How much mobile data do you need for a two-week holiday?
For a typical two-week holiday, most travellers get by comfortably on somewhere between 5 GB and 10 GB of mobile data, assuming they use Wi-Fi at their accommodation for the heaviest tasks. Light users can manage on less, while anyone streaming video or working on the road will want more. The right number depends almost entirely on what you do online while you are away.
This guide gives you a quick estimate, shows what actually eats into an allowance, and offers a few simple habits to make your data last. If you are still choosing how to get connected, our explainer on what an eSIM is is a good starting point.
A quick answer
If you mostly use maps, messaging, and a bit of social media, and you connect to Wi-Fi each evening, plan for roughly 5 GB to 10 GB across a fortnight. Treat that as a starting point and adjust up if you stream a lot of video or rely on data for work. It is usually easier to choose a slightly larger allowance than to run dry halfway through the trip.
What uses the most data when travelling
Not all activities are equal. From lightest to heaviest, a rough hierarchy looks like this:
- Very light: messaging, email, and looking up directions use very little data.
- Light to moderate: live navigation, web browsing, and scrolling social feeds without autoplay video.
- Moderate: photo backups and social media with video playing.
- Heavy: streaming music for hours, video calls, and watching shows or films.
- Very heavy: streaming high-definition video and downloading large files over mobile data.
The single biggest swing is video. An hour of streaming can use more than a whole day of maps and messaging combined, so it is the first thing to move onto Wi-Fi.
Data estimates by traveller type
Use these rough two-week guides to pick an allowance. They assume you use Wi-Fi at your accommodation for big downloads and backups.
| Traveller type | Typical habits | Rough two-week need |
|---|---|---|
| Light | Maps, messaging, occasional browsing | 2 GB to 4 GB |
| Moderate | The above plus social media and photo sharing | 5 GB to 10 GB |
| Heavy | Frequent social video, some streaming, hotspot use | 12 GB to 20 GB |
| Working remotely | Video calls, uploads, and tethering a laptop | 20 GB or more |
If you fall between two rows, round up. Many travel plans let you top up partway through, but it is more relaxing to start with enough.
How to make your data go further
A few small habits stretch an allowance a long way:
- Download before you go. Save offline maps, playlists, and any shows for the journey while you are on Wi-Fi at home or your hotel.
- Use Wi-Fi for the heavy jobs. Back up photos and run big updates on a trusted network rather than over mobile data.
- Turn off autoplay video in your social apps so feeds stop burning data in the background.
- Watch background app refresh. Stop apps you are not using from updating over mobile data in your phone's settings.
- Stream audio, not video, when you only need the sound, and drop the quality a notch when you do stream.

Choosing a plan size
Once you have a sense of your daily habits, picking a plan is straightforward: estimate your light, moderate, or heavy profile, match it to the table above, and choose the next size up if you are unsure. A travel eSIM makes this easy, because you select an allowance before you fly and switch it on when you land, with no shop visit needed. Saily offers a range of plan sizes across many destinations, so you can match the data to your trip rather than guessing at the airport.

Frequently asked questions
How much data does a two-week holiday really need? Most travellers are comfortable with 5 GB to 10 GB if they use Wi-Fi for big tasks. Light users need less, and heavy streamers or remote workers need considerably more.
Is 5 GB enough for two weeks abroad? For a light to moderate user who mostly relies on maps, messaging, and some social media, 5 GB is often enough, especially with Wi-Fi in the evenings. If you stream video on the go, plan for more.
What uses the most mobile data when travelling? Streaming video is by far the heaviest, followed by video calls and large downloads. Maps and messaging use very little by comparison.
Does using maps abroad use a lot of data? Live navigation is fairly light, and downloading offline maps over Wi-Fi first reduces it further. It is rarely the reason an allowance runs out.
Can I add more data partway through my trip? Usually yes. Many travel data plans let you top up or buy an additional allowance, though it is more relaxing to start with a comfortable amount.
How can I reduce my data use abroad? Download maps and media before you go, lean on trusted Wi-Fi for heavy tasks, turn off video autoplay, and limit background app refresh.
Should I stream video on mobile data while travelling? It is best saved for Wi-Fi, as it is the quickest way to drain an allowance. If you must stream on data, lower the quality setting.
How is a travel eSIM different from roaming for data? With a travel eSIM you choose your destination and allowance in advance and install it before you fly. Roaming uses your home plan, with terms that vary by provider. Our guide on eSIM vs SIM card explains more.
Do video calls use much data? Yes, video calls are among the heavier activities. Where you can, make them over Wi-Fi from your accommodation rather than on mobile data.
What if I am working remotely on my trip? Remote work, especially video meetings and file uploads, can use 20 GB or more across two weeks. Choose a generous plan and use Wi-Fi wherever it is reliable.
