How much internet do I need? Data and speed in Switzerland
For your phone, your monthly usage in GB matters; for your home connection, the main issue is the speed needed simultaneously in Mbit/s. Start with your own measurements rather than a general average. Ten hours of HD streaming alone can use up to 30 GB, while Netflix recommends at least 15 Mbit/s for a single 4K stream. These are two different questions.
Sources checked: 1 November 2026. The following usage scenarios are calculation aids, not measurements of your connection or averages for the Swiss population.
GB measure volume, Mbit/s measure speed
A gigabyte describes a quantity of data. Mbit/s describe how quickly data is transferred. The calculations here use decimal units: 1 GB = 1000 MB and 1 byte = 8 bits. A higher maximum speed does not automatically mean higher usage. However, usage can rise if apps consequently select a higher video quality.
Download matters for receiving videos and files; upload matters for your camera in video calls, cloud backups and sending large files. A plan with fast download but slow upload may therefore be unsuitable for working from home.
How much data individual applications need
Application | Provider specification | Planning example |
Netflix, low quality | Up to 0.3 GB per hour | 10 hours: up to 3 GB |
Netflix, medium quality | Up to 0.7 GB per hour | 10 hours: up to 7 GB |
Netflix, HD / 4K | Up to 3 / 7 GB per hour | 10 hours: up to 30 / 70 GB |
Zoom, 720p one-to-one call | 1.2 Mbit/s recommended in each direction | Calculated total of around 1.08 GB/h |
Zoom, 1080p | 3.8 upload + 3.0 download recommended | Calculated total of around 3.06 GB/h |
Sources: Netflix data usage and Zoom system requirements. Zoom specifies bandwidth requirements, not guaranteed usage figures. The conversion assumes one hour of constant utilisation: total Mbit/s × 3600 ÷ 8 ÷ 1000. Actual usage depends on factors including resolution, movement and network conditions. A uniform figure of 300 MB per hour of video conferencing is therefore unsuitable.
How to work out your mobile data needs
Check three complete billing periods and a holiday month in your provider's app. Compare them with your phone's data usage display; its counter must cover the same period. Record domestic data, roaming and hotspot usage separately. Wi-Fi usage does not belong in your mobile data budget.
Your measured everyday usage | Useful comparison | What to check |
Up to about 3 GB, mostly Wi-Fi | Small bundles versus pay-as-you-go prepaid | Bundle expiry and costs on usage days |
About 8 GB, occasional videos | For example, 12 GB versus unlimited | Add-on bundles and the actual extra cost |
About 30 GB or regular hotspot use | Large bundles versus unlimited | Speed limit, coverage at work, fair use |
Holidays with extensive navigation and video | Separate roaming budget | Country list and included allowance rather than a Swiss flat rate |
These thresholds are editorial guidance. For example, with peak usage of 8 GB, a 30 percent reserve gives 10.4 GB; a 10-GB bundle does not fully cover that reserve. Choose a buffer based on your own fluctuations. There is no universal requirement for 30 or 50 percent more data. Offline downloads over Wi-Fi may make more sense than a permanently larger bundle.
How much speed makes sense at home
Netflix recommends at least 3 Mbit/s per stream for 720p, 5 Mbit/s for 1080p and 15 Mbit/s for 4K. Source: Netflix speed recommendation. Based on this recommendation, two simultaneous 4K streams need a combined 30 Mbit/s; other devices and spare capacity come on top. A connection offering 50 to 100 Mbit/s can therefore be a reasonable starting point for a modest household, provided that performance actually reaches the place where you use it.
More speed can help with large downloads: at a constant 100 Mbit/s, a 50-GB file theoretically takes about 67 minutes; at 1 Gbit/s, just under 7 minutes. Servers, Wi-Fi and protocol overhead increase this time. Latency and stability also matter for gaming; a higher advertised maximum rate does not automatically fix coverage gaps or poor Wi-Fi.
Choosing a plan: usage first, price second
After measuring your usage, compare costs over the same period, including activation, add-on bundles and the price after a promotion. Unlimited data is also available on prepaid plans, but this does not imply unlimited speed or free roaming. A small plan may suffice for occasional usage. An unlimited offer may be cheaper for heavy daily usage. Without your usage profile, there is no universal winner.
