Short answer
The simplest start is a smartphone with the official app. For a TV, you also need a supported playback route, a stable hotspot or router and suitable power. Plan mobile data before the trip: viewing time and actual usage matter more than the plan’s maximum LTE or 5G speed.
Duration
Multiply hours per day by trip days.
Usage
Enter measured GB per hour or a clearly labelled example.
Reserve
Set aside data for other use and check your plan at the destination.
GB measures data volume; Mbps measures connection speed.
Estimate your travel data budget
Estimate: hours × days × GB per hour. Actual use depends on the stream. The reserve is deducted from the budget first, down to 0 GB at most. A negative remaining budget shows a shortfall. Days of coverage assume your daily use.

Enter valid, non-negative numbers in all fields. Viewer, stream and day counts must be whole numbers; hours per day cannot exceed 24.

Three setups that differ in daily use
Choose based on screen size and equipment. A permanent router installation is not justified at every campsite.
| Setup | Suitable for | Check first |
|---|---|---|
| Smartphone alone | Short programmes, one viewer, little equipment | App, mobile reception, battery and data allowance |
| Phone hotspot plus TV or streaming device | Larger screen using devices you already own | Hotspot connection, app on target device, power for all devices |
| Mobile router plus TV | Several devices and regular use | Supported mobile bands, plan, placement and power |
A mobile router cannot create reception where there is no network. It can offer another placement and a connection that stays available. Actual coverage at your site, including congestion at viewing time, is what matters.
Set up the hotspot at home first
Set it up at home while you have help and a second way to connect. Connect the playback device to your protected hotspot and open familiar content. Then restart: does it find the network again, and can you continue with the regular remote?
For iPhone, Apple describes Personal Hotspot. Availability also depends on the mobile plan. The target device still needs a supported app; a hotspot does not replace a missing TV app.
If you want to use TELOS, check the device overview and your own source. Access working on your home network is not automatically approved for every destination or mobile connection. The travel checklist covers that separate question.
How long will 50 GB last for TV?
Divide usable data by use per hour. Zattoo’s figures for mobile devices give up to 1.3 GB per hour for SD, 2.2 GB for HD and 3.5 GB for Full HD as estimates. These are figures for that service’s mobile apps, not TELOS measurements or a promise for every TV stick.
Using those example figures, 50 GB lasts about 38 hours in SD, 23 hours in HD or 14 hours in Full HD. If you reserve 10 GB for navigation, messages and other use, 40 GB remain: about 31, 18 or 11 hours. Rounding does not make an estimate more precise than the assumed usage.
For a trip, multiply hours per day by trip days and use per hour. Ten days at two hours daily and an assumed 2.2 GB per hour use 44 GB for TV alone. Plan other use separately. Updates and connected devices share the same allowance.
Measure your own use instead of relying on a generic figure
Check your phone or router’s data counter just before and after a short playback. Avoid other downloads and background updates while testing where possible. Record the app, device, quality setting and duration.
A 30-minute test using 0.9 GB more data works out to 1.8 GB per hour. That is one session’s observation, not a fixed app property. Programmes and adaptive picture quality can change usage. Repeat the test before planning your full trip allowance.
You can choose lower quality only where the app and platform offer it. Do not assume an option in a phone guide also exists on a smart TV. The bandwidth guide also explains the difference between speed and data volume.
Plan power and device placement
For every device, note its planned power source: phone, router, TV and any streaming stick. Use manufacturer-approved power supplies and ports. A TV’s USB port may turn off with the TV, so check startup and power after switching it back on.
With limited battery capacity, include the power use of all devices in your trip plan. Fast mobile service is no help if the setup runs out of power. We do not give a general runtime because batteries, devices and use vary.
Compare mobile reception at practical locations around the vehicle. Keep devices within their approved operating temperature and out of direct sun. Check again in the evening, when many people at the campsite may share a cell.
Check before departure and at the campsite
Before travelling, install the required apps, test sign-in, check channel rights at your destination and read plan and roaming terms. An EU data allowance and a TV subscription are separate contracts. A large domestic plan may have different data rules abroad.
At the campsite, check reception and remaining data first, then start one stream. Connect other devices only after that works. For interruptions, use the buffering guide.
If you will be somewhere without reliable network access, plan suitable officially supported offline content in advance. A TELOS download depends on a supported source and platform; a watchlist is not an offline copy. Test the finished download on the intended device before relying on it while away.
Frequently asked questions
Is 50 GB enough for two weeks of TV?
It depends on viewing time, quality and other use. At an assumed 2.2 GB per hour, 50 GB covers about 23 hours before reserving data for other services.
Can I connect a TV stick to my phone hotspot?
You can test this if the stick, hotspot and plan support the route. Also check app availability, power and data use.
Is a mobile router always faster than a phone?
No. Coverage, supported radio technology, placement and congestion matter. A router can be convenient but does not guarantee reception.
Does the stated data use also apply to TELOS?
No. The examples come from Zattoo’s mobile app help. Measure your own source and device version when using TELOS.
