Not every device needs a phone number. A tablet for the children on long car journeys, a pocket router for a holiday cottage or a second phone kept just for work email only needs mobile data. Paying for a full call-and-text plan on each of them wastes money every month. A data only SIM Belgium users can buy without a contract solves the problem: you pick a data allowance, activate it on a SIM or eSIM, and top up only when you need it again.
Where a Data-Only Plan Makes Sense
Tablets
Many tablets have a SIM slot or eSIM support that sits unused. Adding a small data bundle lets them work on the train, in the car or at a café without hunting for Wi-Fi, which is ideal for streaming a downloaded series or keeping children entertained on the road.
Mobile Routers and Hotspots
A portable router turns one data bundle into Wi-Fi for several devices. It is a practical setup for a weekend in the Ardennes, a student flat waiting for broadband installation or a market stall that needs a card terminal online.
A Second Phone
If you carry a work phone, a data-only line keeps email, messaging apps and maps running without paying for minutes you never use. The same goes for an older phone kept as a navigation device in the car.
The Four Data Bundles
Each prepaid data plan for tablet or router below lasts 30 days, runs on the Telenet/Base 4G and 5G network and includes the same amount of data for roaming in the EU, Ukraine and Moldova.
| Bundle | Data | EU roaming | Price / 30 days | Best for |
|---|---|---|---|---|
| Data 10 | 2GB | 2GB | 10 EUR | Email, maps and messaging |
| Data 15 | 3GB | 3GB | 15 EUR | Light browsing on a tablet |
| Data 20 | 5GB | 5GB | 20 EUR | Music and occasional video |
| Data 25 | 10GB | 10GB | 25 EUR | Routers and regular streaming |
For most tablets, 3GB to 5GB a month is plenty if downloads happen on home Wi-Fi. A router shared by several people will burn through data faster, so the 10GB data plan Belgium option is the safer choice there. All four bundles are eSIM-ready.
Data-Only or a Full Plan?
The choice depends on how the device is used. If it never makes calls, a data bundle is the leaner option, because every euro goes on gigabytes rather than minutes. If the second device also needs a number, for example a work phone that receives calls, a national plan with unlimited calls and a larger data allowance may end up better value. A quick rule: when you need more than 10GB on that line every month, compare the price per gigabyte with the national plans before deciding. For a tablet or a router used a few days a week, though, a data-only bundle is hard to beat.
Using Your Data Abroad
Because each bundle includes the same allowance for roaming in the EU, Ukraine and Moldova, a tablet or router set up in Belgium keeps working on a ski trip to France or a city break in Amsterdam. There is no separate travel pass to buy for European trips, which makes these bundles handy for families who want the children’s tablet online during the drive and at the holiday rental.
Setting Up an eSIM in Five Steps
- Check that your tablet or phone supports eSIM in its settings menu.
- Order the eSIM online and choose your data bundle.
- Scan the QR code you receive with the device you want to connect.
- Label the new line clearly, for example “Data”, if the device already has another SIM.
- Turn on mobile data for that line and you are online within minutes.
A Few Tips to Make Your Data Last
- Download films, playlists and maps on Wi-Fi before you leave home.
- Lower video quality in streaming apps when you are on mobile data.
- Turn off automatic app updates and cloud photo backups on the data line.
Closing Thoughts
A data-only bundle is the easiest way to bring a tablet, router or second phone online without paying for calls you will never make. Start with 3GB or 5GB for a tablet and move up to 10GB if several devices share one connection. Since there is no contract, you can switch bundles from one month to the next.
