The Short Answer
For most holidaymakers, 500MB per day covers maps, social media, and music streaming comfortably. That means a one-week trip needs roughly 3.5GB, and a two-week holiday around 7GB. Fuse Mobile's Pulse plan (10GB) handles the majority of one- and two-week trips for moderate users, while the Surge plan (15GB) gives heavier users or longer travellers plenty of breathing room — and crucially, both plans include roaming in 130+ countries at no extra cost, so your full monthly allowance works abroad exactly as it does at home.
Why Data Estimates Matter More When You're Abroad
At home, you probably don't think twice about data. You're near Wi-Fi most of the time, and if you run low, topping up is easy. Abroad, the calculation changes. Hotel Wi-Fi can be patchy, you're using maps constantly, and you're reaching for your phone more than usual — checking restaurant reviews, translating menus, sharing photos.
The bigger trap used to be roaming charges. Many providers either block roaming entirely or hit you with daily fees that quietly stack up. Fuse works differently: on Pulse and Surge plans, your data allowance is the same whether you're in London or Lisbon. There's no separate roaming pool, no daily bolt-on, and no bill shock at the end of the month.
So the real question isn't "will roaming cost me extra?" — it's simply "how much data do I actually use?"
How Much Data Does Each Activity Actually Use?
Let's break it down by the things you're most likely to do on holiday.
Navigation (Google Maps)
Google Maps uses roughly 5MB per hour when you're actively navigating. If you're driving or walking with turn-by-turn directions for two hours a day, that's about 10MB — barely a dent. Downloading offline maps before you leave is still a good habit (it saves data and works without signal), but even if you forget, navigation won't be what drains your allowance.
Music Streaming (Spotify)
Spotify's data usage depends on your quality setting:
- Normal quality: ~40MB/hour
- High quality: ~70MB/hour
- Very high quality: ~150MB/hour
If you stream music for two hours a day at normal quality, that's around 80MB. Switch to very high quality and it climbs to 300MB. Downloading playlists over Wi-Fi before you travel is the easiest way to sidestep this entirely.
Social Media (Instagram, TikTok, Threads)
Scrolling Instagram — photos, Reels, Stories — uses roughly 100MB per hour. TikTok runs higher, closer to 150–200MB per hour if you're watching a lot of video. Even at a modest 30 minutes of Instagram browsing a day, you're looking at 50MB. An hour of mixed social media browsing sits around 100–150MB.
Video Calls (FaceTime, WhatsApp, Zoom)
This is the big one. Video calls consume roughly 600MB per hour — around 10MB per minute. A 10-minute catch-up call uses about 100MB. If you're working remotely or calling family every evening, this adds up fast. Audio-only calls are far more efficient at around 3–5MB per minute.
Messaging (WhatsApp, iMessage, SMS)
Text messages and voice notes use almost nothing — well under 5MB per day for typical usage. Even sending a few photos over WhatsApp each day won't move the needle significantly.
Web Browsing and Maps
Casual browsing — checking a restaurant's menu, reading a review, looking something up — uses around 10–20MB per hour. It's background noise compared to streaming.
Your Daily Data Budget: Three Traveller Profiles
Here's how those activities add up across three realistic usage patterns.
| Usage Profile | Typical Activities | Est. Daily Data | 7-Day Trip | 14-Day Trip |
|---|---|---|---|---|
| Light user | Maps + messaging + light browsing | ~100MB/day | ~700MB | ~1.4GB |
| Moderate user | Maps + social media + music streaming | ~500MB/day | ~3.5GB | ~7GB |
| Heavy user | Video calls + streaming + social media | ~1GB+/day | ~7GB+ | ~14GB+ |
Light User (~100MB/day)
You use your phone for navigation and the occasional message. You're not on social media much, you've downloaded your music offline, and you're not video calling. A week away uses under 1GB. Even a fortnight is well within 2GB. Honestly, the Pulse plan's 10GB is more than you'd ever need.
Four UK networks, one eSIM. No contract.
Get connected to all four UK networks and never worry about signal again.
Moderate User (~500MB/day)
This is most travellers. You're navigating, scrolling Instagram for 30–45 minutes, streaming some music, and sending photos to friends. Maybe a short video call every couple of days. At 500MB/day, a one-week holiday uses about 3.5GB and a two-week holiday around 7GB — both comfortably within the Pulse plan's 10GB.
Heavy User (~1GB+/day)
You're working remotely, video calling family daily, streaming podcasts or music at high quality, and posting to social media regularly. At 1GB per day, a one-week trip uses 7GB and a two-week trip pushes past 14GB. The Surge plan's 15GB covers most two-week heavy-use trips, though if you're genuinely working abroad for a month, you'd want to plan accordingly.
Mapping This to Fuse Plans
Fuse offers three plans, but only two include roaming: Pulse (10GB, £9.99/mo) and Surge (15GB, £14.99/mo). The Spark plan (5GB, £5.99/mo) is UK-only.
Pulse (10GB) suits:
- Light users on any length trip
- Moderate users on trips up to two weeks
- Anyone who uses Wi-Fi regularly at their hotel or apartment
Surge (15GB) suits:
- Heavy users on trips of a week or more
- Moderate users on longer trips (3+ weeks)
- Anyone working remotely or video calling daily
- Travellers who prefer the peace of mind of extra headroom
Both plans work identically at home and abroad — your 10GB or 15GB is one pool, not split between "UK data" and "roaming data". When you land, your phone connects automatically to a local partner network. There's no activation step, no daily fee, and nothing to configure. You can read more about how it works on the Fuse roaming page.
Practical Tips to Make Your Data Go Further
Even if you've picked the right plan, a few habits can stretch your allowance further.
Download before you go. Spotify playlists, Google Maps offline areas, and Netflix downloads (if your accommodation has Wi-Fi) can dramatically cut your daily usage.
Set apps to lower quality. Dropping Spotify from "Very High" to "Normal" cuts streaming data by 75%. Most people can't hear the difference through phone speakers.
Switch video calls to audio when you don't need the camera. A 20-minute audio call uses about 100MB. The same call on video uses over 200MB.
Use Wi-Fi for large uploads. Backing up holiday photos or uploading long videos to social media is best done over hotel Wi-Fi rather than mobile data.
Check your background app refresh settings. Some apps — particularly social media — refresh in the background constantly. Turning this off for data-hungry apps can save 50–100MB per day without you noticing.
A Note on Roaming Coverage
Data allowance is only useful if you actually have a signal. Fuse connects to all four UK networks — EE, Three, Vodafone, and O2 — and automatically switches to the strongest signal wherever you are. Abroad, your phone connects to a local partner network in 130+ countries. You can check destination-specific coverage on the Fuse roaming page before you travel.

Summary
Working out how much data you need abroad doesn't have to be complicated. Start with your profile — light, moderate, or heavy — multiply your daily estimate by your trip length, and add a buffer. For most people on a one- or two-week holiday, 10GB is plenty. If you're a heavy user or travelling for longer, 15GB gives you the headroom to use your phone without constantly watching the counter.
With Fuse, both Pulse and Surge include roaming in 130+ countries as standard — no daily fees, no roaming add-ons, just your normal allowance working wherever you are. Compare plans and get started.
Frequently Asked Questions
How much mobile data do I need for a one-week holiday?
For a moderate user — maps, social media, and some music streaming — budget around 500MB per day, which comes to roughly 3.5GB for a week. A 10GB plan gives you comfortable headroom for a one-week trip even if you use your phone more than expected.
Does roaming use a separate data allowance with Fuse?
No. On Fuse's Pulse and Surge plans, roaming in 130+ countries uses your normal monthly data allowance. There's no separate roaming pool and no daily roaming fee — your 10GB or 15GB works the same whether you're in the UK or abroad.
Is 10GB enough for two weeks abroad?
For most moderate users, yes. At 500MB per day, a 14-day holiday uses around 7GB, leaving a 3GB buffer on the Pulse plan. If you're a heavy user — video calls, high-quality streaming, lots of social media — consider the Surge plan's 15GB for a two-week trip.
What uses the most mobile data on holiday?
Video calls are the biggest drain at roughly 600MB per hour. After that, video streaming and TikTok browsing are the next most data-intensive. Navigation, messaging, and basic web browsing use comparatively very little.
Which Fuse plan includes roaming?
Roaming in 130+ countries is included on the Pulse (10GB, £9.99/mo) and Surge (15GB, £14.99/mo) plans. The Spark plan (5GB, £5.99/mo) is UK-only and does not include roaming. See the full plan comparison for details.
