay.
