Roaming Streaming Abroad: How Much Data You Really Need

You're on the train to Munich, you want to watch a Netflix series – and suddenly your roaming data volume is used up. Anyone who travels abroad regularly and uses streaming services knows this problem. This guide shows you how much data Netflix, Disney+, YouTube and others actually consume, what EU roaming means for Swiss people and how you can significantly reduce your data usage with a few simple measures.

Overview of Data Consumption for the Biggest Streaming Services

Data consumption depends primarily on the video quality selected. Here are the realistic values you can expect when streaming on mobile while travelling:

Netflix

Netflix provides the following reference values:

• SD (Standard Definition): approx. 0.3 GB per hour
• HD (720p/1080p): approx. 1 GB (720p) to 3 GB (1080p) per hour
• 4K Ultra HD: up to 7 GB per hour

By default, the Netflix app automatically adjusts the quality to the available connection. On a mobile device, this usually results in HD – i.e. around 1 to 3 GB per hour.

Disney+

Disney+ behaves similarly to Netflix:

• SD: approx. 0.7 GB per hour
• HD: approx. 2 GB per hour
• 4K HDR: up to 8 GB per hour

YouTube

YouTube is more flexible to configure:

• 360p: approx. 0.13 GB per hour
• 480p: approx. 0.26 GB per hour
• 720p (HD): approx. 0.9 GB per hour
• 1080p (Full HD): approx. 1.5 GB per hour

Spotify and Podcasts

Audio streaming is significantly more data-efficient: Spotify at the highest quality level (320 kbps) consumes around 0.14 GB per hour – barely worth mentioning.

What EU Roaming Means for Swiss People

Switzerland is not an EU member – this has a direct impact on your roaming experience. The EU roaming regulation, which guarantees EU citizens free roaming in EU countries, does not automatically apply to Swiss mobile customers.

Swiss providers nevertheless frequently offer EU roaming – but as a voluntary service, which is structured very differently depending on the plan and provider. You can find more background information in our article on roaming in Switzerland 2026.

Fair Use Limits: The Hidden Cost Trap

Many Swiss mobile plans advertise «roaming included» or «EU roaming in the plan». But almost always a fair use limit applies – a data cap that you can use free of charge in EU countries. Anyone who exceeds it pays additional costs that can range from CHF 0.05 to CHF 0.50 per MB depending on the provider.

Typical fair use limits at Swiss providers:

• Major providers (Swisscom, Salt, Sunrise): often 10–25 GB roaming data per month
• Discount providers (Yallo, Wingo, Lebara, etc.): often 1–5 GB or no roaming included at all

On a weekend trip to Paris where you watch an hour of Netflix in HD each evening, you quickly consume 3–6 GB just for streaming. This can already exhaust a fair use limit.

Countries Outside the EU

In Turkey, the Maldives or the USA, different rules apply. There, roaming costs are almost always significantly higher, and many plans don't include these countries at all. Here it's worth either getting a local SIM card or a special travel data package.

Comparison: Mobile Plans With and Without Roaming Packages

Before travelling abroad, it's worth taking a look at your current mobile plan. Three points are crucial:

1. Is EU roaming included? And if so, how many GB?
2. What does data consumption beyond the limit cost?
3. Are there bookable add-on packages for travel?

With major providers like Swisscom, Sunrise or Salt, EU roaming packages are usually included in the plan – but often with limits that can be tight for streaming-intensive travellers. Discount providers like Yallo or Wingo offer cheaper base rates but often have more limited roaming options.

Rule of thumb: Anyone who regularly travels to EU countries and streams there should plan for at least 10 GB of roaming data per month. For long-term travellers or families, plans with unlimited or very large roaming volumes are recommended.

Practical Tips: How to Save Roaming Data When Streaming

1. Offline Downloads Before the Trip

The most effective way to avoid roaming costs when streaming: download content before departure, while you're on Swiss Wi-Fi.

• Netflix: Up to 100 simultaneous downloads possible (depending on subscription tier). Series seasons can be downloaded completely with just a few clicks.
• Disney+: Download function also available, number varies depending on subscription.
• YouTube: With YouTube Premium you can save videos offline.
• Spotify: Download playlists and albums for offline use.

A full download storage easily replaces 10–20 hours of streaming – without consuming a single roaming byte.

2. Reduce Video Quality in the App Settings

If you do stream online: manually set the quality to SD or low in the app. On Netflix, this can be done under «App Settings» → «Data Usage». This reduces consumption from 3 GB to 0.3 GB per hour – a factor of 10.

3. Use Wi-Fi at the Hotel or Airbnb

Hotels, holiday apartments and cafés usually offer Wi-Fi. For data-intensive content, it's worth waiting for a Wi-Fi connection. But pay attention to security: public Wi-Fi networks are not always trustworthy. A VPN can be useful here.

4. Activate Data Saver Mode

Both Android and iOS offer system-wide data saver modes that restrict background data consumption by apps. This prevents apps from consuming data in the background while you're not streaming.

5. Manually Deactivate Roaming and Only Activate It When Needed

If you know you'll be using Wi-Fi for a longer period, you can deactivate roaming on your smartphone. This prevents unwanted costs from automatic updates or background processes.

Case Studies: Weekend Trip vs. Long-Term Travel

Weekend Trip (2–3 days, e.g. Berlin or Vienna)

Scenario: You watch an hour of Netflix in HD each evening and use Google Maps and social media during the day.

• Netflix HD: 2 × 1.5 GB = 3 GB
• Navigation, social media, messaging: approx. 0.5–1 GB
• Total: approx. 4–5 GB

Recommendation: A plan with at least 5 GB EU roaming is sufficient. With offline downloads, 1–2 GB is enough.

Family Holiday (2 weeks, e.g. Spain)

Scenario: Two adults and two children, 1–2 hours of streaming per day on various devices, plus navigation and communication.

• Streaming: 4 people × 1.5 hours × 1.5 GB × 14 days = approx. 126 GB
• Other: approx. 5–10 GB
• Total: well over 100 GB

Recommendation: Offline downloads are essential here. If you still want to stream online, you should consider a plan with a very large roaming volume or a local SIM card for Spain. Many EU SIM cards are available for a few euros and offer generous data packages.

Business Trip (1 week, various EU countries)

Scenario: Daily video calls, an hour of streaming in the evening, heavy data usage for emails and cloud services.

• Video calls (1 hour/day in HD): approx. 7 × 1.5 GB = 10.5 GB
• Streaming: 7 × 1.5 GB = 10.5 GB
• Other: approx. 3–5 GB
• Total: approx. 25 GB

Recommendation: A business plan with at least 20–25 GB EU roaming. Alternatively: conduct video calls via hotel Wi-Fi and switch streaming to offline downloads.

Conclusion and Recommendations

Streaming abroad is convenient – but only if you're prepared. The most important points at a glance:

• Download content before the trip. This is the cheapest and most reliable solution.
• Reduce the streaming quality to SD if you do watch online.
• Check your plan for fair use limits and roaming conditions before you travel.
• Plan realistically: one hour of HD streaming consumes 1–3 GB – that adds up quickly.
• For longer trips: consider a local SIM card or a plan with a large roaming volume.
